Subject: [POWERPC] Fix COMMON symbol warnings
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=991eb43af989002d5c7f4a2ff2a6c806a912b51b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[POWERPC] Fix COMMON symbol warnings

We get the following warnings in various ARCH=powerpc builds:

WARNING: "ee_restarts" [arch/powerpc/kernel/built-in] is COMMON symbol
WARNING: "fee_restarts" [arch/powerpc/kernel/built-in] is COMMON symbol
WARNING: "htab_hash_searches" [arch/powerpc/mm/built-in] is COMMON symbol
WARNING: "next_slot" [arch/powerpc/mm/built-in] is COMMON symbol
WARNING: "mmu_hash_lock" [arch/powerpc/mm/built-in] is COMMON symbol
WARNING: "primary_pteg_full" [arch/powerpc/mm/built-in] is COMMON symbol
WARNING: "global_dbcr0" [arch/powerpc/kernel/built-in] is COMMON symbol

Switch to moving local symbols (except mmu_hash_lock which is global) and
space directive instead.
