Subject: [PATCH v5 0/5] Disable compat cruft on ppc64le v5
Date: Fri, 30 Aug 2019 00:28:35 +0200 [thread overview]
Message-ID: <cover.1567117050.git.msuchanek@suse.de> (raw)
Less code means less bugs so add a knob to skip the compat stuff.
This is tested on ppc64le top of
https://patchwork.ozlabs.org/cover/1153556/
Changes in v2: saner CONFIG_COMPAT ifdefs
Changes in v3:
- change llseek to 32bit instead of builing it unconditionally in fs
- clanup the makefile conditionals
- remove some ifdefs or convert to IS_DEFINED where possible
Changes in v4:
- cleanup is_32bit_task and current_is_64bit
- more makefile cleanup
Changes in v5:
- more current_is_64bit cleanup
- split off callchain.c 32bit and 64bit parts
Michal Suchanek (5):
powerpc: make llseek 32bit-only.
powerpc: move common register copy functions from signal_32.c to
signal.c
powerpc/64: make buildable without CONFIG_COMPAT
powerpc/64: Make COMPAT user-selectable disabled on littleendian by
default.
powerpc/perf: split callchain.c by bitness
