In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:
http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57
Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:
/home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator. Stop.
When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:
\# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
\# using basic dep data
This is because `tools/build/Build.include' prints these '\#'
characters:
printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
printf '\# using basic dep data\n\n' >> $(dot-target).cmd; \
This completes commit 9564a8cf42 ("Kbuild: fix # escaping in .cmd files
for future Make").

open a file by given inode, faking ->f_path. Use with shitloads
of caution - at the very least you'd damn better make sure that
some dentry alias of that inode is pinned down by the path in
question. Again, this is no general-purpose interface and I hope
it will eventually go away. Right now overlayfs wants something
like that, but nothing else should.
Any out-of-tree code with bright idea of using this one *will*
eventually get hurt, with zero notice and great delight on my part.
I refuse to use EXPORT_SYMBOL_GPL(), especially in situations when
it's really EXPORT_SYMBOL_DONT_USE_IT(), but don't take that export
as "you are welcome to use it".

For Synopsys DesignWare 8250 uart which version >= 4.00a, there's a
valid divisor latch fraction register. The fractional divisor width is
4bits ~ 6bits.
Now the preparation is done, it's easy to add the feature support.
This patch firstly tries to get the fractional divisor width during
probe, then setups dw specific get_divisor() and set_divisor() hook.

[Why]
When a dce100 asic was suspended, the clocks were not set to 0.
Upon resume, the new clock was compared to the existing clock,
they were found to be the same, and so the clock was not set.
This resulted in a pernicious blackscreen.
[How]
In atomic commit, check to see if there are any active pipes.
If no, set clocks to 0

The driver is expecting clock frequency in kHz, while SMU returns
the values in 10kHz, which causes the bandwidth validation to fail
4.18 has the faulty clock assignment in pp_to_dc_clock_levels_with_latency
only, which is only used by Vega. Make sure we multiply these values
by 10 here, as we do for other ASICs as powerplay assigned them
wrong. 4.19 has the proper fix in powerplay.

0d4b78b3d2 ("drm/i915/guc: Assert we have the doorbell before setting it up")
We have asserts in GuC doorbell related functions, which is a good thing.
Unfortunately, we were using those to check whether GuC FW is refusing
to allocate invalid doorbell - which makes the test fail.
Well, it would make the test WARN, except we fumbled cleanup ordering
and eat the BUG_ON instead.
Let's keep the asserts and use the internal implementation in the test.

of updates to the receive address register (RAR) table. Prior to this patch
I believe we may have been updating the table while entries were still

explicitly flushing writes to either the lower or upper portion of the

Parallel to FILE_CREATED, goes into ->f_mode instead of *opened.
NFS is a bit of a wart here - it doesn't have file at the point
where FILE_CREATED used to be set, so we need to propagate it
there (for now). IMA is another one (here and everywhere)...
Note that this needs do_dentry_open() to leave old bits in ->f_mode
alone - we want it to preserve FMODE_CREATED if it had been already
set (no other bit can be there).
