Subject: [PATCH v2 00/13] Implement livepatch on PPC32 and more
Date: Mon, 20 Dec 2021 16:37:58 +0000 [thread overview]
Message-ID: <cover.1640017960.git.christophe.leroy@csgroup.eu> (raw)
This series implements livepatch on PPC32 and implements
CONFIG_DYNAMIC_FTRACE_WITH_ARGS to simplify ftracing.
v2:
- Fix problem with strict modules RWX
- Convert powerpc to CONFIG_DYNAMIC_FTRACE_WITH_ARGS
- Convert function graph tracing to C
- Refactor PPC32 versus PPC64
Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu>
Christophe Leroy (13):
livepatch: Fix build failure on 32 bits processors
tracing: Fix selftest config check for function graph start up test
powerpc/module_32: Fix livepatching for RO modules
powerpc/ftrace: Add support for livepatch to PPC32

powerpc/ftrace: Simplify PPC32's return_to_handler()
powerpc/ftrace: Prepare PPC32's ftrace_caller() for
CONFIG_DYNAMIC_FTRACE_WITH_ARGS
powerpc/ftrace: Prepare PPC64's ftrace_caller() for
CONFIG_DYNAMIC_FTRACE_WITH_ARGS
powerpc/ftrace: Implement CONFIG_DYNAMIC_FTRACE_WITH_ARGS
powerpc/ftrace: Refactor ftrace_{en/dis}able_ftrace_graph_caller
powerpc/ftrace: directly call of function graph tracer by ftrace
caller
powerpc/ftrace: Prepare ftrace_64_mprofile.S for reuse by PPC32
powerpc/ftrace: Remove ftrace_32.S
