This can result in a subsequent unrelated process getting an spurious

This polls the PSL to ensure that the PSL is clear of IRQs for the

Keep IRQ mappings on context teardown. This won't leak IRQs as if we
allocate the mapping again, the generic code will give the same
mapping used last time.
Doing this works around a race in the generic code. Masking the
interrupt introduces a race which can crash the kernel or result in
IRQ that is never EOIed. The lost of EOI results in all subsequent
mappings to the same HW IRQ never receiving an interrupt.
We've seen this race with cxl test cases which are doing heavy context
startup and teardown at the same time as heavy interrupt load.
A fix to the generic code is being investigated also.

With just one preallocated workspace we can guarantee forward progress
even if there's no memory available for new workspaces. The cost is more
waiting but we also get rid of several error paths.
On average, there will be several idle workspaces, so the waiting
penalty won't be so bad.
In the worst case, all cpus will compete for one workspace until there's
some memory. Attempts to allocate a new one are done each time the
waiters are woken up.

Preallocate one workspace for each compression type so we can guarantee
forward progress in the worst case. A failure cannot be a hard error as
we might not use compression at all on the filesystem. If we can't
allocate the workspaces later when need them, it might actually
deadlock, but in such situation the system has effectively not enough
memory to operate properly.

Need to move the free function around a bit, but otherwise mostly
just removing code.
Specifically we can nuke all the _locked variants since the weak idr
reference is now protected by the idr_mutex, which we never hold
anywhere expect in the lookup/reg/unreg functions. And those never
call anything else.
Another benefit of this is that this patch switches the weak reference
logic from kref_put_mutex to kref_get_unless_zero. And the later is in
general more flexible wrt accomodating multiple weak references
protected by different locks, which might or might not come handy
eventually.
But one consequence of that switch is that we need to acquire the
blob_lock from the free function for the list_del calls. That's a bit
tricky to pull off, but works well if we pick the exact same scheme as
is already used for framebuffers. Most important changes:
- filp list is maintainer by create/destroy_blob ioctls directly
(already the case, so we can just remove the redundant list_del from
the free function).
- filp close handler walks the filp-private list lockless - works
because we know no one else can access it. I copied the same comment
from the fb code over to explain this.
- Otherwise we need to sufficiently restrict blob_lock critical
sections to avoid all the unreference calls. Easy to do once the
blob_lock only protects the list, and no longer the weak reference.

In the ppc64 big endian ABI, function symbols point to function
descriptors. The symbols which point to the function entry points
have a dot in front of the function name. Consequently, when the
ftrace filter mechanism searches for the symbol corresponding to
an entry point address, it gets the dot symbol.
As a result, ftrace filter users have to be aware of this ABI detail on
ppc64 and prepend a dot to the function name when setting the filter.
The perf probe command insulates the user from this by ignoring the dot
in front of the symbol name when matching function names to symbols,
but the sysfs interface does not. This patch makes the ftrace filter
mechanism do the same when searching symbols.
Fixes the following failure in ftracetest's kprobe_ftrace.tc:
.../kprobe_ftrace.tc: line 9: echo: write error: Invalid argument
That failure is on this line of kprobe_ftrace.tc:
echo _do_fork > set_ftrace_filter
This is because there's no _do_fork entry in the functions list:
# cat available_filter_functions | grep _do_fork
._do_fork
This change introduces no regressions on the perf and ftracetest
testsuite results.

The copy paste facility introduced in POWER9 provides an optimised
mechanism for a userspace application to copy a cacheline. This is
provided by a pair of instructions, copy and paste, while a third,
cp_abort (copy paste abort), provides a clean up of the state in case of
a failure.
The copy instruction will read a 128 byte cacheline and store it in an
internal buffer. The subsequent paste instruction will store this
internal buffer to memory and set a CR field if the paste succeeds.
Since the state of the copy paste buffer is internal (and not
architecturally visible), in the unlikely event of a context switch, the
state cannot be stored and the paste should therefore fail.
The cp_abort instruction exists to fail and clean up any such
interrupted copy paste sequence and is to be called by the kernel as
part of the context switch. Doing so prevents data from a preceding copy
in one process leaking into the paste of another.
This code enables use of the cp_abort instruction if a supported
processor is detected.
NOTE: this is for userspace only, not in kernel, and does not deal
with KVM guests.

mpic_init_sys() currently doesn't check whether
subsys_system_register() succeeded or not. Check the return code of
subsys_system_register() and clean up if there's an error.

just a single fix to not move the GPU linear window on cores where it
might lead to inconsistent views of the memory by different engines in
the core, thus breaking relocs and possibly causing other fun.
* 'drm-etnaviv-fixes' of git://git.pengutronix.de:/git/lst/linux:
drm/etnaviv: don't move linear memory window on 3D cores without MC2.0
recent regressions. Changes are across several platforms, so
I'm listing every change separately here.
Regressions since 4.5:
- A correction of the psci firmware DT binding, to prevent
users from relying on unintended semantics
- Actually getting the newly merged clock driver for some OMAP
platforms to work
- A revert of patches for the Qualcomm BAM, these need to be
reworked for 4.7 to avoid breaking boards other than the one
they were intended for
- A correction for the I2C device nodes on the Socionext Uniphier
platform
- i.MX SDHCI was broken for non-DT platforms due to a change
with the setting of the DMA mask
- A revert of a patch that accidentally added a nonexisting
clock on the Rensas "Porter" board
- A couple of OMAP fixes that are all related to suspend after
the power domain changes for dra7
- On Mediatek, revert part of the power domain initialization
changes that broke mt8173-evb
Fixes for older bugs:
- Workaround for an "external abort" in the omap34xx
suspend/resume code.
- The USB1/eSATA should not be listed as an excon device on
am57xx-beagle-x15 (broken since v4.0)
- A v4.5 regression in the TI AM33xx and AM43XX DT specifying
incorrect DMA request lines for the GPMC
- The jiffies calibration on Renesas platforms was incorrect
for some modern CPU cores.
- A hardware errata woraround for clockdomains on TI DRA7
