929cbab5b3 habanalabs/gaudi: restore user registers when context opens
Because we don't have multiple contexts in GAUDI, and to minimize
calls to is_idle function (which uses many register reads), move
the call to clear the user registers to the opening of the single
user context.

1fd984f5fe habanalabs/gaudi: minimize number of register reads
Because the register reads might be trapped by the hypervisor in
certain deployments, minimize the number of reads during runtime by
moving static initializations to functions that occur during device
initialization instead of context open.

ASoC: audio-graph: respawn Platform Support
commit 63f2f9cceb ("ASoC: audio-graph: remove Platform support")
removed Platform support from audio-graph, because it doesn't have
"plat" support on DT (simple-card has).
But, Platform support is needed if user is using
snd_dmaengine_pcm_register() which adds generic DMA as Platform.
And this Platform dev is using CPU dev.

Without this patch, at least STM32MP15 audio sound card is no more
functional (v5.13 or later). This patch respawn Platform Support on
audio-graph again.

e38b3f2005 SUNRPC: don't pause on incomplete allocation
alloc_pages_bulk_array() attempts to allocate at least one page based on
the provided pages, and then opportunistically allocates more if that
can be done without dropping the spinlock.

So if it returns fewer than requested, that could just mean that it

Only pause for a time if no progress could be made.

8af52e6977 tools build: Fix feature detect clean for out of source builds
Currently the clean target when using O= isn't cleaning the feature
detect output. This is because O= and OUTPUT= are set to canonical
paths. For example in tools/perf/Makefile:

  FULL_O := $(shell cd $(PWD); readlink -f $(O) || echo $(O))

This means that OUTPUT ends in a / and most usages prepend it to a file
without adding an extra /. This line that was changed adds an extra /
before the 'feature' folder but not to the end, resulting in a clean
command like this:

  rm -f /tmp/build//featuretest-all.bin ...

After the change the clean command looks like this:

  rm -f /tmp/build/feature/test-all.bin ...

e432fe97f3 powerpc/bug: Cast to unsigned long before passing to inline asm
In commit 1e688dd2a3 ("powerpc/bug: Provide better flexibility to
WARN_ON/__WARN_FLAGS() with asm goto") we changed WARN_ON(). Previously
it would take the warning condition, x, and double negate it before
converting the result to int, and passing that int to the underlying
inline asm. ie:

  #define WARN_ON(x) ({
  	int __ret_warn_on = !!(x);
  	if (__builtin_constant_p(__ret_warn_on)) {
  	...
  	} else {
  		BUG_ENTRY(PPC_TLNEI " %4, 0",
  			  BUGFLAG_WARNING | BUGFLAG_TAINT(TAINT_WARN),
  			  "r" (__ret_warn_on));

The asm then does a full register width comparison with zero and traps
if it is non-zero (PPC_TLNEI).

The new code instead passes the full expression, x, with some arbitrary
type, to the inline asm:

  #define WARN_ON(x) ({
	...
	do {
		if (__builtin_constant_p((x))) {
		...
		} else {
			...
			WARN_ENTRY(PPC_TLNEI " %4, 0",
				   BUGFLAG_WARNING | BUGFLAG_TAINT(TAINT_WARN),
				   __label_warn_on, "r" (x));

As reported[1] by Nathan, when building with clang this can cause
spurious warnings to fire repeatedly at boot:

The instruction dump shows that we are trapping because r30 is not zero:
  tdnei   r30,0

Where r30 = c000000007de72c8

The WARN_ON() comes from:

  static void knode_set_klist(struct klist_node *knode, struct klist *klist)
  {
  	knode->n_klist = klist;
  	/* no knode deserves to start its life dead */
  	WARN_ON(knode_dead(knode));
  		      ^^^^^^^^^^^^^^^^^

Where:

  #define KNODE_DEAD		1LU

  static bool knode_dead(struct klist_node *knode)
  {
  	return (unsigned long)knode->n_klist & KNODE_DEAD;
  }

The full disassembly shows that clang has not generated any code to
apply the "& KNODE_DEAD" to the n_klist pointer, which is surprising.

Nathan filed an LLVM bug [2], in which Eli Friedman explained that clang
believes it is only passing a single bit to the asm (ie. a bool) and so
the mask of bit 0 with 1 can be omitted, and suggested that if we want
the full 64-bit value passed to the inline asm we should cast to a
64-bit type (or 32-bit on 32-bits).

In fact we already do that for BUG_ENTRY(), which was added to fix a
possibly similar bug in 2005 in commit 32818c2eb6 ("[PATCH] ppc64: Fix
issue with gcc 4.0 compiled kernels").

So cast the value we pass to the inline asm to long.

For GCC this appears to have no effect on code generation, other than
causing sign extension in some cases.

0e90dfa7a8 net: dsa: tag_rtl4_a: Fix egress tags
I noticed that only port 0 worked on the RTL8366RB since we
started to use custom tags.

It turns out that the format of egress custom tags is actually
different from ingress custom tags. While the lower bits just
contain the port number in ingress tags, egress tags need to
indicate destination port by setting the bit for the
corresponding port.

It was working on port 0 because port 0 added 0x00 as port
number in the lower bits, and if you do this the packet appears
at all ports, including the intended port. Ooops.

Fix this and all ports work again. Use the define for shifting
the "type A" into place while we're at it.

Tested on the D-Link DIR-685 by sending traffic to each of
the ports in turn. It works.

tasks and this API doesn't get CPU cycles for multiple jiffies update.

