Subject: [PATCH 00/18] powerpc: interrupt wrappers
Date: Fri, 6 Nov 2020 00:34:13 +1000 [thread overview]
Message-ID: <20201105143431.1874789-1-npiggin@gmail.com> (raw)
This is a slightly more polished and tested version. 64e seems to
work okay even with context tracking, and 32s at least boots.
This moves quite a bit more code and C function calls out from asm
to C, it tightens up context tracking significantly on 64s, and
generally moves things closer to the generic entry code.
Thanks,
Nick
Nicholas Piggin (18):
powerpc/64s: move the last of the page fault handling logic to C
powerpc: remove arguments from fault handler functions

powerpc: add interrupt wrapper entry / exit stub functions
powerpc: add interrupt_cond_local_irq_enable helper
powerpc/64: context tracking remove _TIF_NOHZ
powerpc/64: context tracking move to interrupt wrappers
powerpc/64: add context tracking to asynchronous interrupts
powerpc/64s: move context tracking exit to interrupt exit path
powerpc/64s: reconcile interrupts in C
powerpc/64: move account_stolen_time into its own function
powerpc/64: entry cpu time accounting in C
powerpc: move NMI entry/exit code into wrapper
powerpc/64s: move NMI soft-mask handling to C
