The irq_desc::kstat_irqs member is a per-CPU variable of type int, which is
only capable of counting. A snapshot mechanism for interrupt statistics
will be added soon, which requires an additional variable to store the
snapshot.
To facilitate expansion, convert kstat_irqs here to a struct containing
only the count.

Recent tightening of the opcode table in binutils so as to consistently
disallow the assembly or disassembly of CP0 instructions not supported
by the processor architecture chosen has caused a regression like below:
arch/mips/dec/prom/locore.S: Assembler messages:
arch/mips/dec/prom/locore.S:29: Error: opcode not supported on this processor: r4600 (mips3) `rfe'
in a piece of code used to probe for memory with PMAX DECstation models,
which have non-REX firmware. Those computers always have an R2000 CPU
and consequently the exception handler used in memory probing uses the
RFE instruction, which those processors use.
While adding 64-bit support this code was correctly excluded for 64-bit
configurations, however it should have also been excluded for irrelevant
32-bit configurations. Do this now then, and only enable PMAX memory
probing for R3k systems.

message
The config for MIPS R4000-series processors is named CPU_R4X00 with
upper-case X, not CPU_R4x00 as the error message suggests.
Hence, ./scripts/checkkconfigsymbols.py reports this invalid reference:
CPU_R4x00
Referencing files: arch/mips/dec/prom/init.c
When human users encounter this error message, they probably just deal
with this minor discrepancy; so, the spelling never was a big deal here.
Still, the script ./scripts/checkkconfigsymbols.py has been quite useful
to identify a number of bugs with Kconfig symbols and deserves to be
executed and checked regularly.
So, repair the error message to reduce the reports made the script and
simplify to use this script, as new issues are easier to spot when the
list of reports is shorter.

After making the brcmstb_gisb driver modular with 707a4cdf86e5 ("bus:
brcmstb_gisb: Allow building as module") Guenter reported that mips
allmodconfig failed to link because board_be_handler was referenced.
Thomas indicated that if we were to continue making the brcmstb_gisb
driver modular for MIPS we would need to introduce a function that
allows setting the board_be_handler and export that function towards
modules.
This is what is being done here: board_be_handler is made static and is
now settable with a mips_set_be_handler() function which is exported.

Disabling lock debugging due to kernel taint
caused by an attempt to free bootmem space that as from
commit b93ddc4f9156 ("mips: Reserve memory for the kernel image resources")
has not been anymore reserved due to the removal of generic MIPS arch code
that used to reserve all the memory from the beginning of RAM up to the
kernel load address.
This memory does need to be reserved on DEC platforms however as it is
used by REX firmware as working area, as per the TURBOchannel firmware
specification[1]:
Table 2-2 REX Memory Regions
-------------------------------------------------------------------------
Starting Ending
Region Address Address Use
-------------------------------------------------------------------------
0 0xa0000000 0xa000ffff Restart block, exception vectors,
REX stack and bss
1 0xa0010000 0xa0017fff Keyboard or tty drivers
2 0xa0018000 0xa001f3ff 1) CRT driver
3 0xa0020000 0xa002ffff boot, cnfg, init and t objects
4 0xa0020000 0xa002ffff 64KB scratch space
-------------------------------------------------------------------------
1) Note that the last 3 Kbytes of region 2 are reserved for backward
compatibility with previous system software.
-------------------------------------------------------------------------
(this table uses KSEG2 unmapped virtual addresses, which in the MIPS
architecture are offset from physical addresses by a fixed value of
0xa0000000 and therefore the regions referred do correspond to the
beginning of the physical address space) and we call into the firmware
on several occasions throughout the bootstrap process. It is believed
that pre-REX firmware used with non-TURBOchannel DEC platforms has the
same requirements, as hinted by note #1 cited.
Recreate the discarded reservation then, in DEC platform code, removing
the crash.

