ASoC: Intel: Work around to fix HW D3 potential crash issue
When using clock gatings to save power, there are some known issues:
1. core clock gating (DCLCGE) must be disabled during D0 and D3 entry
and updating SRAM banks (VDRTCTL0).
2. DSP trunk clock gating (DTCGE) can cause FW crashes, disable it in D0.
To align with the new W/A flow from FW team, we must set VDRTCTL0.D3PGD
to 1 (D3 power gating disabled) at first startup and keep it all the time.
ADSP will be in D0 on first boot by BIOS part of WA. Required delays must
be preserved (waiting for HW to stabilize, after enabling CCG, changing
SRAM PG, D3PG).
D3->D0:
1. Disable core clock gating (VDRTCTL2.DCLCGE = 0)
2. Enable other CG apart from DTCG and DCLCG (VDRTCTL2. DCLCGE and DTCGE = 0)
3. Disable D3PG (VDRTCTL0.D3PGD = 1)
4. Power up necessary SRAM and wait at least for 18 clock cycles for every
bank you have powered up
5. Set D0 state(PMCS.PS = 0), wait for HW
6. Restore MCLK (clkctl.smos, disabled in D3 entry point 4)
7. Stall and reset core, set CSR
8. Enable core clock gating (VDRTCTL2.DCLCGE = 1), delay 50 us
9. Unreset core
10.Load FW, configure PLL and other necessary things
11.Unstall core
Changing SRAM PG during D0:
1. Disable core clock gating (VDRTCTL2.DCLCGE = 0)
2. Set PG mask
3. Wait at least for 18 clock cycles for every bank you have powered up
4. Enable core clock gating, delay 50 us
D0->D3:
1. Disable core clock gating (DCLCGE = 0)
2. Stall and reset core
3. Power down entire SRAM and wait at least for 18 clock cycles for every bank
(Enable SRAM PG (ISRAMPGE = 0x3FF, DSRAMPGE = 0xFFFFF, D3SRAMPGD = 0), remember
about preserving VDRTCTL0.D3PGD = 1)
4. Shutdown PLL, disable MCLK(clkctl.smos = 0), Enable DTCG to save power

"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...
For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.
The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"

sparc64: Do not define thread fpregs save area as zero-length array.
This breaks the stack end corruption detection facility.
What that facility does it write a magic value to "end_of_stack()"
and checking to see if it gets overwritten.
"end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
the beginning of the FPU register save area.
So once the user uses the FPU, the magic value is overwritten and the
debug checks trigger.
Fix this by making the size explicit.
Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
are limited to 7 levels of FPU state saves. So each FPU register set
is 256 bytes, allocate 256 * 7 for the fpregs area.

sparc64: Fix corrupted thread fault code.
Every path that ends up at do_sparc64_fault() must install a valid
FAULT_CODE_* bitmask in the per-thread fault code byte.
Two paths leading to the label winfix_trampoline (which expects the
FAULT_CODE_* mask in register %g4) were not doing so:
1) For pre-hypervisor TLB protection violation traps, if we took
the 'winfix_trampoline' path we wouldn't have %g4 initialized
with the FAULT_CODE_* value yet. Resulting in using the
TLB_TAG_ACCESS register address value instead.
2) In the TSB miss path, when we notice that we are going to use a
hugepage mapping, but we haven't allocated the hugepage TSB yet, we
still have to take the window fixup case into consideration and
in that particular path we leave %g4 not setup properly.
Errors on this sort were largely invisible previously, but after
commit
4ccb9272892c33ef1c19a783cfa87103b30c2784 ("sparc64: sun4v TLB
error power off events") we now have a fault_code mask bit
(FAULT_CODE_BAD_RA) that triggers due to this bug.
FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS
(see #1 above) and thus we get seemingly random bus errors triggered
for user processes.

MAINTAINERS: Become the docs maintainer
It seems it's my turn to be the documentation maintainer for a bit. My
plan is to work to ensure that docs patches don't fall through the cracks;
I assume most changes will continue to flow through subsystem-specific
trees.

x86,kvm,vmx: Preserve CR4 across VM entry
CR4 isn't constant; at least the TSD and PCE bits can vary.
TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
like it's correct.
This adds a branch and a read from cr4 to each vm entry. Because it is
extremely likely that consecutive entries into the same vcpu will have
the same host cr4 value, this fixes up the vmcs instead of restoring cr4
after the fact. A subsequent patch will add a kernel-wide cr4 shadow,
reducing the overhead in the common case to just two memory reads and a
branch.

ipv6: fix a potential use after free in sit.c
pskb_may_pull() maybe change skb->data and make iph pointer oboslete,
fix it by geting ip header length directly.
Fixes:
