Subject: [PATCH 1/4] i386: Fix modpost warning in SMP trampoline code
Date: Wed, 3 Jan 2007 17:04:30 +0530 [thread overview]
Message-ID: <20070103113430.GF17546@in.ibm.com> (raw)
o MODPOST generates warning for i386 if kernel is compiled with
CONFIG_RELOCATABLE=y
WARNING: vmlinux - Section mismatch: reference to .init.text:startup_32_smp
from .data between 'trampoline_data' (at offset 0xc0519cf8) and 'boot_gdt'
o trampoline code/data can go into init section is CPU hotplug is not
enabled.
