Subject: x86: add ENDPROC() markers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6b8be6df7f971919622d152d144c8798ad7fd160;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

x86: add ENDPROC() markers

The ENDPROCs() were not used everywhere.  Some code used just END() instead,
while other code used nothing.  um/sys-i386/checksum.S didn't #include
<linux/linkage.h> .  I also got confused because gcc puts the
.type near the ENTRY, while ENDPROC puts it on the opposite end.
