Subject: [PATCH v9 0/8] Disable compat cruft on ppc64le v9
Date: Fri, 13 Sep 2019 14:57:54 +0200 [thread overview]
Message-ID: <cover.1568319275.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/patch/1153850/
https://patchwork.ozlabs.org/patch/1158412/
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
Changes in v6:
- cleanup makefile after split
- consolidate read_user_stack_32
- fix some checkpatch warnings
Changes in v7:
- add back __ARCH_WANT_SYS_LLSEEK to fix build with llseek
- remove leftover hunk
- add review tags
Changes in v8:
- consolidate valid_user_sp to fix it in the split callchain.c
- fix build errors/warnings with PPC64 !COMPAT and PPC32
Changes in v9:
- remove current_is_64bit()
Michal Suchanek (8):
powerpc: Add back __ARCH_WANT_SYS_LLSEEK macro
powerpc: move common register copy functions from signal_32.c to
signal.c
powerpc/perf: consolidate read_user_stack_32
powerpc/perf: consolidate valid_user_sp
powerpc/perf: remove current_is_64bit()
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
