#     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.
#

WARNING: vmlinux.o(.text+0x3484): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init()
The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.

WARNING: vmlinux.o(.text+0x3734): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:early_setup()
The function start_here_multiplatform() references
the function __init early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of early_setup is wrong.

WARNING: vmlinux.o(.text+0x3770): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references

This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
