This takes patch 6/8 and 7/8 of v8 as the base. > Removes the extra strict check in gcc-profile-kernel-notrace.sh > and adds logic for checking offsets in livepatch. The patch > for HAVE_C_RECORDMCOUNT is not required and not used here. > > Depending on whether or not a TOC is generated, the offset > for _mcount can be +16,+12,+8,+4. The changes are such that the > offset checks are specific to powerpc. > > TODOs > 1. Build a version with offsets removed and rebuild > ftrace_location() sort of functionality > 2. Make livepatching experimental on powerpc > > Comments? Testing? I tested the sample in the livepatch > directory > > References > > 1. https://patchwork.ozlabs.org/patch/581521/ > 2. https://patchwork.ozlabs.org/patch/587464/ > > Signed-off-by: Torsten Duwe <duwe@xxxxxxx> > Signed-off-by: Balbir Singh <bsingharora@xxxxxxxxx> Tested-by: Kamalesh Babulal <kamalesh@xxxxxxxxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe live-patching" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