Recently all usages of setup_irq() was replaced by request_irq().
request_irq() does a few sanity checks that were not done in
setup_irq(), if they fail irq registration will fail. One of the check
is to ensure that non-NULL dev_id is passed in the case of shared irq.
This caused malta on qemu to hang.
Fix it by passing handler as dev_id to all request_irq()'s that are
shared. For sni, instead of passing non-NULL dev_id, remove shared irq
flags.

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().
remove_irq() has been replaced by free_irq() as well.

reported by kbuild test robot <lkp@intel.com> of which one was reported

Since struct timespec is not y2038 safe on 32bit machines, this patch
converts update_persistent_clock() to update_persistent_clock64() using
struct timespec64.
The rtc_mips_set_time() and rtc_mips_set_mmss() interfaces were using
'unsigned long' type that is not y2038 safe on 32bit machines, moreover
there is only one platform implementing rtc_mips_set_time() and two
platforms implementing rtc_mips_set_mmss(), so we can just make them each
implement update_persistent_clock64() directly, to get that helper out
of the common mips code by removing rtc_mips_set_time() and
rtc_mips_set_mmss() interfaces.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

triggering with with the CPU_DADDI_WORKAROUNDS option set and the DADDIU
instruction. This is because with that option in place the instruction
becomes a macro, which expands to an LI/DADDU (or actually ADDIU/DADDU)
sequence that uses $at as a temporary register.
With CPU_DADDI_WORKAROUNDS we only support `-msym32' compilation though,
and this is already enforced in arch/mips/Makefile, so choose the 32-bit
expansion variant for the supported configurations and then replace the
64-bit variant with #error just in case.

While examining output from trial builds with -Wformat-security enabled,
many strings were found that should be defined as "const", or as a char
array instead of char pointer. This makes some static analysis easier,
by producing fewer false positives.
As these are all trivial changes, it seemed best to put them all in a
single patch rather than chopping them up per maintainer.

Historically a lot of these existed because we did not have
a distinction between what was modular code and what was providing
support to modules via EXPORT_SYMBOL and friends. That changed
when we forked out support for the latter into the export.h file.
This means we should be able to reduce the usage of module.h
in code that is obj-y Makefile or bool Kconfig. In the case of
some code where it is modular, we can extend that to also include
files that are building basic support functionality but not related
to loading or registering the final module; such files also have
no need whatsoever for module.h
The advantage in removing such instances is that module.h itself
sources about 15 other headers; adding significantly to what we feed
cpp, and it can obscure what headers we are effectively using.
Since module.h might have been the implicit source for init.h
(for __init) and for export.h (for EXPORT_SYMBOL) we consider each
instance for the presence of either and replace/add as needed.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
Build coverage of all the mips defconfigs revealed the module.h
header was masking a couple of implicit include instances, so
we add the appropriate headers there.

When expanding the la or dla pseudo-instruction in a delay slot the GNU
assembler will complain should the pseudo-instruction expand to multiple
actual instructions, since only the first of them will be in the delay
slot leading to the pseudo-instruction being only partially executed if
the branch is taken. Use of PTR_LA in the dec int-handler.S leads to
such warnings:
arch/mips/dec/int-handler.S: Assembler messages:
arch/mips/dec/int-handler.S:149: Warning: macro instruction expanded into multiple instructions in a branch delay slot
arch/mips/dec/int-handler.S:198: Warning: macro instruction expanded into multiple instructions in a branch delay slot
Avoid this by open coding the PTR_LA macros.

has been used -- do not register the FPU interrupt in such a case
either.

Implement a cheap way to count FPU interrupts for R2k/R3k DECstation
systems. Do this manually in handcoded assembly, rather than calling
`kstat_incr_irq_this_cpu' that would require setting up a stack frame
and a lot of redirection. This is not going to be a problem because the
FPU interrupt is local to the CPU and also there is one CPU only anyway.
So at bootstrap determine the address of the correct location within
`struct irq_desc', and then only refer to it directly in the interrupt
handler.

On R4k DECstations the Halt button is wired to the NMI processor input
rather than an ordinary interrupt input such as on R3k DECstations. This
is possible with a different design of the CPU daughtercard that routes
the Halt button line from the baseboard connector. Additionally the
interrupt input has been reused for a different purpose on the KN04 and
KN05 R4k CPU daughtercards so it is better kept masked.

