Subject: x86/asm/boot: Use already defined KEEP_SEGMENTS macro in head_{32,64}.S
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb148d83ec6924b7766731e58739d7281b6fb8c7;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

x86/asm/boot: Use already defined KEEP_SEGMENTS macro in head_{32,64}.S

There is already defined macro KEEP_SEGMENTS in
<asm/bootparam.h>, let's use it instead of hardcoded
constants.
