When converting the driver to use the devm_hwmon_device_register_with_info
API, the wrong register was selected when writing into inX_max attributes.
Fix it.

Add ADP-P PCH device ID and assign as ADL PCH if found. Previously we
would assign the DDC pin map based on the PCH, but it can also change
based on the CPU. From Bspec 20124: "The physical port to pin pair
mapping are defined in the Bspec per PCH. Mapping can further change
based on CPU Si used as CPU and PCH can be mixed and matched".

Aside from the hardware-managed PG0, XE_LPD has power wells 1-2 and
A-D. These power wells should be enabled/disabled according to the
following dependency tree (enable top to bottom, disable bottom to top):
PG0
|
--PG1--
/ \
PGA --PG2--
/ | \
PGB PGC PGD
PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the
bits that would have been PG 6-9 under the old scheme.
PWR_WELL_CTL_{DDI,AUX}'s bit indexing for DDI's A-C and TC1 is the same
as TGL, but DDI-D is placed at index 7 (bits 14 & 15).
v2:
- Squash in LPSP status patch from Uma since it's also a
powerwell-specific change.

XE_LPD has new AUX interrupt bits for DDI-D and DDI-E that take the
spots that were used by TC5/TC6 on Display12 platforms.
While we're at it, let's convert the bit definitions for all TGL+ aux
bits over to the modern REG_BIT() notation.
v2:
- Maintain bit order rather than logical order. (Lucas)
- Convert surrounding code to REG_BIT() notation. (Lucas)

A discussion around -Wundef showed that there were still a few boolean
Kconfigs where #if was used rather than #ifdef to guard different code.
Kconfig doesn't define boolean configs, which can result in -Wundef
warnings.
arch/x86/boot/compressed/Makefile resets the CFLAGS used for this
directory, and doesn't re-enable -Wundef as the top level Makefile does.
If re-added, with RANDOMIZE_BASE and X86_NEED_RELOCS disabled, the
following warnings are visible.
arch/x86/boot/compressed/misc.h:82:5: warning: 'CONFIG_RANDOMIZE_BASE'
is not defined, evaluates to 0 [-Wundef]
^
arch/x86/boot/compressed/misc.c:175:5: warning: 'CONFIG_X86_NEED_RELOCS'
is not defined, evaluates to 0 [-Wundef]
^
Simply fix these and re-enable this warning for this directory.

ACPI 6.4 introduced the "SpaLocationCookie" to the NFIT "System Physical
Address (SPA) Range Structure". The presence of that new field is
indicated by the ACPI_NFIT_LOCATION_COOKIE_VALID flag. Pre-ACPI-6.4
firmware implementations omit the flag and maintain the original size of
the structure.
Update the implementation to check that flag to determine the size
rather than the ACPI 6.4 compliant definition of 'struct
acpi_nfit_system_address' from the Linux ACPICA definitions.
Update the test infrastructure for the new expectations as well, i.e.
continue to emulate the ACPI 6.3 definition of that structure.
Without this fix the kernel fails to validate 'SPA' structures and this
leads to a crash in nfit_get_smbios_id() since that routine assumes that
SPAs are valid if it finds valid SMBIOS tables.
BUG: unable to handle page fault for address: ffffffffffffffa8

If the total number of commands queried through TPM2_CAP_COMMANDS is
different from that queried through TPM2_CC_GET_CAPABILITY, it indicates
an unknown error. In this case, an appropriate error code -EFAULT should
be returned. However, we currently do not explicitly assign this error
code to 'rc'. As a result, 0 was incorrectly returned.

Our code analyzer reported a double free bug.
In gen8_preallocate_top_level_pdp, pde and pde->pt.base are allocated
via alloc_pd(vm) with one reference. If pin_pt_dma() failed, pde->pt.base
is freed by i915_gem_object_put() with a reference dropped. Then free_pd
calls free_px() defined in intel_ppgtt.c, which calls i915_gem_object_put()
to put pde->pt.base again.
As pde->pt.base is protected by refcount, so the second put will not free
pde->pt.base actually. But, maybe it is better to remove the first put?

Gen2 tiles are 2KiB in size so i915_gem_object_get_tile_row_size()
can in fact return <4KiB, which leads to div-by-zero here.
Avoid that.
Not sure i915_gem_object_get_tile_row_size() is entirely
sane anyway since it doesn't account for the different tile
layouts on i8xx/i915...
I'm not able to hit this before commit 6846895fde05 ("drm/i915:
Replace PIN_NONFAULT with calls to PIN_NOEVICT") and it looks
like I also need to run recent version of Mesa. With those in

Reset the ns->file value to NULL also in the error case in
nvmet_file_ns_enable().
The ns->file variable points either to file object or contains the
error code after the filp_open() call. This can lead to following
problem:
When the user first setups an invalid file backend and tries to enable
the ns, it will fail. Then the user switches over to a bdev backend
and enables successfully the ns. The first received I/O will crash the
system because the IO backend is chosen based on the ns->file value:
static u16 nvmet_parse_io_cmd(struct nvmet_req *req)
{
[...]
if (req->ns->file)
return nvmet_file_parse_io_cmd(req);
return nvmet_bdev_parse_io_cmd(req);

