Subject: [PATCH v2 00/19] powerpc: interrupt wrappers
Date: Wed, 11 Nov 2020 19:43:51 +1000	[thread overview]
Message-ID: <20201111094410.3038123-1-npiggin@gmail.com> (raw)

This adds interrupt handler wrapper functions, similar to the
generic / x86 code, and moves several common operations into them
from either asm or open coded in the individual handlers.

Since v1:
- Fixed a couple of compile issues
- Fixed perf weirdness (sometimes NMI, sometimes not)
- Also move irq_enter/exit into wrappers

Thanks,
Nick
