992cf65674 Input: iqs7222 - add support for IQS7222D v1.1 and v1.2
The vendor has introduced two new revisions with slightly different
memory maps; update the driver to support them.

1a8ec63b2b io_uring: fix io_queue_proc modifying req->flags
With multiple poll entries __io_queue_proc() might be running in
parallel with poll handlers and possibly task_work, we should not be
carelessly modifying req->flags there. io_poll_double_prepare() handles
a similar case with locking but it's much easier to move it into
__io_arm_poll_handler().

6d7241b0e9 drm/i915: Streamline eDP handling in icl_combo_phy_aux_power_well_enable()
Drop the pointless phy/port detour from the eDP handling
in icl_combo_phy_aux_power_well_enable(). We can just directly
consult the dig_port and determine whether it's eDP or not.

This also removes the assumption that port==phy, although that is
always trued on ICL, so it wasn't really doing any harm.

59b806d06f drm/i915: Use pw_idx to derive PHY for ICL_LANE_ENABLE_AUX override
We don't actually know whether we should be picking the PHY
simply based on the AUX_CH/power well, or based on the VBT
defined AUX_CH->DDI->PHY relationship. At the moment we are
doing the former for the ANAOVRD workaround, and the latter
for the ICL_LANE_ENABLE_AUX override. Windows seems to use the
first approach for everything. So let's unify this to follow
that same approach for both.

Eventually we should try to figure out  which is actually
correct, or whether any of this even matters (ie. whether there
are any real machines where the DDI and its AUX_CH do not match
1:1).

Note that this also changes the behaviour if we do end up
poking an AUX power well not associated with any port (as
per VBT). Previously we would have skipped the PHY register
write, but now we always write it.

3f003fda98 hwmon: (amc6821) add of_match table
Add of_match table for "ti,amc6821" compatible string.
This fixes automatic driver loading by userspace when using device-tree,
and if built as a module like major linux distributions do.

While devices probe just fine with i2c_device_id table, userspace can't
match the "ti,amc6821" compatible string from dt with the plain
"amc6821" device id. As a result, the kernel module can not be loaded.

FEAT_FPMR defines a new EL0 accessible register FPMR use to configure the
FP8 related features added to the architecture at the same time. Detect
support for this register and context switch it for EL0 when present.

Due to the sharing of responsibility for saving floating point state
between the host kernel and KVM FP8 support is not yet implemented in KVM
and a stub similar to that used for SVCR is provided for FPMR in order to
avoid bisection issues. To make it easier to share host state with the
hypervisor we store FPMR as a hardened usercopy field in uw (along with
some padding).

6764ee4718 drm/i915/dsb: Always set DSB_SKIP_WAITS_EN
Bspec asks us to always set the DSB_SKIP_WAITS_EN bit in
DSB_CHICKEN. This seems to instruct DSB to skip vblank and
scanline waits when PSR is entered.

I don't think we have any cases currently where we would want
to enter PSR while DSB is waiting for something, but let's
set the bit anyway to align with Bspec's wishes.

41429d9b68 drm/i915/dsb: Fix DSB vblank waits when using VRR
Looks like the undelayed vblank gets signalled exactly when
the active period ends. That is a problem for DSB+VRR when
we are already in vblank and expect DSB to start executing
as soon as we send the push. Instead of starting, the DSB
just keeps on waiting for the undelayed vblank which won't
signal until the end of the next frame's active period,
which is far too late.

The end result is that DSB won't have even started
executing by the time the flips/etc. have completed.
We then wait for an extra 1ms, after which we terminate
the DSB and report a timeout:
[drm] *ERROR* [CRTC:80:pipe A] DSB 0 timed out waiting for idle (current head=0xfedf4000, head=0x0, tail=0x1080)

To fix this let's configure DSB to use the so called VRR
"safe window" instead of the undelayed vblank to trigger
the DSB vblank logic, when VRR is enabled.

810e4519a1 drm/i915/vrr: Generate VRR "safe window" for DSB
Looks like TRANS_CHICKEN bit 31 means something totally different
depending on the platform:
TGL: generate VRR "safe window" for DSB
ADL/DG2: make TRANS_SET_CONTEXT_LATENCY effective with VRR

So far we've only set this on ADL/DG2, but when using DSB+VRR
we also need to set it on TGL.

And a quick test on MTL says it doesn't need this bit for either
of those purposes, even though it's still documented as valid
in bspec.

fa9e3139e6 s390/tools: handle rela R_390_GOTPCDBL/R_390_GOTOFF64
lkp test robot reported unhandled relocation type: R_390_GOTPCDBL, when
kernel is built with -fno-PIE. relocs tool reads vmlinux and handles
absolute relocations.  PC relative relocs doesn't need adjustment.

Also, the R_390_GOTPCDBL/R_390_GOTOFF64 relocations are present
currently only when KASAN is enabled.

The following program can create a R_390_GOTPCDBL/R_390_GOTOFF64 reloc
(with fPIE/fPIC).

void funcb(int *b) {
  *b = *b + 100;
}

void gen_gotoff(void)
{
  int b = 10;
  funcb (&b);
}

gcc -c sample.c -fPIC -fsanitize=kernel-address --param asan-stack=1

The above example (built with -fPIC) was linked to one of the
built-in.a (built with -fno-PIE) and checked for correctness with kaslr
enabled. Both the relocs turns out relative and can be skipped.

It is not safe to unbind and then rebind a subdevice in the rcar-vin
pipeline. Depending on what subdevice and in what order a device is
rebound the rcar-vin driver can misbehave.

Until this can be solved suppress the files in sysfs which allows for
this. This is in line with what is done for other subdevices exclusively
use with the rcar-vin pipeline, e.g. rcar-csi2.

First of all, last_cs_index_mask should be aligned with the original
cs_index_mask, which is 16-bit (for now) wide. Use the same pattern
for the last_cs_index_mask.

Second, last_cs can be negative and since 'char' is equal to 'unsigned
char' in the kernel, it's incorrect, strictly speaking, to assign
signed number to it. Use s8 type as it's done for *_native_cs ones.

With this change, regroup a bit the ordering to avoid too much memory
