#     powerpc/32: fix build failure on book3e with KVM
#     
#     Build failure was introduced by the commit identified below,
#     due to missed macro expension leading to wrong called function's name.
#     
#     arch/powerpc/kernel/head_fsl_booke.o: In function `SystemCall':
#     arch/powerpc/kernel/head_fsl_booke.S:416: undefined reference to `kvmppc_handler_BOOKE_INTERRUPT_SYSCALL_SPRN_SRR1'
#     Makefile:1052: recipe for target 'vmlinux' failed
#     
#     The called function should be kvmppc_handler_8_0x01B(). This patch fixes it.
#     
#     Reported-by: Paul Mackerras <paulus@ozlabs.org>
