This adds support for the Sony Xperia Loire/SmartLoire platform
with a base configuration that is common across all of the
devices that are based on this project.
Also adds a base DT configuration for the Xperia X and Xperia
X Compact (respectively, Suzu and Kugo) which is valid for both
their RoW (single-sim), DSDS (dual-sim) and other regional
variants of these two smartphones, that makes us able to boot
to a UART console.
Please note that, currently, the APC0/1 (cluster 0/1) vregs
are set to a safe voltage in order to ensure boot stability
until a proper solution for CPU DVFS scaling lands.

This commit adds device trees for MSM8956 and MSM8976 SoCs.
They are *almost* identical, with minor differences, such as
MSM8956 having two A72 cores less.
However, there is a bug in Sony Loire bootloader that requires presence
of all 8 cores in the cpu{} node, so these will not be deleted.

When adding support for the DisplayPort part of the QMP PHY the binding
(and devicetree parser) for the (USB) child node was simply reused and
this has lead to some confusion.
The third DP register region is really the DP_PHY region, not "PCS" as
the binding claims, and lie at offset 0x2a00 (not 0x2c00).
Similarly, there likely are no "RX", "RX2" or "PCS_MISC" regions as
there are for the USB part of the PHY (and in any case the Linux driver
does not use them).
Note that the sixth "PCS_MISC" region is not even in the binding.

When the NFSv4 state manager recovers state after a server restart, it
reports that locks have been lost if it finds any lock state for which
recovery hasn't been successful. i.e. any for which
NFS_LOCK_INITIALIZED is not set.
However it only tries to recover locks that are still linked to
inode->i_flctx. So if a lock has been removed from inode->i_flctx, but
the state for that lock has not yet been destroyed, then a spurious
warning results.
nfs4_proc_unlck() calls locks_lock_inode_wait() - which removes the lock
from ->i_flctx - before sending the unlock request to the server and
before the final nfs4_put_lock_state() is called. This allows a window
in which a spurious warning can be produced.
So add a new flag NFS_LOCK_UNLOCKING which is set once the decision has
been made to unlock the lock. This will prevent it from triggering any
warning.

If a framebuffer flush fails the driver will do one retry by requeing the
worker. Currently the worker is used even for synchronous flushing, but a
later patch will inline it, so this needs to change. Thinking about how to
solve this I came to the conclusion that this retry mechanism was a fix
for a problem that was only in the mind of the developer (me) and not
something that solved a real problem.
So let's remove this for now and revisit later should it become necessary.

Get rid of private "nmi_save_areas" slab cache. The only reason this was
introduced years ago was that with some slab debugging options allocations
would only guarantee a minimum alignment of ARCH_KMALLOC_MINALIGN, which
was eight bytes back then. This is not sufficient for the extended machine
check save area.
However since commit 59bb47985c ("mm, sl[aou]b: guarantee natural
alignment for kmalloc(power-of-two)") kmalloc guarantees a power-of-two
alignment even with debugging options enabled.
Therefore the private slab cache can be removed.

If a machine check happens in kernel mode, and the machine check
interruption code indicates that e.g. vector register contents in the
machine check area are not valid, the logic is to kill current.
The idea behind this was that if within kernel context vector
registers are not used then it is sufficient to kill the current user
space process to avoid that it continues with potentially corrupt
register contents. This however does not necessarily work, since the
current code does not take into account that a machine check can also
happen when a kernel thread is running (= no user space context), and
in addition there is no way to distinguish between the "previous" and
"next" user process task, if the machine check happens when a task
switch happens.
Given that machine checks with invalid saved register contents in the
machine check save area are extremely rare, simplify the logic: if
register contents are invalid and the previous context was kernel
mode, stop the whole machine. If the previous context was user mode,
kill the corresponding task.

The vector instruction macros can also be used in inline assemblies. For
this the magic
asm(".include \"asm/vx-insn.h\"\n");
must be added to C files in order to avoid that the pre-processor
eliminates the __ASSEMBLY__ guarded macros. This however comes with the
problem that changes to asm/vx-insn.h do not cause a recompile of C files
which have only this magic statement instead of a proper include statement.
This can be observed with the arch/s390/kernel/fpu.c file.
In order to fix this problem and also to avoid that the include must
be specified twice, add a wrapper include header file which will do
all necessary steps.
This way only the vx-insn.h header file needs to be included and changes to
the new vx-insn-asm.h header file cause a recompile of all dependent files
like it should.

We already fallback to a dummy BO with no backing store when we
allocate GDS,GWS and OA resources and to GTT when we allocate VRAM.
Drop all those workarounds and generalize this for GTT as well. This
fixes ENOMEM issues with runaway applications which try to allocate/free
GTT in a loop and are otherwise only limited by the CPU speed.
The CS will wait for the cleanup of freed up BOs to satisfy the
various domain specific limits and so effectively throttle those
buggy applications down to a sane allocation behavior again.
