Subject: [RFC PATCH 0/4] objtool: Enable and implement --mcount option on powerpc
Date: Mon, 23 May 2022 23:25:44 +0530	[thread overview]
Message-ID: <20220523175548.922671-1-sv@linux.ibm.com> (raw)

These patches are rebased on top of objtool/core
branch of the tip tree, and work only on ppc64le
for now. 

Note: With this patch set, there are still some 
warnings seen with ppc64le kernel build.

Sathvika Vasireddy (4):
  objtool: Add --mnop as an option to --mcount
  objtool: Enable objtool to run only on files with ftrace enabled
  objtool/powerpc: Enable objtool to be built on ppc
  objtool/powerpc: Add --mcount specific implementation
