Merge tag 'misc-habanalabs-fixes-2020-07-10' of git://people.freedesktop.org/~gabbayo/linux into char-misc-linus

This tag contains the following fixes for 5.8-rc4/5:

- Prevent user from using command WREG_BULK in PCI DMA channel. The command
  won't be parsed correctly by the driver and will cause unknown behavior.
  As the user doesn't need to use that command in that channel, its better
  to just prevent it completely.

- Change the interface of the clock gating debugfs property from true/false
  to bitmask with bit per engine. This will allow the user to debug the
  ASIC while disabling the clock gating feature with fine-grain
  granularity.

- Increase message-to-ASIC-CPU timeout to 4s (from 100ms/1s). The ASIC CPU
  might respond sometimes after a large delay due to slow external
  interfaces (such as temperature sensors) and that will result in a driver
  timeout which will lead to ASIC reset.

The afs filesystem driver allows unstarted operations to be cancelled by
signal, but most of these can easily be restarted (mkdir for example).  The
primary culprits for reproducing this are those applications that use
SIGALRM to display a progress counter.

File lock-extension operation is marked uninterruptible as we have a
limited time in which to do it, and the release op is marked
uninterruptible also as if we fail to unlock a file, we'll have to wait 20
mins before anyone can lock it again.

The store operation logs a warning if it gets interruption, e.g.:

	kAFS: Unexpected error from FS.StoreData -4

because it's run from the background - but it can also be run from
fdatasync()-type things.  However, store options aren't marked
interruptible at the moment.

Fix this in the following ways:

 (1) Mark store operations as uninterruptible.  It might make sense to
     relax this for certain situations, but I'm not sure how to make sure
     that background store ops aren't affected by signals to foreground
     processes that happen to trigger them.

 (2) In afs_get_io_locks(), where we're getting the serialisation lock for
     talking to the fileserver, return ERESTARTSYS rather than EINTR
     because a lot of the operations (e.g. mkdir) are restartable if we
     haven't yet started sending the op to the server.

This reverts commit eb9aecd9

The above patch is supposed to fix a register index error on mt2701. It
is not clear if the problem solved is a hang or just an invalid value
returned, my guess is the second. The patch introduces, though, a new
hang on MT8173 device making them unusable. So, seems reasonable, revert
the patch because introduces a worst issue.

The reason I send a revert instead of trying to fix the issue for MT8173
is because the information needed to fix the issue is in the datasheet
and is not public. So I am not really able to fix it.

Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173
devices.

Naresh Kamboju reported that the LTP tests can cause warnings on i386
going back all the way to v5.0, and bisected it to commit 2c91bd4a


("mm: speed up mremap by 20x on large regions").

The warning in move_normal_pmd() is actually mostly correct, but we have
a very unusual special case at process creation time, when we may move
the stack down with an overlapping mode (kind of like a "memmove()"
except using the page tables).

And when you have just the right condition of "move a large initial
stack by the right alignment in the end, but with the early part of the
move being only page-aligned", we'll be in a situation where we're
trying to move a normal PMD entry on top of an already existing - but
now empty - PMD entry.

The warning is still worth having, in case it ever triggers other cases,
and perhaps as a reminder that we could do the stack move case more
efficiently (although it's clearly rare enough that it probably doesn't
matter).

But make it do WARN_ON_ONCE(), so that you can't flood the logs with it.

And add a *big* comment above it to explain and remind us what's going
on, because it took some figuring out to see how this could trigger.
Kudos to Joel Fernandes for debugging this.

The HSDK pll driver uses the devm_ioremap_resource function, but does
not specify a dependency on IOMEM in Kconfig. This causes a build
failure on architectures without IOMEM, for example, UML (notably with
make allyesconfig).

Fix this by making CONFIG_CLK_HSDK depend on CONFIG_IOMEM.

When building arm32 allmodconfig:

ld.lld: error: undefined symbol: ap_cp_unique_name
>>> referenced by ap-cpu-clk.c
>>>               clk/mvebu/ap-cpu-clk.o:(ap_cpu_clock_probe) in archive drivers/built-in.a

ap_cp_unique_name is only compiled into the kernel image when
CONFIG_ARMADA_AP_CP_HELPER is selected (as it is not user selectable).
However, CONFIG_ARMADA_AP_CPU_CLK does not select it.

This has been a problem since the driver was added to the kernel but it
was not built before commit c318ea261749 ("cpufreq: ap806: fix cpufreq
driver needs ap cpu clk") so it was never noticed.

CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build
(see our Travis link below).

Clang 8 was chosen as a minimum version for this check because there
were some improvements around __builtin_constant_p in that release. In
reality, MIPS was not even buildable until clang 9 so that check was not
technically necessary. Just remove all compiler checks and just assume
that we have a working compiler.

Patch #1 removes inappropriate usage of WARN_ON() following memory

Patch #2 fixes a use-after-free that can be triggered by 'devlink dev
