Donenfeld # Date: Mon Dec 23 14:31:47 2019 +0100 # # powerpc/spinlocks: Include correct header for static key # # 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: 656c21d6af5d ("powerpc/shared: Use static key to detect shared processor") # Signed-off-by: Jason A.
