An empty flush doesn't have a payload, so it should never be looked at
when considering to possibly requeue a bio for the case when a reshape

When `CONFIG_DEBUG_FS` is disabled, nmk_gpio_dbg_show_one() is an
empty dummy function; this however triggers a `-Wmissing-prototypes`
warning and later a linker error because the function is also used by
drivers/pinctrl/nomadik/pinctrl-nomadik.c, therefore it needs to be
non-static.
To allow both sources to access this dummy function, this patch moves
it to the header, adding the `#ifdef CONFIG_DEBUG_FS` there as well.

Using BUG_ON() is discouraged and also the check wasn't done early
enough to prevent an out of bounds access. Check earlier and return

The current code only prints PKGC-10 residency when the PKGC-10
is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we
also need to know other PKGC residency counters to better triage issues.
Ex:
1. When system is stuck in PC2, it can be caused short LTR from device.
2. When system is stuck in PC8, it can be caused by display engine.
To better triage issues, all PKGC residency are needed when issues happen.
Example log:
CPU did not enter Package C10!!! (Package C10 cnt=0x0)
Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724
Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0
Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0
Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0
Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0
Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0
Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0
With this log, we can know whether it's a stuck PC2 issue, and we can
check whether the short LTR from device causes the issue.

AAEON PICO-TGU4 board doesn't have any LED but there are bogus LED
controls under /sys/class/leds:
$ ls /sys/class/leds
asus::kbd_backlight asus::lightbar platform::micmute
The reason is that the ~0 read from asus_wmi_get_devstate() is treated
as a valid state, in truth it means the device is absent.
So filter out ~0 read to prevent bogus LED controls being created.

Pointer item is checked fo NULL at mlxreg_hotplug_work_helper() and then
it is dereferenced to produce dev_err().
This pointer is also dereferenced before calling this function and should
never be NULL except some piece of hardware is broken as it is said in
the comment before the check. So, this check can be safely removed.

For family 1AH, certain PMF features have been enhanced - leading to a
newer APMF (AMD PMF) spec (BIOS and PMF driver interface) called v2.
This information would be fed into the if_version field of the
verify_interface method of the APMF call from the BIOS.
Use this information to store the version number to differentiate
between v1 or v2 and also store the information into the PMF private
data structure, as this information would be required for further code
branching to support the latest silicon.

For the Bay Trail or Cherry Trail SoC to enter the S0i3 power-level
at s2idle suspend requires most of the hw-blocks / devices in the SoC
to be in D3 when entering s2idle suspend.
If some devices are not in D3 then the SoC will stay in a higher
power state, consuming much more power from the battery then in S0i3.
Use the new acpi_s2idle_dev_ops and acpi_register_lps0_dev()
functionality to register a new s2idle check function which checks that
all hardware blocks in the South complex (controlled by the PMC)
are in a state that allows the SoC to enter S0i3 and prints an error
message for any device in D0.
Some blocks are not used on lower-featured versions of the SoC and
these blocks will always report being in D0 on SoCs were they are
not used. A false-positive mask is used to identify these blocks
and for blocks in this mask the error is turned into a debug message
to avoid false-positive error messages.
Note the pmc_atom code is enabled by CONFIG_X86_INTEL_LPSS which
already depends on ACPI.

This is a preparation patch to extend the S0i3 readiness checks

clocks are off on suspend entry.
Note these are added to include/linux/platform_data/x86/pmc_atom.h rather
then to include/linux/platform_data/x86/clk-pmc-atom.h because the former

The whitelist-based approach for preventing older WMI drivers from
being instantiated multiple times has many drawbacks:
- uses cannot see all available WMI devices (if not whitelisted)
- whitelisting a WMI driver requires changes in the WMI driver core
- maintenance burden for driver and subsystem developers
Since the WMI driver core already takes care that older WMI drivers
are not being instantiated multiple times, remove the now redundant
whitelist.

Many older WMI drivers cannot be instantiated multiple times for
two reasons:
- they are using the legacy GUID-based WMI API
- they are singletons (with global state)
Prevent such WMI drivers from binding to WMI devices with a duplicated
GUID, as this would mean that the WMI driver will be instantiated at
least two times (one for the original GUID and one for the duplicated
GUID).
WMI drivers which can be instantiated multiple times can signal this
by setting a flag inside struct wmi_driver.

