Currently io_ticks is approximated by adding one at each start and end of
requests if jiffies counter has changed. This works perfectly for requests
shorter than a jiffy or if one of requests starts/ends at each jiffy.
If disk executes just one request at a time and they are longer than two
jiffies then only first and last jiffies will be accounted.
Fix is simple: at the end of request add up into io_ticks jiffies passed
since last update rather than just one jiffy.
Example: common HDD executes random read 4k requests around 12ms.
fio --name=test --filename=/dev/sdb --rw=randread --direct=1 --runtime=30 &
iostat -x 10 sdb
Note changes of iostat's "%util" 8,43% -> 99,99% before/after patch:
Before:
Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util
sdb 0,00 0,00 82,60 0,00 330,40 0,00 8,00 0,96 12,09 12,09 0,00 1,02 8,43
After:
Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util
sdb 0,00 0,00 82,50 0,00 330,00 0,00 8,00 1,00 12,10 12,10 0,00 12,12 99,99
Now io_ticks does not loose time between start and end of requests, but
for queue-depth > 1 some I/O time between adjacent starts might be lost.
For load estimation "%util" is not as useful as average queue length,
but it clearly shows how often disk queue is completely empty.

Call scsi_bios_ptable from scsi_partsize instead of requiring boilerplate
code in the callers. Also switch the calling convention to match that
of the ->bios_param instances calling this function, and use true/false
for the return value instead of the weird -1 convention.

The kernel documentation includes a brief section about genhd
capabilities, but it turns out that the only documented
capability (GENHD_FL_MEDIA_CHANGE_NOTIFY) isn't used any more.
This patch removes that flag, and documents the rest, based on my
understanding of the current uses of these flags in the kernel. The
documentation is kept in the header file, alongside the declarations,
in the hope that it will be kept up-to-date in future; the kernel
documentation is changed to include the documentation generated from
the header file.
Because the ultimate goal is to provide some end-user
documentation (or end-administrator documentation), the comments are
perhaps more user-oriented than might be expected. Since the values
are shown to users in hexadecimal, the documentation lists them in
hexadecimal, and the constant declarations are adjusted to match.

Pull ARM SoC fixes from Olof Johansson:
"We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.
Largest delta is due to a led-bl driver that is added -- there was a
miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.
Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing
for a while, so a few updates of that.
... and the usual collection of smaller fixes to various platforms"

The hierarchical topology with power-domain should be described through
child nodes, rather than as currently described in the PSCI root node. Fix
this by adding a patternProperties with a corresponding reference to the

the adjusted domain-idle-state DT binding.

This sentence does not make sense in the section about mandatory-y.
This seems to be a copy-paste mistake of commit fcc8487d477a ("uapi:
export all headers under uapi directories").
The correct description would be "The convention is to list one
mandatory-y per line ...".
I just removed it instead of fixing it. If such information is needed,
it could be commented in include/asm-generic/Kbuild and

When there was no parallelism (no top-level -j arg and a pre-1.7
sphinx-build), the argument passed would be empty ("") instead of just
being missing, which would (understandably) badly confuse sphinx-build.
Fix this by removing the quotes.

MPX was removed in commit 45fc24e89b7c ("x86/mpx: remove MPX from

There are several DT doc references that require manual fixes.

Pull arm64 fixes from Will Deacon:
"It's all straightforward apart from the changes to mmap()/mremap() in
relation to their handling of address arguments from userspace with
non-zero tag bits in the upper byte.
The change to brk() is necessary to fix a nasty user-visible
regression in malloc(), but we tightened up mmap() and mremap() at the
same time because they also allow the user to create virtual aliases
by accident. It's much less likely than brk() to matter in practice,
but enforcing the principle of "don't permit the creation of mappings
using tagged addresses" leads to a straightforward ABI without having
to worry about the "but what if a crazy program did foo?" aspect of
things.
Summary:
- Fix regression in malloc() caused by ignored address tags in brk()
- Add missing brackets around argument to untagged_addr() macro
- Fix clang build when using binutils assembler
- Fix silly typo in virtual memory map documentation"

Add append value operator "+=" support to bootconfig syntax.
With this operator, user can add new value to the key as
an entry of array instead of overwriting.
For example,
foo = bar
...
foo += baz
Then the key "foo" has "bar" and "baz" values as an array.

Currently, bootconfig adds a new value on the existing key to the tail of an
array. But this looks a bit confusing because an admin can easily rewrite
the original value in the same config file.
This rejects the following value re-definition.
key = value1
...
key = value2
You should rewrite value1 to value2 in this case.
