If the EC GPE status is not set after checking all of the other GPEs,
acpi_s2idle_wake() returns 'false', to indicate that the SCI event
that has just triggered is not a system wakeup one, but it does that
without canceling the pending wakeup and re-arming the SCI for system
wakeup which is a mistake, because it may cause s2idle_loop() to busy
spin until the next valid wakeup event. [If that happens, the first
spurious wakeup is still pending after acpi_s2idle_wake() has
returned, so s2idle_enter() does nothing, acpi_s2idle_wake()
is called again and it sees that the SCI has triggered, but no GPEs
are active, so 'false' is returned again, and so on.]
Fix that by moving all of the GPE checking logic from
acpi_s2idle_wake() to acpi_ec_dispatch_gpe() and making the
latter return 'true' only if a non-EC GPE has triggered and
'false' otherwise, which will cause acpi_s2idle_wake() to
cancel the pending SCI wakeup and re-arm the SCI for system
wakeup regardless of the EC GPE status.
This also addresses a lockup observed on an Elitegroup EF20EA laptop
after attempting to wake it up from suspend-to-idle by a key press.

if some function in ndo_stop interface returns failure because of
hardware fault, must go on excuting rest steps rather than return
failure directly, otherwise will cause memory leak.And bump the
timeout for SET_FUNC_STATE to ensure that cmd won't return failure
when hw is busy. Otherwise hw may stomp host memory if we free
memory regardless of the return value of SET_FUNC_STATE.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu fixes from Joerg Roedel:
- Race condition fixes for the AMD IOMMU driver.
These are five patches fixing two race conditions around
increase_address_space(). The first race condition was around the
non-atomic update of the domain page-table root pointer and the
variable containing the page-table depth (called mode). This is fixed
now be merging page-table root and mode into one 64-bit field which
is read/written atomically.
The second race condition was around updating the page-table root
pointer and making it public before the hardware caches were flushed.
This could cause addresses to be mapped and returned to drivers which
are not reachable by IOMMU hardware yet, causing IO page-faults. This
is fixed too by adding the necessary flushes before a new page-table
root is published.
Related to the race condition fixes these patches also add a missing
domain_flush_complete() barrier to update_domain() and a fix to bail
out of the loop which tries to increase the address space when the
call to increase_address_space() fails.
Qian was able to trigger the race conditions under high load and
memory pressure within a few days of testing. He confirmed that he
has seen no issues anymore with the fixes included here.
- Fix for a list-handling bug in the VirtIO IOMMU driver.

It seems that for whatever reason, gcc-10 ends up not inlining a couple
of functions that used to be inlined before. Even if they only have one
single callsite - it looks like gcc may have decided that the code was
unlikely, and not worth inlining.
The code generation difference is harmless, but caused a few new section
mismatch errors, since the (now no longer inlined) function wasn't in
the __init section, but called other init functions:
Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem()
Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memremap()
Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap()
So add the appropriate __init annotation to make modpost not complain.
In both cases there were trivially just a single callsite from another
__init function.

I ran into a randconfig build failure with CONFIG_FIXED_PHY=m
and CONFIG_GIANFAR=y:
x86_64-linux-ld: drivers/net/ethernet/freescale/gianfar.o:(.rodata+0x418): undefined reference to `fixed_phy_change_carrier'
It seems the same thing can happen with dpaa and ucc_geth, so change
all three to do an explicit 'select FIXED_PHY'.
The fixed-phy driver actually has an alternative stub function that
theoretically allows building network drivers when fixed-phy is
disabled, but I don't see how that would help here, as the drivers
presumably would not work then.

When the controller is reconnecting, the host fails I/O and admin
commands as the host cannot reach the controller. ns scanning may
revalidate namespaces during that period and it is wrong to remove
namespaces due to these failures as we may hang (see 205da2434301).
One command that may fail is nvme_identify_ns_descs. Since we return
success due to having ns identify descriptor list optional, we continue
to compare ns identifiers in nvme_revalidate_disk, obviously fail and
return -ENODEV to nvme_validate_ns, which will remove the namespace.
Exactly what we don't want to happen.

