[PATCH] i386: make apic probe function non-init
o struct genapic contains pointer to probe() function which is of type
__init. Hence MODPOST generates warning if kernel is compiled with
CONFIG_RELOCATABLE=y for i386.
WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_summit' (at offset 0xc058b504) and 'apic_bigsmp'
WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_bigsmp' (at offset 0xc058b5a4) and 'cpu.4471'
WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_es7000' (at offset 0xc058b644) and 'apic_default'
WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_default' (at offset 0xc058b6e4) and 'interrupt'
o One of the possible options is to put special case check in MODPOST to
not emit warnings for this case but I think it is not a very good option
in terms of maintenance.
o Another option is to make probe() function non __init. Anyway this function
is really small so not freeing this memory after init is not a big deal.
Secondly, from a programming perspective, probably genapic should not
provide pointers to functions which have been freed as genapic is non
__init and is used even after initialization is complete.