When matching a WMI device to a GUID used by the legacy GUID-based
API, devices with a duplicated GUID should be ignored.
Add an additional WMI device flag signaling that the GUID used by
the WMI device is also used by another WMI device. Ignore such
devices inside the match functions used by the legacy GUID-based API.

There's a new conflict with Linus's upstream tree, because
in the following merge conflict resolution in <asm/coco.h>:
38b334fc767e Merge tag 'x86_sev_for_v6.9_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Linus has resolved the conflicting placement of 'cc_mask' better
than the original commit:
1c811d403afd x86/sev: Fix position dependent variable references in startup code
... which was also done by an internal merge resolution:
2e5fc4786b7a Merge branch 'x86/sev' into x86/boot, to resolve conflicts and to pick up dependent tree
But Linus is right in 38b334fc767e, the 'cc_mask' declaration is sufficient
within the #ifdef CONFIG_ARCH_HAS_CC_PLATFORM block.
So instead of forcing Linus to do the same resolution again, merge in Linus's
tree and follow his conflict resolution.

The i801 and designware drivers received most of the changes,
including refactorings and some additions.
Recovery changes for the iMX and iMX-LPI2C are now utilizing the
generic i2c support.
The Cadence driver now supports system suspend and resume.
The hisi, mpc, sh_mobile, and npcm drivers have undergone some
cleanups and improvements. Meanwhile, Uwe continues his work on
converting the "remove" callback to become a void function.
The pca954x mux driver now supports additional configurations,
such as isolating faulty channels and flushing stuck buses, among
others.
Support has been added for Renesas r8a779h0, i.MX95 LPI2C, and
Microchip sam9x7. Meanwhile, Geert lays the groundwork for the
upcoming R-Car Gen4.

Pull EDAC updates from Borislav Petkov:
- Add a FRU (Field Replaceable Unit) memory poison manager which
collects and manages previously encountered hw errors in order to
save them to persistent storage across reboots. Previously recorded
errors are "replayed" upon reboot in order to poison memory which has
caused said errors in the past.
The main use case is stacked, on-chip memory which cannot simply be
replaced so poisoning faulty areas of it and thus making them
inaccessible is the only strategy to prolong its lifetime.
- Add an AMD address translation library glue which converts the
reported addresses of hw errors into system physical addresses in
order to be used by other subsystems like memory failure, for
example. Add support for MI300 accelerators to that library.
- igen6: Add support for Alder Lake-N SoC

pull-request: bpf-next 2024-03-11
We've added 59 non-merge commits during the last 9 day(s) which contain
a total of 88 files changed, 4181 insertions(+), 590 deletions(-).
The main changes are:
1) Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
VM_SPARSE kind and vm_area_[un]map_pages to be used in bpf_arena,
from Alexei.
2) Introduce bpf_arena which is sparse shared memory region between bpf
program and user space where structures inside the arena can have
pointers to other areas of the arena, and pointers work seamlessly for
both user-space programs and bpf programs, from Alexei and Andrii.
3) Introduce may_goto instruction that is a contract between the verifier
and the program. The verifier allows the program to loop assuming it's
behaving well, but reserves the right to terminate it, from Alexei.
4) Use IETF format for field definitions in the BPF standard
document, from Dave.
5) Extend struct_ops libbpf APIs to allow specify version suffixes for
stuct_ops map types, share the same BPF program between several map
definitions, and other improvements, from Eduard.
6) Enable struct_ops support for more than one page in trampolines,
from Kui-Feng.
7) Support kCFI + BPF on riscv64, from Puranjay.
8) Use bpf_prog_pack for arm64 bpf trampoline, from Puranjay.
9) Fix roundup_pow_of_two undefined behavior on 32-bit archs, from Toke.

Pull x86 SEV updates from Borislav Petkov:
- Add the x86 part of the SEV-SNP host support.
This will allow the kernel to be used as a KVM hypervisor capable of
running SNP (Secure Nested Paging) guests. Roughly speaking, SEV-SNP
is the ultimate goal of the AMD confidential computing side,
providing the most comprehensive confidential computing environment
up to date.
This is the x86 part and there is a KVM part which did not get ready
in time for the merge window so latter will be forthcoming in the
next cycle.

order to allow building the kernel with clang and -fPIE/-fPIC and
-mcmodel=kernel

Commit 3e2f544dd8a33 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of in this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Remove the allocation in the vxlan driver and leverage the network
core allocation instead.
