Subject: [PATCH v8 0/8] powerpc: switch VDSO to C implementation
Date: Tue, 28 Apr 2020 13:16:46 +0000 (UTC)	[thread overview]
Message-ID: <cover.1588079622.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 v7 are:
- Added gettime64 on PPC32

This series applies on today's powerpc/merge branch.

See the last patches for details on changes and performance.

Christophe Leroy (8):
  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.
  lib/vdso: force inlining of __cvdso_clock_gettime_common()
  powerpc/vdso: Provide __kernel_clock_gettime64() on vdso32
