From: Baoquan He Date: Sun, 9 Jul 2017 12:37:41 +0000 (+0800) Subject: x86/boot/KASLR: Rename process_e820_entry() into process_mem_region() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=27aac20574110abfd594175a668dc58b23b2b14a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git x86/boot/KASLR: Rename process_e820_entry() into process_mem_region() Now process_e820_entry() is not limited to e820 entry processing, rename it to process_mem_region(). And adjust the code comment accordingly.
