The snd_hdac_bus_reset_link() contains logic to clear STATESTS register
before performing controller reset. This code dates back to an old
bugfix in commit e8a7f136 ("[ALSA] hda-intel - Improve HD-audio
codec probing robustness"). Originally the code was added to
azx_reset().

The code was moved around in commit a41d1224 ("ALSA: hda - Embed bus
into controller object") and ended up to snd_hdac_bus_reset_link() and
called primarily via snd_hdac_bus_init_chip().

The logic to clear STATESTS is correct when snd_hdac_bus_init_chip() is
called when controller is not in reset. In this case, STATESTS can be
cleared. This can be useful e.g. when forcing a controller reset to retry
codec probe. A normal non-power-on reset will not clear the bits.

However, this old logic is problematic when controller is already in
reset. The HDA specification states that controller must be taken out of
reset before writing to registers other than GCTL.CRST (1.0a spec,
3.3.7). The write to STATESTS in snd_hdac_bus_reset_link() will be lost
if the controller is already in reset per the HDA specification mentioned.

This has been harmless on older hardware. On newer generation of Intel
PCIe based HDA controllers, if configured to report issues, this write
will emit an unsupported request error. If ACPI Platform Error Interface
(APEI) is enabled in kernel, this will end up to kernel log.

Fix the code in snd_hdac_bus_reset_link() to only clear the STATESTS if
the function is called when controller is not in reset. Otherwise
clearing the bits is not possible and should be skipped.

We need to define the codec pin 0x1b to be the mic, but somehow
the mic doesn't support hot plugging detection, and Windows also has
this issue, so we set it to phantom headset-mic.

Also the determine_headset_type() often returns the omtp type by a
mistake when we plug a ctia headset, this makes the mic can't record
sound at all. Because most of the headset are ctia type nowadays and
some machines have the fixed ctia type audio jack, it is possible this
machine has the fixed ctia jack too. Here we set this mic jack to
fixed ctia type, this could avoid the mic type detection mistake and
make the ctia headset work stable.

For non-4K PAGE_SIZE configs, the largest gigantic huge page size is
CONT_PMD_SHIFT order. On arm64 with 64K PAGE_SIZE, the gigantic page is
16G. Therefore, one should be able to specify 'hugetlb_cma=16G' on the
kernel command line so that one gigantic page can be allocated from CMA.
However, when adding such an option the following message is produced:

hugetlb_cma: cma area should be at least 8796093022208 MiB

This is because the calculation for non-4K gigantic page order is
incorrect in the arm64 specific routine arm64_hugetlb_cma_reserve().

Console drivers often queue work while holding locks also taken in their
console write paths, something which can lead to deadlocks on SMP when
dumping workqueue state (e.g. sysrq-t or on suspend failures).

For serial console drivers this could look like:

	CPU0				CPU1
	----				----

	show_workqueue_state();
	  lock(&pool->lock);		<IRQ>
	  				  lock(&port->lock);
					  schedule_work();
					    lock(&pool->lock);
	  printk();
	    lock(console_owner);
	    lock(&port->lock);

where workqueues are, for example, used to push data to the line
discipline, process break signals and handle modem-status changes. Line
disciplines and serdev drivers can also queue work on write-wakeup
notifications, etc.

Reworking every console driver to avoid queuing work while holding locks
also taken in their write paths would complicate drivers and is neither
desirable or feasible.

Instead use the deferred-printk mechanism to avoid printing while
holding pool locks when dumping workqueue state.

Note that there are a few WARN_ON() assertions in the workqueue code
which could potentially also trigger a deadlock. Hopefully the ongoing
printk rework will provide a general solution for this eventually.

This was originally reported after a lockdep splat when executing
sysrq-t with the imx serial driver.

Michael Forney reported an incorrect padding type that was defined in
the commit 80fe7430 ("ALSA: add new 32-bit layout for
snd_pcm_mmap_status/control") for PCM control mmap data.
His analysis is correct, and this caused the misplacements of PCM
control data on 32bit arch and 32bit compat mode.

