  powerpc/64e/interrupt: Fix nvgprs being clobbered (2021-05-14 17:28:54 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.13 #3

 - Fix a regression in the conversion of the 64-bit BookE interrupt entry to C.

 - Fix KVM hosts running with the hash MMU since the recent KVM gfn changes.

 - Fix a deadlock in our paravirt spinlocks when hcall tracing is enabled.

 - Several fixes for oopses in our runtime code patching for security mitigations.

 - A couple of minor fixes for the recent conversion of 32-bit interrupt entry/exit to C.

 - Fix __get_user() causing spurious crashes in sigreturn due to a bad inline asm
   constraint, spotted with GCC 11.

 - A fix for the way we track IRQ masking state vs NMI interrupts when using the new scv
   system call entry path.

 - A couple more minor fixes.

Thanks to: Cédric Le Goater, Christian Zigotzky, Christophe Leroy, Naveen N. Rao, Nicholas
Piggin Paul Menzel, Sean Christopherson.
