If get_maintainer is not given any filename arguments on the command line,
the standard input is read for a patch.
But checking if a VCS has a file named &STDIN is not a good idea and fails.
Verify the nominal input file is not &STDIN before checking the VCS.

This reverts commit 874f9c7da9a4acbc1b9e12ca722579fb50e4d142.
Geert Uytterhoeven reports:
"This change seems to have an (unintendent?) side-effect.
Before, pr_*() calls without a trailing newline characters would be
printed with a newline character appended, both on the console and in
the output of the dmesg command.
After this commit, no new line character is appended, and the output
of the next pr_*() call of the same type may be appended, like in:
- Truncating RAM at 0x0000000040000000-0x00000000c0000000 to -0x0000000070000000
- Ignoring RAM at 0x0000000200000000-0x0000000240000000 (!CONFIG_HIGHMEM)

Joe Perches says:
"No, that is not intentional.
The newline handling code inside vprintk_emit is a bit involved and
for now I suggest a revert until this has all the same behavior as
earlier"

Pull tracing fix from Steven Rostedt:
"Fix tick_stop tracepoint symbols for user export.
Luiz Capitulino noticed that the tick_stop tracepoint wasn't being
parsed properly by the tracing user space tools.
This was due to the TRACE_DEFINE_ENUM() being set to a define, when it
should have been set to the enum itself. The define was of the MASK
that used the BIT to shift. The BIT was the enum and by adding that,
everything gets converted nicely. The MASK is still kept just in case
it gets converted to an enum in the future"

To distinguish non-slab pages charged to kmemcg we mark them PageKmemcg,
which sets page->_mapcount to -512. Currently, we set/clear PageKmemcg
in __alloc_pages_nodemask()/free_pages_prepare() for any page allocated
with __GFP_ACCOUNT, including those that aren't actually charged to any
cgroup, i.e. allocated from the root cgroup context. To avoid overhead
in case cgroups are not used, we only do that if memcg_kmem_enabled() is
true. The latter is set iff there are kmem-enabled memory cgroups
(online or offline). The root cgroup is not considered kmem-enabled.
As a result, if a page is allocated with __GFP_ACCOUNT for the root
cgroup when there are kmem-enabled memory cgroups and is freed after all
kmem-enabled memory cgroups were removed, e.g.
# no memory cgroups has been created yet, create one
mkdir /sys/fs/cgroup/memory/test
# run something allocating pages with __GFP_ACCOUNT, e.g.
# a program using pipe
dmesg | tail
# remove the memory cgroup
rmdir /sys/fs/cgroup/memory/test
we'll get bad page state bug complaining about page->_mapcount != -1:
BUG: Bad page state in process swapper/0 pfn:1fd945c
page:ffffea007f651700 count:0 mapcount:-511 mapping: (null) index:0x0
flags: 0x1000000000000000()
To avoid that, let's mark with PageKmemcg only those pages that are
actually charged to and hence pin a non-root memory cgroup.

The symbols used in the tick_stop tracepoint were not being converted
properly into integers in the trace_stop format file. Instead we had this:
print fmt: "success=%d dependency=%s", REC->success,
__print_symbolic(REC->dependency, { 0, "NONE" },
{ (1 << TICK_DEP_BIT_POSIX_TIMER), "POSIX_TIMER" },
{ (1 << TICK_DEP_BIT_PERF_EVENTS), "PERF_EVENTS" },
{ (1 << TICK_DEP_BIT_SCHED), "SCHED" },
{ (1 << TICK_DEP_BIT_CLOCK_UNSTABLE), "CLOCK_UNSTABLE" })
User space tools have no idea how to parse "TICK_DEP_BIT_SCHED" or the other
symbols used to do the bit shifting. The reason is that the conversion was
done with using the TICK_DEP_MASK_* symbols which are just macros that
convert to the BIT shift itself (with the exception of NONE, which was
converted properly, because it doesn't use bits, and is defined as zero).
The TICK_DEP_BIT_* needs to be denoted by TRACE_DEFINE_ENUM() in order to
have this properly converted for user space tools to parse this event.

