Subject: [ACPI] reduce kernel size: move 5BK .bss to 2.5KB .init.data
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04348e69e7e78ad69a09b2e1157f628d6c764370;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[ACPI] reduce kernel size: move 5BK .bss to 2.5KB .init.data

put __initdata on sdt_entry[], as it is accessed only by __init functions.
