28980db947 EDAC/amd64: Shut up an -Werror,-Wsometimes-uninitialized clang false positive
Reportedly, clang cannot do interprocedural analysis:

  https://lore.kernel.org/r/20230213-amd64_edac-wsometimes-uninitialized-v1-1-5bde32b89e02@kernel.org

and see that those arguments won't be used uninitialized.

So, yeah, the code's fine even without this. Normally, such a "fix"
won't be applied but that warning gets automatically enabled in -Wall
builds and when CONFIG_WERROR is set in allmodconfig builds, the build
fails.

So shut it up with a minimal fix as this code will see more
reorganization very soon.

d125d1349a alarmtimer: Prevent starvation by small intervals and SIG_IGN
syzbot reported a RCU stall which is caused by setting up an alarmtimer
with a very small interval and ignoring the signal. The reproducer arms the
alarm timer with a relative expiry of 8ns and an interval of 9ns. Not a
problem per se, but that's an issue when the signal is ignored because then
the timer is immediately rearmed because there is no way to delay that
rearming to the signal delivery path.  See posix_timer_fn() and commit
58229a1899 ("posix-timers: Prevent softirq starvation by small intervals
and SIG_IGN") for details.

The reproducer does not set SIG_IGN explicitely, but it sets up the timers
signal with SIGCONT. That has the same effect as explicitely setting
SIG_IGN for a signal as SIGCONT is ignored if there is no handler set and
the task is not ptraced.

The log clearly shows that:

   [pid  5102] --- SIGCONT {si_signo=SIGCONT, si_code=SI_TIMER, si_timerid=0, si_overrun=316014, si_int=0, si_ptr=NULL} ---

It works because the tasks are traced and therefore the signal is queued so
the tracer can see it, which delays the restart of the timer to the signal
delivery path. But then the tracer is killed:

   [pid  5087] kill(-5102, SIGKILL <unfinished ...>
   ...
   ./strace-static-x86_64: Process 5107 detached

and after it's gone the stall can be observed:

   syzkaller login: [   79.439102][    C0] hrtimer: interrupt took 68471 ns
   [  184.460538][    C1] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:

   [  184.658237][    C1] rcu: Stack dump where RCU GP kthread last ran:
   [  184.664574][    C1] Sending NMI from CPU 1 to CPUs 0:
   [  184.669821][    C0] NMI backtrace for cpu 0
   [  184.669831][    C0] CPU: 0 PID: 5108 Comm: syz-executor192 Not tainted 6.2.0-rc6-next-20230203-syzkaller #0
   ...

   [  184.670045][    C0]  alarmtimer_fired+0x327/0x670

posix_timer_fn() prevents that by checking whether the interval for
timers which have the signal ignored is smaller than a jiffie and
artifically delay it by shifting the next expiry out by a jiffie. That's
accurate vs. the overrun accounting, but slightly inaccurate
vs. timer_gettimer(2).

The comment in that function says what needs to be done and there was a fix
available for the regular userspace induced SIG_IGN mechanism, but that did
not work due to the implicit ignore for SIGCONT and similar signals. This
needs to be worked on, but for now the only available workaround is to do
exactly what posix_timer_fn() does:

Increase the interval of self-rearming timers, which have their signal
ignored, to at least a jiffie.

Interestingly this has been fixed before via commit ff86bf0c65
("alarmtimer: Rate limit periodic intervals") already, but that fix got
lost in a later rework.

f9f57da2c2 x86/mtrr: Revert 90b926e68f ("x86/pat: Fix pat_x_mtrr_type() for MTRR disabled case")
Commit

  90b926e68f ("x86/pat: Fix pat_x_mtrr_type() for MTRR disabled case")

broke the use case of running Xen dom0 kernels on machines with an
external disk enclosure attached via USB, see Link tag.

What this commit was originally fixing - SEV-SNP guests on Hyper-V - is
a more specialized situation which has other issues at the moment anyway
so reverting this now and addressing the issue properly later is the
prudent thing to do.

So revert it in time for the 6.2 proper release.

389de9c5a6 dt-bindings: cpufreq: qcom-cpufreq-nvmem: make cpr bindings optional
The qcom-cpufreq-nvmem driver supports 2 kind of devices:
- pre-cpr that doesn't have power-domains and base everything on nvmem
  cells and multiple named microvolt bindings.
  Doesn't need required-opp binding in the opp nodes as they are only
  used for genpd based devices.
- cpr-based that require power-domain in the cpu nodes and use various
  source to decide the correct voltage and freq
  Require required-opp binding since they need to be linked to the
  related opp-level.