Commit 231a35d37293ab88d325a9cb94e5474c156282c0 [[MIPS] RM: Collected
changes] broke DECstation support by introducing an incompatible copy of
arch/mips/dec/prom/call_o32.S in arch/mips/fw/lib/, built unconditionally.
The copy happens to land earlier of the two among the modules used in the
link and is therefore chosen for the DECstation rather than the intended
original. As a result random kernel data is corrupted because a pointer
to the "%s" formatted output template is used as a temporary stack pointer
rather than being passed down to prom_printf. This also explains why
prom_printf still works, up to a point -- the next argument is the actual
string to output so it works just fine as the output template until enough
kernel data has been corrupted to cause a crash.
This change adjusts the modified wrapper in arch/mips/fw/lib/call_o32.S to
let callers request no stack switching by passing a null temporary stack
pointer in $a1, reworks the DECstation callers to work with the updated
interface and removes the old copy from arch/mips/dec/prom/call_o32.S. A
few minor readability adjustments are included as well, most importantly
O32_SZREG is now used throughout where applicable rather than hardcoded
multiplies of 4 and $fp is used to access the argument save area as a more
usual register to operate the stack with rather than $s0.
Finally an update is made to the temporary stack space used by the SNI
platform to guarantee 8-byte alignment as per o32 requirements.

This change complements commits d0da7c002f7b2a93582187a9e3f73891a01d8ee4
[MIPS: DEC: Convert to new irq_chip functions] and
5359b938c088423a28c41499f183cd10824c1816 [MIPS: DECstation I/O ASIC DMA
interrupt handling fix] and implements automatic handling of the two
classes of DMA interrupts the I/O ASIC implements, informational and
errors.
Informational DMA interrupts do not stop the transfer and use the
`handle_edge_irq' handler that clears the request right away so that
another request may be recorded while the previous is being handled.
DMA error interrupts stop the transfer and require a corrective action
before DMA can be reenabled. Therefore they use the `handle_fasteoi_irq'
handler that only clears the request on the way out. Because MIPS
processor interrupt inputs, one of which the I/O ASIC's interrupt
controller is cascaded to, are level-triggered it is recommended that
error DMA interrupt action handlers are registered with the IRQF_ONESHOT
flag set so that they are run with the interrupt line masked.
This change removes the export of clear_ioasic_dma_irq that now does not
have to be called by device drivers to clear interrupts explicitly
anymore. Originally these interrupts were cleared in the .end handler of
the `irq_chip' structure, before it was removed.

This change complements commit d0da7c002f7b2a93582187a9e3f73891a01d8ee4
and brings clear_ioasic_irq back, renaming it to clear_ioasic_dma_irq at
the same time, to make I/O ASIC DMA interrupts functional.
Unlike ordinary I/O ASIC interrupts DMA interrupts need to be deasserted
by software by writing 0 to the respective bit in I/O ASIC's System
Interrupt Register (SIR), similarly to how CP0.Cause.IP0 and CP0.Cause.IP1
bits are handled in the CPU (the difference is SIR DMA interrupt bits are
R/W0C so there's no need for an RMW cycle). Otherwise the handler is
reentered over and over again.
The only current user is the DEC LANCE Ethernet driver and its extremely
uncommon DMA memory error handler that does not care when exactly the
interrupt is cleared. Anticipating the use of DMA interrupts by the Zilog
SCC driver this change however exports clear_ioasic_dma_irq for device
drivers to choose the right application-specific sequence to clear the
request explicitly rather than calling it implicitly in the .irq_eoi
handler of `struct irq_chip'. Previously these interrupts were cleared in
the .end handler of the said structure, before it was removed.