The check for the HWO flag in dwc3_gadget_ep_reclaim_trb_sg()
causes us to break out of the loop before we call
dwc3_gadget_ep_reclaim_completed_trb(), which is what likely
should be clearing the HWO flag.
This can cause odd behavior where we never reclaim all the trbs
in the sg list, so we never call giveback on a usb req, and that
will causes transfer stalls.
This effectively resovles the adb stalls seen on HiKey960
after userland changes started only using AIO in adbd.

[Why]
We're sending the drm vblank event a frame too early in the case where
the pageflip happens close to VUPDATE and ends up blocking the signal.
The implementation in DM was previously correct *before* we started
sending vblank events from VSTARTUP unconditionally to handle cases
where HUBP was off, OTG was ON and userspace was still requesting some
DRM planes enabled. As part of that patch series we dropped VUPDATE
since it was deemed close enough to VSTARTUP, but there's a key
difference betweeen VSTARTUP and VUPDATE - the VUPDATE signal can be
blocked if we're holding the pipe lock.
There was a fix recently to revert the unconditional behavior for the
DCN VSTARTUP vblank event since it was sending the pageflip event on
the wrong frame - once again, due to blocking VUPDATE and having the
address start scanning out two frames later.
The problem with this fix is it didn't update the logic that calls
drm_crtc_handle_vblank(), so the timestamps are totally bogus now.
[How]
Essentially reverts most of the original VSTARTUP series but retains
the behavior to send back events when active planes == 0.
Some refactoring/cleanup was done to not have duplicated code in both
the handlers.
Fixes: 16f17eda8bad ("drm/amd/display: Send vblank and user events at vsartup for DCN")
Fixes: 3a2ce8d66a4b ("drm/amd/display: Disable VUpdate interrupt for DCN hardware")

Releasing the AMDGPU BO ref directly leads to problems when BOs were
exported as DMA bufs. Releasing the GEM reference makes sure that the
AMDGPU/TTM BO is not freed too early.
Also take a GEM reference when importing BOs from DMABufs to keep
references to imported BOs balances properly.

First, it should be noted that the CQE timeout (60 seconds) is substantial
so a CQE request that times out is really stuck, and the race between
timeout and completion is extremely unlikely. Nevertheless this patch
fixes an issue with it.
Commit ad73d6feadbd7b ("mmc: complete requests from ->timeout")
preserved the existing functionality, to complete the request.
However that had only been necessary because the block layer
timeout handler had been marking the request to prevent it from being
completed normally. That restriction was removed at the same time, the
result being that a request that has gone will have been completed anyway.
That is, the completion was unnecessary.
At the time, the unnecessary completion was harmless because the block
layer would ignore it, although that changed in kernel v5.0.
Note for stable, this patch will not apply cleanly without patch "mmc:
core: Fix recursive locking issue in CQE recovery path"

Consider the following stack trace
-001|raw_spin_lock_irqsave
-002|mmc_blk_cqe_complete_rq
-003|__blk_mq_complete_request(inline)
-003|blk_mq_complete_request(rq)
-004|mmc_cqe_timed_out(inline)
-004|mmc_mq_timed_out
mmc_mq_timed_out acquires the queue_lock for the first
time. The mmc_blk_cqe_complete_rq function also tries to acquire
the same queue lock resulting in recursive locking where the task
is spinning for the same lock which it has already acquired leading
to watchdog bark.
Fix this issue with the lock only for the required critical section.

In the request completion path with CQE, request type is being checked
after the request is getting completed. This is resulting in returning
the wrong request type and leading to the IO hang issue.
ASYNC request type is getting returned for DCMD type requests.
Because of this mismatch, mq->cqe_busy flag is never getting cleared
and the driver is not invoking blk_mq_hw_run_queue. So requests are not
getting dispatched to the LLD from the block layer.
All these eventually leading to IO hang issues.
So, get the request type before completing the request.