The recent commit 599d0c954f91 ("mm, vmscan: move LRU lists to node"),
changed memory management code so that show_mem() is no longer safe to
call prior to setup_per_cpu_pageset(), as pgdat->per_cpu_nodestats will
still be NULL. This causes an oops on metag due to the call to
show_mem() from mem_init():
node_page_state_snapshot(...) + 0x48
pgdat_reclaimable(struct pglist_data * pgdat = 0x402517a0)
show_free_areas(unsigned int filter = 0) + 0x2cc
show_mem(unsigned int filter = 0) + 0x18
mem_init()
mm_init()
start_kernel() + 0x204
This wasn't a problem before with zone_reclaimable() as zone_pcp_init()
was already setting zone->pageset to &boot_pageset, via setup_arch() and
paging_init(), which happens before mm_init():
zone_pcp_init(...)
free_area_init_core(...) + 0x138
free_area_init_node(int nid = 0, ...) + 0x1a0
free_area_init_nodes(...) + 0x440
paging_init(unsigned long mem_end = 0x4fe00000) + 0x378
setup_arch(char ** cmdline_p = 0x4024e038) + 0x2b8
start_kernel() + 0x54
No other arches appear to call show_mem() during boot, and it doesn't
really add much value to the log, so lets just drop it from mem_init().

According to E-EDID spec 1.3, table 3.9, a digital video sink with the
"DFP 1.x compliant TMDS" bit set is "signal compatible with VESA DFP 1.x
TMDS CRGB, 1 pixel / clock, up to 8 bits / color MSB aligned".
For such displays, the DFP spec 1.0, section 3.10 "EDID support" says:
"If the DFP monitor only supports EDID 1.X (1.1, 1.2, etc.)
without extensions, the host will make the following assumptions:
1. 24-bit MSB-aligned RGB TFT
2. DE polarity is active high
3. H and V syncs are active high
4. Established CRT timings will be used
5. Dithering will not be enabled on the host"
So if we don't know the bit depth of the display from additional
colorimetry info we should assume 8 bpc / 24 bpp by default.
This patch adds info->bpc = 8 assignement for that case.

is unknown"
This reverts commit 013dd9e03872
("drm/i915/dp: fall back to 18 bpp when sink capability is unknown")
This commit introduced a regression into stable kernels,
as it reduces output color depth to 6 bpc for any video
sink connected to a Displayport connector if that sink
doesn't report a specific color depth via EDID, or if
our EDID parser doesn't actually recognize the proper
bpc from EDID.
Affected are active DisplayPort->VGA converters and
active DisplayPort->DVI converters. Both should be
able to handle 8 bpc, but are degraded to 6 bpc with
this patch.
The reverted commit was meant to fix
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=105331
A followup patch implements a fix for that specific bug,
which is caused by a faulty EDID of the affected DP panel
by adding a new EDID quirk for that panel.
DP 18 bpp fallback handling and other improvements to
DP sink bpc detection will be handled for future
kernels in a separate series of patches.
Please backport to stable.

Bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=105331
reports that the "AEO model 0" display is driven with 8 bpc
without dithering by default, which looks bad because that
panel is apparently a 6 bpc DP panel with faulty EDID.
A fix for this was made by commit 013dd9e03872
("drm/i915/dp: fall back to 18 bpp when sink capability is unknown").
That commit triggers new regressions in precision for DP->DVI and
DP->VGA displays. A patch is out to revert that commit, but it will
revert video output for the AEO model 0 panel to 8 bpc without
dithering.
The EDID 1.3 of that panel, as decoded from the xrandr output
attached to that bugzilla bug report, is somewhat faulty, and beyond
other problems also sets the "DFP 1.x compliant TMDS" bit, which
according to DFP spec means to drive the panel with 8 bpc and
no dithering in absence of other colorimetry information.
Try to make the original bug reporter happy despite the
faulty EDID by adding a quirk to mark that panel as 6 bpc,
so 6 bpc output with dithering creates a nice picture.
Tested by injecting the edid from the fdo bug into a DP connector
via drm_kms_helper.edid_firmware and verifying the 6 bpc + dithering
is selected.
This patch should be backported to stable.

When I initially added the unsafe_[get|put]_user() helpers in commit
5b24a7a2aa20 ("Add 'unsafe' user access functions for batched
accesses"), I made the mistake of modeling the interface on our
traditional __[get|put]_user() functions, which return zero on success,
or -EFAULT on failure.
That interface is fairly easy to use, but it's actually fairly nasty for
good code generation, since it essentially forces the caller to check
the error value for each access.
In particular, since the error handling is already internally
implemented with an exception handler, and we already use "asm goto" for
various other things, we could fairly easily make the error cases just
jump directly to an error label instead, and avoid the need for explicit
checking after each operation.
So switch the interface to pass in an error label, rather than checking
the error value in the caller. Best do it now before we start growing
more users (the signal handling code in particular would be a good place
to use the new interface).
So rather than
if (unsafe_get_user(x, ptr))
... handle error ..
the interface is now
unsafe_get_user(x, ptr, label);
where an error during the user mode fetch will now just cause a jump to
'label' in the caller.
Right now the actual _implementation_ of this all still ends up being a
"if (err) goto label", and does not take advantage of any exception
label tricks, but for "unsafe_put_user()" in particular it should be
fairly straightforward to convert to using the exception table model.
Note that "unsafe_get_user()" is much harder to convert to a clever
exception table model, because current versions of gcc do not allow the
use of "asm goto" (for the exception) with output values (for the actual
value to be fetched). But that is hopefully not a limitation in the
long term.
[ Also note that it might be a good idea to switch unsafe_get_user() to
actually _return_ the value it fetches from user space, but this
commit only changes the error handling semantics ]

