Subject: [PATCH v2 0/6] powerpc: merge _switch in 32/64
Date: Mon, 15 May 2023 14:45:37 +1000 [thread overview]
Message-ID: <20230515044543.78903-1-npiggin@gmail.com> (raw)
This got a positive response so I'll post again. If anything ppc32 gets
complicated by all the ppc64 crud so if Christophe is okay with it then
it can't be too bad.
Thanks,
Nick
Since v1:
- Don't re-order 32-bit prologue.
- Improve Kconfig conditional includes.
- Break out code changes into their own patches before merging,
so merge patch leaves generated code unchanged.
- Change prom_entry.S to prom_entry_64.S.
