Subject: perf c2c: Use perf_env e_machine rather than arch
X-Git-Url: http://git.ipfire.org/index.cgi?a=commitdiff_plain;h=70b3c4f734bbfd5664cd6e4eb007c108bf2b1c43;p=thirdparty%2Fkernel%2Flinux.git

perf c2c: Use perf_env e_machine rather than arch

Use the e_machine rather than arch string matching for AARCH64.

Add include of dwarf-regs.h in case the EM_AARCH64 isn't defined, sort
the headers given this include.