In commit 874f9c7da9a4 ("printk: create pr_<level> functions"), new
pr_level defines were added to printk.c.
These new defines are guarded by an #ifdef CONFIG_PRINTK - however,
there is already a surrounding #ifdef CONFIG_PRINTK starting a lot
earlier in line 249 which means the newly introduced #ifdef is
unnecessary.
Let's remove it to avoid confusion.

Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.
No intended functional changes in this commit.

Commit abf545484d31 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.
Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

"This update is to allow architecture emulation containers to function
such that the emulation binary can be housed outside the container
itself. The container and fs parts both have acks from relevant
experts.
To use the new feature you have to add an F option to your binfmt_misc
configuration"
From the docs:
"The usual behaviour of binfmt_misc is to spawn the binary lazily when
the misc format file is invoked. However, this doesn't work very well
in the face of mount namespaces and changeroots, so the F mode opens
the binary as soon as the emulation is installed and uses the opened
image to spawn the emulator, meaning it is always available once
installed, regardless of how the environment changes"

In most cases, EPERM is returned on immutable inode, and there're only a
few places returning EACCES. I noticed this when running LTP on

Pull more xfs updates from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle, and
contains the new reverse block mapping feature for XFS.
Reverse mapping allows us to track the owner of a specific block on
disk precisely. It is implemented as a set of btrees (one per
allocation group) that track the owners of allocated extents.
Effectively it is a "used space tree" that is updated when we allocate
or free extents. i.e. it is coherent with the free space btrees we
already maintain and never overlaps with them.
This reverse mapping infrastructure is the building block of several
upcoming features - reflink, copy-on-write data, dedupe, online
metadata and data scrubbing, highly accurate bad sector/data loss
reporting to users, and significantly improved reconstruction of
damaged and corrupted filesystems. There's a lot of new stuff coming
along in the next couple of cycles,a nd it all builds in the rmap
infrastructure.
As such, it's a huge chunk of new code with new on-disk format
features and internal infrastructure. It warns at mount time as an
experimental feature and that it may eat data (as we do with all new
on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time kernel
with this code in it is released.
The new rmap enabled code regresses 3 xfstests - all are ENOSPC
related corner cases, one of which Darrick posted a fix for a few
hours ago. The other two are fixed by infrastructure that is part of
the upcoming reflink patchset. This new ENOSPC infrastructure
requires a on-disk format tweak required to keep mount times in
check - we need to keep an on-disk count of allocated rmapbt blocks so
we don't have to scan the entire btrees at mount time to count them.
This is currently being tested and will be part of the fixes sent in
the next week or two so users will not be exposed to this change"

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS for 4.8. Also includes is a
minor SSB cleanup as SSB code traditionally is merged through the MIPS
tree:
ATH25:
- MIPS: Add default configuration for ath25
Boot:
- For zboot, copy appended dtb to the end of the kernel
- store the appended dtb address in a variable
BPF:
- Fix off by one error in offset allocation
Cobalt code:
- Fix typos
Core code:
- debugfs_create_file returns NULL on error, so don't use IS_ERR for
testing for errors.
- Fix double locking issue in RM7000 S-cache code. This would only
affect RM7000 ARC systems on reboot.
- Fix page table corruption on THP permission changes.
- Use compat_sys_keyctl for 32 bit userspace on 64 bit kernels.
David says, there are no compatibility issues raised by this fix.
- Move some signal code around.
- Rewrite r4k count/compare clockevent device registration such that
min_delta_ticks/max_delta_ticks files are guaranteed to be
initialized.
- Only register r4k count/compare as clockevent device if we can
assume the clock to be constant.
- Fix MSA asm warnings in control reg accessors
- uasm and tlbex fixes and tweaking.
- Print segment physical address when EU=1.
- Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO.
