[PATCH] ia64: fix a few section mismatch warnings

[Sam Ravnborg <sam@ravnborg.org>]

Fix the following section mismatch warnings:

WARNING: vmlinux.o(.text+0x41902): Section mismatch: reference to .init.text:__alloc_bootmem (between 'ia64_mca_cpu_init' and 'ia64_do_tlb_purge')
WARNING: vmlinux.o(.text+0x49222): Section mismatch: reference to .init.text:__alloc_bootmem (between 'register_intr' and 'iosapic_register_intr')
WARNING: vmlinux.o(.text+0x62beb2): Section mismatch: reference to .init.text:__alloc_bootmem_node (between 'hubdev_init_node' and 'cnodeid_get_geoid')

For two of the warnings a helper function marked __init_refok was used.
For the last warning a missing __init annotation was added.

The two remaning warnings in the defconfig build I could not fix:
WARNING: vmlinux.o(.text+0x5b0e2): Section mismatch: reference to .init.text:memmap_init_zone (between 'virtual_memmap_init' and 'memmap_init')
WARNING: vmlinux.o(.text+0x5b182): Section mismatch: reference to .init.text:memmap_init_zone (between 'memmap_init' and 'find_max_min_low_pfn')

I was not sure about the right way to do it since I did not understand
the code in mm/init.c deeply enough.
