Subject: ftrace/recordmcount: Modify only executable sections
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8abd5724a7f1631ab2276954156c629d4d17149a;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ftrace/recordmcount: Modify only executable sections

PROGBITS is not enough to determine if the section should be modified
or not. Only process sections that are marked as executable.
