Subject: perf env: Remove unused perf_env__raw_arch
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=da976dd4842981fa9fe8bf736ec3d440fa9ce029;p=thirdparty%2Fkernel%2Flinux.git

perf env: Remove unused perf_env__raw_arch

The switch to using e_machine has made the perf_env__raw_arch function
unused so remove it.