Not all I/O ASIC versions have the free-running counter implemented, an
early revision used in the 5000/1xx models aka 3MIN and 4MIN did not have
it. Therefore we cannot unconditionally use it as a clock source.
Fortunately if not implemented its register slot has a fixed value so it
is enough if we check for the value at the end of the calibration period
being the same as at the beginning.
This also means we need to look for another high-precision clock source on
the systems affected. The 5000/1xx can have an R4000SC processor
installed where the CP0 Count register can be used as a clock source.
Unfortunately all the R4k DECstations suffer from the missed timer
interrupt on CP0 Count reads erratum, so we cannot use the CP0 timer as a
clock source and a clock event both at a time. However we never need an
R4k clock event device because all DECstations have a DS1287A RTC chip
whose periodic interrupt can be used as a clock source.
This gives us the following four configuration possibilities for I/O ASIC
DECstations:
1. No I/O ASIC counter and no CP0 timer, e.g. R3k 5000/1xx (3MIN).
2. No I/O ASIC counter but the CP0 timer, i.e. R4k 5000/150 (4MIN).
3. The I/O ASIC counter but no CP0 timer, e.g. R3k 5000/240 (3MAX+).
4. The I/O ASIC counter and the CP0 timer, e.g. R4k 5000/260 (4MAX+).
For #1 and #2 this change stops the I/O ASIC free-running counter from
being installed as a clock source of a 0Hz frequency. For #2 it also
arranges for the CP0 timer to be used as a clock source rather than a
clock event device, because having an accurate wall clock is more
important than a high-precision interval timer. For #3 there is no
change. For #4 the change makes the I/O ASIC free-running counter
installed as a clock source so that the CP0 timer can be used as a clock
event device.
Unfortunately the use of the CP0 timer as a clock event device relies on a
succesful completion of c0_compare_interrupt. That never happens, because
while waiting for a CP0 Compare interrupt to happen the function spins in
a loop reading the CP0 Count register. This makes the CP0 Count erratum
trigger reliably causing the interrupt waited for to be lost in all cases.
As a result #4 resorts to using the CP0 timer as a clock source as well,
just as #2. However we want to keep this separate arrangement in case
(hope) c0_compare_interrupt is eventually rewritten such that it avoids
the erratum.

This change corrects DECstation HRT calibration, by removing the following
bugs:
1. Calibration period selection -- HZ / 10 has been chosen, however on
DECstation computers, HZ never divides by 10, as the choice for HZ is
among 128, 256 and 1024. The choice therefore results in a systematic
calibration error, e.g. 6.25% for the usual choice of 128 for HZ:
128 / 10 * 10 = 120
(128 - 120) / 128 -> 6.25%
The change therefore makes calibration use HZ / 8 that is always
accurate for the HZ values available, getting rid of the systematic
error.
2. Calibration starting point synchronisation -- the duration of a number
of intervals between DS1287A periodic interrupt assertions is measured,
however code does not ensure at the beginning that the interrupt has
not been previously asserted. This results in a variable error of e.g.
up to another 6.25% for the period of HZ / 8 (8.(3)% with the original
HZ / 10 period) and the usual choice of 128 for HZ:
1 / 16 -> 6.25%
1 / 12 -> 8.(3)%
The change therefore adds an initial call to ds1287_timer_state that
clears any previous periodic interrupt pending.
The same issue applies to both I/O ASIC counter and R4k CP0 timer
calibration on DECstation systems as similar code is used in both cases
and both pieces of code are covered by this fix.
On an R3400 test system used this fix results in a change of the I/O ASIC
clock frequency reported from values like:
I/O ASIC clock frequency 23185830Hz
to:
I/O ASIC clock frequency 24999288Hz
removing the miscalculation by 6.25% from the systematic error and (for
the individual sample provided) a further 1.00% from the variable error,
accordingly. The nominal I/O ASIC clock frequency is 25MHz on this
system.
Here's another result, with the fix applied, from a system that has both
HRTs available (using an R4400 at 60MHz nominal):
MIPS counter frequency 59999328Hz
I/O ASIC clock frequency 24999432Hz

slightly ahead of current time and the periodic update of RTC fails. The
message is a nuisance and repeats spamming the log.
See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS
Rather than just removing the message, make it show only once and reduce
severity since it indicates a normal and non urgent condition.
