Subject: [PATCH v7 0/7] powerpc: switch VDSO to C implementation
Date: Mon, 20 Apr 2020 16:56:27 +0000 (UTC) [thread overview]
Message-ID: <cover.1587401492.git.christophe.leroy@c-s.fr> (raw)
This is the seventh version of a series to switch powerpc VDSO to
generic C implementation.
Main changes since v6 are:
- Added -fasynchronous-unwind-tables in CFLAGS
- Split patch 2 in two parts
- Split patch 5 (which was patch 4) in two parts
This series applies on today's powerpc/merge branch.
See the last two patches for details on changes and performance.
Christophe Leroy (7):
powerpc/vdso64: Switch from __get_datapage() to get_datapage inline
macro
powerpc/vdso: Remove __kernel_datapage_offset and simplify
__get_datapage()
powerpc/vdso: Remove unused \tmp param in __get_datapage()
powerpc/processor: Move cpu_relax() into asm/vdso/processor.h
powerpc/vdso: Prepare for switching VDSO to generic C implementation.
powerpc/vdso: Switch VDSO to generic C implementation.
