SubjectRe: [PATCH] kbuild: gcov: enable -fno-tree-loop-im if supported
Hi Masahiro and Michal,

The reporter has asked for their email address to be updated to:

psodagud@codeaurora.org

if you're ok with this version of the patch and choose to apply it, can you
please update the commit message. Otherwise, I'll make this change should
we need other changes necessitating a v2.
