I should have avoided CONFIG_ARM64 in the the header file which gets
duplicated for tools/include/.. Looking at this once again, platform
build wrappers are not really required for these arch overrides. These
arm64 branch types can co-exist with any other platform overrides when
they get added later on. Just that the branch type nomenclature should
include the platform name some where. Something like ..
PERF_BR_<ARCH>_<BRANCH_TYPE>
#define PERF_BR_ARM64_FIQ PERF_BR_NEW_ARCH_1
#define PERF_BR_ARM64_DEBUG_HALT PERF_BR_NEW_ARCH_2
#define PERF_BR_ARM64_DEBUG_EXIT PERF_BR_NEW_ARCH_3
#define PERF_BR_ARM64_DEBUG_INST PERF_BR_NEW_ARCH_4
#define PERF_BR_ARM64_DEBUG_DATA PERF_BR_NEW_ARCH_5
Will do this change next time around.
