Subject: ARM: use const and __initconst for smp_operations
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=75305275a721d33ae9abfaeed2817cec8b2fee9a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: use const and __initconst for smp_operations

These smp_operations structures are not over-written, so add "const"
qualifier and replace __initdata with __initconst.

Also, add "static" where it is possible.
