This reverts commit a3b884ce ("firmware: arm_scmi: Add clock management
to the SCMI power domain").

Using the GENPD_FLAG_PM_CLK tells genpd to gate/ungate the consumer
device's clock(s) during runtime suspend/resume through the PM clock API.
More precisely, in genpd_runtime_resume() the clock(s) for the consumer
device would become ungated prior to the driver-level ->runtime_resume()
callbacks gets invoked.

This behaviour isn't a good fit for all platforms/drivers. For example, a
driver may need to make some preparations of its device in its
->runtime_resume() callback, like calling clk_set_rate() before the
clock(s) should be ungated. In these cases, it's easier to let the clock(s)
to be managed solely by the driver, rather than at the PM domain level.

For these reasons, let's drop the use GENPD_FLAG_PM_CLK for the SCMI PM
domain, as to enable it to be more easily adopted across ARM platforms.

This loop intends to retry a max of 10 times, with some implicit
termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the
termination condition depends on the value reported by the SD card
(*rocr), which may or may not correctly reflect what we asked it to do.

Needless to say, it's not wise to rely on the card doing what we expect;
we should at least terminate the loop regardless. So, check both the
input and output values, so we ensure we will terminate regardless of
the SD card behavior.

Note that SDIO learned a similar retry loop in commit 0797e5f1
("mmc: core: Fixup signal voltage switch"), but that used the 'ocr'
result, and so the current pre-terminating condition looks like:

    rocr & ocr & R4_18V_PRESENT

(i.e., it doesn't have the same bug.)

This addresses a number of crash reports seen on ChromeOS that look
like the following:

According to the datasheet [1] at page 377, 4-bit bus width is turned on by
bit 2 of the Bus Width Register. Thus the current bitmask is wrong: define
BUS_WIDTH_4 BIT(1)

BIT(1) does not work but BIT(2) works. This has been verified on real MOXA
hardware with FTSDC010 controller revision 1_6_0.

The corrected value of BUS_WIDTH_4 mask collides with: define BUS_WIDTH_8
BIT(2). Additionally, 8-bit bus width mode isn't supported according to the
datasheet, so let's remove the corresponding code.

The AMD IOMMU driver cannot activate PASID mode on a RID without the RID's
translation being set to IDENTITY. Further it requires changing the RID's
page table layout from the normal v1 IOMMU_DOMAIN_IDENTITY layout to a
different v2 layout.

It does this by creating a new iommu_domain, configuring that domain for
v2 identity operation and then attaching it to the group, from within the
driver. This logic assumes the group is already set to the IDENTITY domain
and is being used by the DMA API.

However, since the ownership logic is based on the group's domain pointer
equaling the default domain to detect DMA API ownership, this causes it to
look like the group is not attached to the DMA API any more. This blocks
attaching drivers to any other devices in the group.

In a real system this manifests itself as the HD-audio devices on some AMD
platforms losing their device drivers.

Work around this unique behavior of the AMD driver by checking for
equality of IDENTITY domains based on their type, not their pointer
value. This allows the AMD driver to have two IDENTITY domains for
internal purposes without breaking the check.

Have the AMD driver properly declare that the special domain it created is
actually an IDENTITY domain.

The global rwsem dmar_global_lock was introduced by commit 3a5670e8
("iommu/vt-d: Introduce a rwsem to protect global data structures"). It
is used to protect DMAR related global data from DMAR hotplug operations.

The dmar_global_lock used in the intel_iommu_init() might cause recursive
locking issue, for example, intel_iommu_get_resv_regions() is taking the
dmar_global_lock from within a section where intel_iommu_init() already
holds it via probe_acpi_namespace_devices().

Using dmar_global_lock in intel_iommu_init() could be relaxed since it is
unlikely that any IO board must be hot added before the IOMMU subsystem is
initialized. This eliminates the possible recursive locking issue by moving
down DMAR hotplug support after the IOMMU is initialized and removing the
uses of dmar_global_lock in intel_iommu_init().

Commit c4617318 ("MIPS: Add NUMA support for Loongson-3") has increased
.bss size of the Octeon kernel from 16k to 16M. Providing the conditions
for SPARSEMEM_EXTREME avoids the waste of memory.

Thomas has tested the loogsoon64 kernel, where .bss is being reduced by
this patch from 16.5M to 515k.

We have a couple of problems, first reports of unexpected link breakage
for reads when cqe->res indicates that the IO was done in full. The
reason here is partial IO with retries.

TL;DR; we compare the result in __io_complete_rw_common() against
req->cqe.res, but req->cqe.res doesn't store the full length but rather
the length left to be done. So, when we pass the full corrected result
via kiocb_done() -> __io_complete_rw_common(), it fails.

The second problem is that we don't try to correct res in
io_complete_rw(), which, for instance, might be a problem for O_DIRECT
but when a prefix of data was cached in the page cache. We also
definitely don't want to pass a corrected result into io_rw_done().

The fix here is to leave __io_complete_rw_common() alone, always pass
not corrected result into it and fix it up as the last step just before
actually finishing the I/O.

Users may have explicitly configured their tracefs permissions; we
shouldn't overwrite those just because a second mount appeared.

Only clobber if the options were provided at mount time.

Note: the previous behavior was especially surprising in the presence of
automounted /sys/kernel/debug/tracing/.

Existing behavior:

  ## Pre-existing status: tracefs is 0755.
  # stat -c '%A' /sys/kernel/tracing/
  drwxr-xr-x

  ## (Re)trigger the automount.
  # umount /sys/kernel/debug/tracing
  # stat -c '%A' /sys/kernel/debug/tracing/.
  drwx------

  ## Unexpected: the automount changed mode for other mount instances.
  # stat -c '%A' /sys/kernel/tracing/
  drwx------

New behavior (after this change):

  ## Pre-existing status: tracefs is 0755.
  # stat -c '%A' /sys/kernel/tracing/
  drwxr-xr-x

  ## (Re)trigger the automount.
  # umount /sys/kernel/debug/tracing
  # stat -c '%A' /sys/kernel/debug/tracing/.

  ## Expected: the automount does not change other mount instances.
  # stat -c '%A' /sys/kernel/tracing/

The system call gate area counts as kernel text but trying
to install a kprobe in this area fails with an Oops later on.
To fix this explicitly disallow the gate area for kprobes.
