Subject: i386: modpost smpboot code warning fix
From: Vivek Goyal <vgoyal@xxxxxxxxxx>
o Currently synchronize_tsc_ap() is of type __init. It is called by
smp_callin() which is of type __cpuinit. So synchronize_tsc_ap()
should be of type __cpuinit.
o Modpost generates warnings for i386 if CONFIG_RELOCATABLE=y and
CONFIG_HOTPLUG_CPU=y
WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc01164dc) and 'initialize_secondary'
WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc01164e8) and 'initialize_secondary'
o tsc is of type __initdata. It should be of type __cpuinitdata.
