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’ [-Werror=implicit-function-declaration]
44 | if (!static_branch_unlikely(&shared_processor))
This commit adds the missing header.
Fixes: 656c21d6af5d ("powerpc/shared: Use static key to detect shared
processor")
