Hi Linus,

Please pull some more powerpc fixes for 5.9:

The following changes since commit 64ef8f2c4791940d7f3945507b6a45c20d959260:

powerpc/perf/hv-24x7: Move cpumask file to top folder of hv-24x7 driver (2020-08-21 23:35:27 +1000)

are available in the git repository at:

https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-5.9-4

for you to fetch changes up to 4a133eb351ccc275683ad49305d0b04dde903733:

powerpc/32s: Disable VMAP stack which CONFIG_ADB_PMU (2020-08-28 12:03:18 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.9 #4

Revert our removal of PROT_SAO, at least one user expressed an interest in using
it on Power9. Instead don't allow it to be used in guests unless enabled
explicitly at compile time.

A fix for a crash introduced by a recent change to FP handling.

Revert a change to our idle code that left Power10 with no idle support.

One minor fix for the new scv system call path to set PPR.

Fix a crash in our "generic" PMU if branch stack events were enabled.

A fix for the IMC PMU, to correctly identify host kernel samples.

The ADB_PMU powermac code was found to be incompatible with VMAP_STACK, so make
them incompatible in Kconfig until the code can be fixed.

A build fix in drivers/video/fbdev/controlfb.c, and a documentation fix.

Thanks to:
Alexey Kardashevskiy, Athira Rajeev, Christophe Leroy, Giuseppe Sacco,
Madhavan Srinivasan, Milton Miller, Nicholas Piggin, Pratik Rajesh Sampat,
Randy Dunlap, Shawn Anastasio, Vaidyanathan Srinivasan.
