So the original intention of tsk_cpus_allowed() was to 'future-proof'
the field - but it's pretty ineffectual at that, because half of
the code uses ->cpus_allowed directly ...
Also, the wrapper makes the code longer than the original expression!
So just get rid of it. This also shrinks <linux/sched.h> a bit.

INPUT_PROP_BUTTONPAD is currently only set through the platform data.
The RMI4 header doc says that this property is there to force the
buttonpad property, so we also need to detect it by looking at
the exported buttons count.

Pull IDR rewrite from Matthew Wilcox:
"The most significant part of the following is the patch to rewrite the
IDR & IDA to be clients of the radix tree. But there's much more,
including an enhancement of the IDA to be significantly more space
efficient, an IDR & IDA test suite, some improvements to the IDR API
(and driver changes to take advantage of those improvements), several
improvements to the radix tree test suite and RCU annotations.
The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree
for most of the last cycle. Coupled with the IDR test suite, I feel
pretty confident that any remaining bugs are quite hard to hit. 0-day
did a great job of watching my git tree and pointing out problems; as
it hit them, I added new test-cases to be sure not to be caught the
same way twice"
Willy goes on to expand a bit on the IDR rewrite rationale:
"The radix tree and the IDR use very similar data structures.
Merging the two codebases lets us share the memory allocation pools,
and results in a net deletion of 500 lines of code. It also opens up
the possibility of exposing more of the features of the radix tree to
users of the IDR (and I have some interesting patches along those
lines waiting for 4.12)
It also shrinks the size of the 'struct idr' from 40 bytes to 24 which
will shrink a fair few data structures that embed an IDR"

Pull cgroup updates from Tejun Heo:
"Several noteworthy changes.
- Parav's rdma controller is finally merged. It is very straight
forward and can limit the abosolute numbers of common rdma
constructs used by different cgroups.
- kernel/cgroup.c got too chubby and disorganized. Created
kernel/cgroup/ subdirectory and moved all cgroup related files
under kernel/ there and reorganized the core code. This hurts for
backporting patches but was long overdue.
- cgroup v2 process listing reimplemented so that it no longer
depends on allocating a buffer large enough to cache the entire
result to sort and uniq the output. v2 has always mangled the sort
order to ensure that users don't depend on the sorted output, so
this shouldn't surprise anybody. This makes the pid listing
functions use the same iterators that are used internally, which
have to have the same iterating capabilities anyway.
- perf cgroup filtering now works automatically on cgroup v2. This
patch was posted a long time ago but somehow fell through the
cracks.
- misc fixes asnd documentation updates"

The test to see if VGA was already enabled is doing an unnecessary
second test from a register that may or may not have been initialized
to a valid value. Remove it.

This is used when the BMC isn't running any code and thus has
to be initialized by the host.
The code originates from Aspeed (Y.C. Chen) and has been cleaned
up for coding style purposes by BenH.

The function does more than initializing the DRAM and in turns
calls other functions to do the actual init. This will keeping
things more consistent with the upcoming AST2500 POST code.

There's a some duplication for what's essentially copies of
two loops, so factor it. The upcoming AST2500 POST code adds
more of them. Also cleanup return types for the test functions,
most of them return a boolean, some return a u32.

Some braces were missing causing an incorrect calculation.
Y.C. Chen from Aspeed provided me with the right formula
which I tested on AST2400 and 2500.
The MCLK isn't currently used by the driver (it will eventually
to filter modes) so the issue isn't catastrophic.
Also make the printed value a bit more meaningful

The ast driver configures a window to enable access into BMC
memory space in order to read some configuration registers.
If this window is disabled, which it can be from the BMC side,
the ast driver can't function.
Closing this window is a necessity for security if a machine's
host side and BMC side are controlled by different parties;
i.e. a cloud provider offering machines "bare metal".
A recent patch went in to try to check if that window is open
but it does so by trying to access the registers in question
and testing if the result is 0xffffffff.
This method will trigger a PCIe error when the window is closed
which on some systems will be fatal (it will trigger an EEH
for example on POWER which will take out the device).
This patch improves this in two ways:
- First, if the firmware has put properties in the device-tree
containing the relevant configuration information, we use these.
- Otherwise, a bit in one of the SCU scratch registers (which
are readable via the VGA register space and writeable by the BMC)
will indicate if the BMC has closed the window. This bit has been
defined by Y.C Chen from Aspeed.
If the window is closed and the configuration isn't available from
the device-tree, some sane defaults are used. Those defaults are
hopefully sufficient for standard video modes used on a server.

We already have the helper, we can convert the rest of the kernel
mechanically using:
git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

Apart from adding the helper function itself, the rest of the kernel is
converted mechanically using:
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/'
git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.
