From: Jeremy Fitzhardinge Date: Thu, 23 Sep 2010 00:07:27 +0000 (-0700) Subject: tracing/x86: Don't use mcount in pvclock.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9ecd4e1689208afe9b059a5ce1333acb2f42c4d2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git tracing/x86: Don't use mcount in pvclock.c When using a paravirt clock, pvclock.c can be used by sched_clock(), which in turn is used by the tracing mechanism for timestamps, which leads to infinite recursion. Disable mcount/tracing for pvclock.o.
