Subject: ftrace: Add .kprobe.text section to whitelist for recordmcount.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9f087e7612115b7a201d4f3392a95ac7408948ab;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ftrace: Add .kprobe.text section to whitelist for recordmcount.c

The .kprobe.text section is safe to modify mcount to nop and tracing.
Add it to the whitelist in recordmcount.c and recordmcount.pl.