When the schema was introduced, it was wrongly set to always require these
binding but this is not the case for pre-cpr devices.

4562c65ec8 net: stmmac: fix order of dwmac5 FlexPPS parametrization sequence
So far changing the period by just setting new period values while
running did not work.

The order as indicated by the publicly available reference manual of the i.MX8MP [1]
indicates a sequence:

 * initiate the programming sequence
 * set the values for PPS period and start time
 * start the pulse train generation.

This is currently not used in dwmac5_flex_pps_config(), which instead does:

 * initiate the programming sequence and immediately start the pulse train generation
 * set the values for PPS period and start time

This caused the period values written not to take effect until the FlexPPS output was
disabled and re-enabled again.

This patch fix the order and allows the period to be set immediately.

ead089577e ata: libata-core: Disable READ LOG DMA EXT for Samsung MZ7LH
Samsung MZ7LH drives are spewing messages like this in to dmesg with AMD
SATA controllers:

ata1.00: exception Emask 0x0 SAct 0x7e0000 SErr 0x0 action 0x6 frozen
ata1.00: failed command: SEND FPDMA QUEUED

Since this was seen previously with SSD 840 EVO drives in
https://bugzilla.kernel.org/show_bug.cgi?id=203475 let's add the same
fix for these drives as the EVOs have, since they likely have very
similar firmwares.

On JZ4760 and JZ4760B, SD cards fail to run if the maximum clock
rate is set to 50 MHz, even though the controller officially does
support it.

Until the actual bug is found and fixed, limit the maximum clock rate to

If mmc_add_host() fails, it doesn't need to call mmc_remove_host(),
or it will cause null-ptr-deref, because of deleting a not added
device in mmc_remove_host().

To fix this, goto label 'fail_glue_init', if mmc_add_host() fails,
and change the label 'fail_add_host' to 'fail_gpiod_request'.

605d9fb955 mmc: sdio: fix possible resource leaks in some error paths
If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().

To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().

In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.

Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

2d5cab9232 arm64: dts: qcom: sc8280xp-pmics: Specify interrupt parent explicitly
Nodes like pwrkey, resin, iadc, adc-tm, temp-alarm which are the grand
children of spmi_bus node represent the interrupt generating devices but
don't have "interrupt-parent" property.

As per the devicetree spec v0.3, section 2.4:

"The physical wiring of an interrupt source to an interrupt controller is
represented in the devicetree with the interrupt-parent property. Nodes
that represent interrupt-generating devices contain an interrupt-parent
property which has a phandle value that points to the device to which the
device’s interrupts are routed, typically an interrupt controller. If an
interrupt-generating device does not have an interrupt-parent property,
its interrupt parent is assumed to be its devicetree parent."

This clearly says that if the "interrupt-parent" property is absent, then
the immediate devicetree parent will be assumed as the interrupt parent.
But the immediate parents of these nodes are not interrupt controllers
themselves.

This may lead to failure while wiring the interrupt for these nodes by an
operating system. But a few operating systems like Linux, workaround this
issue by walking up the parent nodes until it finds the "interrupt-cells"
property. Then the node that has the "interrupt-cells" property will be
used as the interrupt parent.

But this workaround is not as per the DT spec and is not being implemented
by other operating systems such as OpenBSD.

Hence, fix this issue by adding the "interrupts-extended" property that
explicitly specifies the spmi_bus node as the interrupt parent. Note that
the "interrupts-extended" property is chosen over "interrupt-parent" as it
allows specifying both interrupt parent phandle and interrupt specifiers in
a single property.

0e4f2c4567 char/agp: consolidate {alloc,free}_gatt_pages()
There is a copy of alloc_gatt_pages() and free_gatt_pages in several
architectures in arch/$ARCH/include/asm/agp.h. All the copies do exactly
the same: alias alloc_gatt_pages() to __get_free_pages(GFP_KERNEL) and
alias free_gatt_pages() to free_pages().

Define alloc_gatt_pages() and free_gatt_pages() in drivers/char/agp/agp.h
and drop per-architecture definitions.
