#     powerpc/syscall: Force inlining of __prep_irq_for_enabled_exit()
#     
#     As reported by kernel test robot, a randconfig with high amount of
#     debuging options can lead to build failure for undefined reference
#     to replay_soft_interrupts() on ppc32.
#     
#     This is due to gcc not seeing that __prep_irq_for_enabled_exit()
#     always returns true on ppc32 because it doesn't inline it for
#     some reason.
#     
#     Force inlining of __prep_irq_for_enabled_exit() to fix the build.
#     
#     Fixes: 344bb20b159d ("powerpc/syscall: Make interrupt.c buildable on PPC32")