The bug is that the __pad2 definition in __snd_pcm_mmap_control64
struct was wrongly with __pad_before_uframe, which should have been
__pad_after_uframe instead.  This struct is used in SYNC_PTR ioctl and
control mmap.  Basically this bug leads to two problems:

- The offset of avail_min field becomes wrong, it's placed right after
  appl_ptr without padding on little-endian

- When appl_ptr and avail_min are read as 64bit values in kernel side,
  the values become either zero or corrupted (mixed up)

One good news is that, because both user-space and kernel
misunderstand the wrong offset, at least, 32bit application running on
32bit kernel works as is.  Also, 64bit applications are unaffected
because the padding size is zero.  The remaining problem is the 32bit
compat mode; as mentioned in the above, avail_min is placed right
after appl_ptr on little-endian archs, 64bit kernel reads bogus values
for appl_ptr updates, which may lead to streaming bugs like jumping,
XRUN or whatever unexpected.
(However, we haven't heard any serious bug reports due to this over
years, so practically seen, it's fairly safe to assume that the impact
by this bug is limited.)

Ideally speaking, we should correct the wrong mmap status control
definition.  But this would cause again incompatibility with the
existing binaries, and fixing it (e.g. by renumbering ioctls) would be
really messy.

So, as of this patch, we only correct the behavior of 32bit compat
mode and keep the rest as is.  Namely, the SYNC_PTR ioctl is now
handled differently in compat mode to read/write the 32bit values at
the right offsets.  The control mmap of 32bit apps on 64bit kernels
has been already disabled (which is likely rather an overlook, but
this worked fine at this time :), so covering SYNC_PTR ioctl should
suffice as a fallback.

The int3472-discrete driver can enter an error path after initialising
int3472->clock.ena_gpio, but before it has registered the clock. This will
cause a NULL pointer dereference, because clkdev_drop() is not null aware.
Instead of guarding the call to skl_int3472_unregister_clock() by checking
for .ena_gpio, check specifically for the presence of the clk_lookup, which
will guarantee clkdev_create() has already been called.

Change kstrtou32() argument 'base' to be zero instead of 'len'.
It works by chance for setting one bit value, but it is not supposed to
work in case value passed to mlxreg_io_attr_store() is greater than 1.

It works for example, for:
echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
But it will fail for:
echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
where n > 1.

The flow for input buffer conversion is as below:
_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
calls:
rv = _parse_integer(s, base, &_res);

For the second case, where n > 1:
- _parse_integer() converts 's' to 'val'.
  For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
  'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
- 'base' is equal or greater then '2' (length of input buffer).

As a result, _parse_integer() exits with result zero (rv):
	rv = 0;
	while (1) {
		...
		if (val >= base)-> (2 >= 2)
			break;
		...
		rv++;
		...
	}

And _kstrtoull() in their turn will fail:
	if (rv == 0)
		return -EINVAL;

Pull objtool fixes from Borislav Petkov:

 - Remove an extra section.len member in favour of section.sh_size

 - Align .altinstructions section creation with the kernel's by creating
   them with entry size of 0

 - Fix objtool to convert a reloc symbol to a section offset and not to
   not warn about not knowing how

Pull x86 fixes from Borislav Petkov:

 - A FPU fix to properly handle invalid MXCSR values: 32-bit masks them
   out due to historical reasons and 64-bit kernels reject them

   config-enabled

 - Three fixes correcting misspelled Kconfig symbols used in code

 - Two resctrl object cleanup fixes

 - Yet another attempt at fixing the neverending saga of botched x86
   timers, this time because some incredibly smart hardware decides to
   turn off the HPET timer in a low power state - who cares if the OS is
   relying on it...

 - Check the full return value range of an SEV VMGEXIT call to determine
   whether it returned an error

Merge tag 'asm-generic-fixes-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic fixes from Arnd Bergmann:
 "There is one build fix for Arm platforms that ended up impacting most
  architectures because of the way the drivers/firmware Kconfig file is
  wired up:

  The CONFIG_QCOM_SCM dependency have caused a number of randconfig
  regressions over time, and some still remain in v5.15-rc4. The fix we
  agreed on in the end is to make this symbol selected by any driver
  using it, and then building it even for non-Arm platforms with
  CONFIG_COMPILE_TEST.

  To make this work on all architectures, the drivers/firmware/Kconfig
  file needs to be included for all architectures to make the symbol
  itself visible.

  In a separate discussion, we found that a sound driver patch that is
  pending for v5.16 needs the same change to include this Kconfig file,
  so the easiest solution seems to have my Kconfig rework included in
  v5.15.

  Finally, the branch also includes a small unrelated build fix for
  NOMMU architectures"
