Linus Torvalds 8bb5021cc2 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,
