[PATCH 4.7 003/141] scripts/recordmcount.c: account for .softirqentry.text

From: Greg Kroah-Hartman
Date: Thu Oct 06 2016 - 04:32:43 EST


4.7-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dmitry Vyukov <dvyukov@xxxxxxxxxx>

commit e436fd61a8f62cb7a16310a42b95ab076ff72eff upstream.

be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into
separate sections") added .softirqentry.text section, but it was not added
to recordmcount. So functions in the section are untracable. Add the
section to scripts/recordmcount.c and scripts/recordmcount.pl.

Fixes: be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections")