In addition, increase timeout from usecs_to_jiffies(10000) to
usecs_to_jiffies(20000), to prevent the case that for CONFIG_100HZ
timeout will be a single jiffies.
A single jiffies results actual timeout that can be any time between
1usec and 10msec. To solve this, a value of usecs_to_jiffies(20000)
ensures that timeout is 2 jiffies.

c6132f6f2e bnxt_en: Fix 64-bit doorbell operation on 32-bit kernels
The driver requires 64-bit doorbell writes to be atomic on 32-bit
architectures.  So we redefined writeq as a new macro with spinlock
protection on 32-bit architectures.  This created a new warning when
we added a new file in a recent patchset.  writeq is defined on many
32-bit architectures to do the memory write non-atomically and it
generated a new macro redefined warning.  This warning was fixed
incorrectly in the recent patch.

Fix this properly by adding a new bnxt_writeq() function that will
do the non-atomic write under spinlock on 32-bit systems.  All callers
in the driver will now call bnxt_writeq() instead.

v2: Need to pass in bp to bnxt_writeq()
    Use lo_hi_writeq() [suggested by Florian]

58e636039b xen: remove stray preempt_disable() from PV AP startup code
In cpu_bringup() there is a call of preempt_disable() without a paired
preempt_enable(). This is not needed as interrupts are off initially.
Additionally this will result in early boot messages like:

f956c1b0d5 xen/pcifront: Removed unnecessary __ref annotation
An unnecessary "__ref" annotation was removed from the
"drivers/pci/xen_pcifront.c" file. The function where the annotation
was used was "pcifront_backend_changed()", which does not call any
functions annotated as "__*init" nor "__*exit". This makes "__ref"
unnecessary since this annotation is used to make the compiler ignore
section miss-matches when they are not happening here in the first
place.

In addition to the aforementioned change, some code style issues were
fixed in the same file.

4b92d4add5 drivers: base: cacheinfo: Get rid of DEFINE_SMP_CALL_CACHE_FUNCTION()
DEFINE_SMP_CALL_CACHE_FUNCTION() was usefel before the CPU hotplug rework
to ensure that the cache related functions are called on the upcoming CPU
because the notifier itself could run on any online CPU.

The hotplug state machine guarantees that the callbacks are invoked on the
upcoming CPU. So there is no need to have this SMP function call
obfuscation. That indirection was missed when the hotplug notifiers were
converted.

This also solves the problem of ARM64 init_cache_level() invoking ACPI
functions which take a semaphore in that context. That's invalid as SMP
function calls run with interrupts disabled. Running it just from the
callback in context of the CPU hotplug thread solves this.

b14b8b1ed0 powerpc/ptdump: Fix generic ptdump for 64-bit
Since the conversion to generic ptdump we see crashes on 64-bit:

  BUG: Unable to handle kernel data access on read at 0xc0eeff7f00000000
  Faulting instruction address: 0xc00000000045e5fc
  Oops: Kernel access of bad area, sig: 11 [#1]

    ret_from_kernel_thread+0x5c/0x64

What's happening is that have walked off the end of the kernel page
tables, and started dereferencing junk values.

That happens because we initialised the ptdump_range to span all the way
up to 0xffffffffffffffff:

static struct ptdump_range ptdump_range[] __ro_after_init = {
	{TASK_SIZE_MAX, ~0UL},

But the kernel page tables don't span that far. So on 64-bit set the end
of the range to be the address immediately past the end of the kernel
page tables, to limit the page table walk to valid addresses.

85dfdbfc13 mailbox: cmdq: add multi-gce clocks support for mt8195
For the design of GCE hardware event signal transportation,
evnet rx will send the event signal to all GCE event merges
after receiving the event signal from the other hardware.

Because GCE event merges need to response to event rx, their
clocks must be enabled at that time.

To make sure all the gce clock is enabled while receiving the
hardware event, each cmdq mailbox should enable or disable
the others gce clk at the same time.

Merge tag 'for-5.15/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

 - Add DM infrastructure for IMA-based remote attestion. These changes
   are the basis for deploying DM-based storage in a "cloud" that must
   validate configurations end-users run to maintain trust. These DM
   changes allow supported DM targets' configurations to be measured via
   IMA. But the policy and enforcement (of which configurations are
   valid) is managed by something outside the kernel (e.g. Keylime).

 - Fix DM crypt scalability regression on systems with many cpus due to
   percpu_counter spinlock contention in crypt_page_alloc().

 - Use in_hardirq() instead of deprecated in_irq() in DM crypt.

 - Add event counters to DM writecache to allow users to further assess
   how the writecache is performing.

 - Various code cleanup in DM writecache's main IO mapping function.

9605f75cf3 f2fs: should put a page beyond EOF when preparing a write
The prepare_compress_overwrite() gets/locks a page to prepare a read, and calls
f2fs_read_multi_pages() which checks EOF first. If there's any page beyond EOF,
we unlock the page and set cc->rpages[i] = NULL, which we can't put the page
anymore. This makes page leak, so let's fix by putting that page.

827f02842e f2fs: deallocate compressed pages when error happens
In f2fs_write_multi_pages(), f2fs_compress_pages() allocates pages for
compression work in cc->cpages[]. Then, f2fs_write_compressed_pages() initiates
bio submission. But, if there's any error before submitting the IOs like early
f2fs_cp_error(), previously it didn't free cpages by f2fs_compress_free_page().
Let's fix memory leak by putting that just before deallocating cc->cpages.
