powerpc/spinlocks: Include correct header for static key
commit6da3eced8c
upstream. Recently, the spinlock implementation grew a static key optimization, but the jump_label.h header include was left out, leading to build errors: linux/arch/powerpc/include/asm/spinlock.h:44:7: error: implicit declaration of function ‘static_branch_unlikely’ 44 | if (!static_branch_unlikely(&shared_processor)) This commit adds the missing header. mpe: The build break is only seen with CONFIG_JUMP_LABEL=n. Fixes:656c21d6af