Suppose we have 2 threads, the group-leader L and a sub-theread T,
both parked in ptrace_stop(). Debugger tries to resume both threads
and does
ptrace(PTRACE_CONT, T);
ptrace(PTRACE_CONT, L);
If the sub-thread T execs in between, the 2nd PTRACE_CONT doesn not
resume the old leader L, it resumes the post-exec thread T which was
actually now stopped in PTHREAD_EVENT_EXEC. In this case the
PTHREAD_EVENT_EXEC event is lost, and the tracer can't know that the
tracee changed its pid.
This patch makes ptrace() fail in this case until debugger does wait()
and consumes PTHREAD_EVENT_EXEC which reports old_pid. This affects all
ptrace requests except the "asynchronous" PTRACE_INTERRUPT/KILL.
The patch doesn't add the new PTRACE_ option to not complicate the API,
and I _hope_ this won't cause any noticeable regression:
- If debugger uses PTRACE_O_TRACEEXEC and the thread did an exec
and the tracer does a ptrace request without having consumed
the exec event, it's 100% sure that the thread the ptracer
thinks it is targeting does not exist anymore, or isn't the
same as the one it thinks it is targeting.
- To some degree this patch adds nothing new. In the scenario
above ptrace(L) can fail with -ESRCH if it is called after the
execing sub-thread wakes the leader up and before it "steals"
the leader's pid.

BFQ may merge a new bfq_queue, stably, with the last bfq_queue
created. In particular, BFQ first waits a little bit for some I/O to
flow inside the new queue, say Q2, if this is needed to understand
whether it is better or worse to merge Q2 with the last queue created,
say Q1. This delayed stable merge is performed by assigning
bic->stable_merge_bfqq = Q1, for the bic associated with Q1.
Yet, while waiting for some I/O to flow in Q2, a non-stable queue
merge of Q2 with Q1 may happen, causing the bic previously associated
with Q2 to be associated with exactly Q1 (bic->bfqq = Q1). After that,
Q2 and Q1 may happen to be split, and, in the split, Q1 may happen to
be recycled as a non-shared bfq_queue. In that case, Q1 may then
happen to undergo a stable merge with the bfq_queue pointed by
bic->stable_merge_bfqq. Yet bic->stable_merge_bfqq still points to
Q1. So Q1 would be merged with itself.
This commit fixes this error by intercepting this situation, and
canceling the schedule of the stable merge.

We currently don't have any filesystems that support idmapped mounts
which are mountable inside a user namespace. That was a deliberate
decision for now as a userns root can just mount the filesystem
themselves. So enforce this restriction explicitly until there's a real
use-case for this. This way we can notice it and will have a chance to
adapt and audit our translation helpers and fstests appropriately if we
need to support such filesystems.

When hotplugging CPUs on Tegra186 and Tegra194 errors such as the
following are seen ...
IRQ63: set affinity failed(-22).
IRQ65: set affinity failed(-22).
IRQ66: set affinity failed(-22).
IRQ67: set affinity failed(-22).
Looking at the /proc/interrupts the above are all interrupts associated
with GPIOs. The reason why these error messages occur is because there
is no 'parent_data' associated with any of the GPIO interrupts and so
tegra186_irq_set_affinity() simply returns -EINVAL.
To understand why there is no 'parent_data' it is first necessary to
understand that in addition to the GPIO interrupts being routed to the
interrupt controller (GIC), the interrupts for some GPIOs are also
routed to the Tegra Power Management Controller (PMC) to wake up the
system from low power states. In order to configure GPIO events as
wake events in the PMC, the PMC is configured as IRQ parent domain
for the GPIO IRQ domain. Originally the GIC was the IRQ parent domain
of the PMC and although this was working, this started causing issues
once commit 64a267e9a41c ("irqchip/gic: Configure SGIs as standard
interrupts") was added, because technically, the GIC is not a parent
of the PMC. Commit c351ab7bf2a5 ("soc/tegra: pmc: Don't create fake
interrupt hierarchy levels") fixed this by severing the IRQ domain
hierarchy for the Tegra GPIOs and hence, there may be no IRQ parent
domain for the GPIOs.
The GPIO controllers on Tegra186 and Tegra194 have either one or six
interrupt lines to the interrupt controller. For GPIO controllers with
six interrupts, the mapping of the GPIO interrupt to the controller
interrupt is configurable within the GPIO controller. Currently a
default mapping is used, however, it could be possible to use the
set affinity callback for the Tegra186 GPIO driver to do something a
bit more interesting. Currently, because interrupts for all GPIOs are
have the same mapping and any attempts to configure the affinity for
a given GPIO can conflict with another that shares the same IRQ, for
now it is simpler to just remove set affinity support and this avoids
the above warnings being seen.

It's very confusing for userspace to have to deal with inconsistencies
here, and some drivers screwed this up a bit. Most just ommitted the
format list when they meant to say that only linear modifier is
allowed, but some also meant that only implied modifiers are
acceptable (because actually none of the planes registered supported
modifiers).
Now that this is all done consistently across all drivers, document
the rules and enforce it in the drm core.
v2:
- Make the capability a link (Simon)
- Note that all is lost before 5.1.
v3:
- Use drm_WARN_ON (Lyude)

The proper headers have now landed in include/uapi/drm/i915_drm.h, so we
can drop i915_gem_lmem.h and instead just reference the real headers for
pulling in the kernel doc.

In commit:
9fe1f127b913 ("sched/fair: Merge select_idle_core/cpu()")
in select_idle_cpu(), we check if an idle core is present in the LLC
of the target CPU via the flag "has_idle_cores". We look for the idle
core in select_idle_cores(). If select_idle_cores() isn't able to find
an idle core/CPU, we need to unset the has_idle_cores flag in the LLC
of the target to prevent other CPUs from going down this route.
However, the current code is unsetting it in the LLC of the current
CPU instead of the target CPU. This patch fixes this issue.

The final solution can be migrating blocks to form a section-aligned file
internally. Meanwhile, let's ask users to do that when preparing the swap
file initially like:
1) create()
2) ioctl(F2FS_IOC_SET_PIN_FILE)
3) fallocate()
