[PATCH] i386: move startup_32() in text.head section
o Entry startup_32 was in .text section but it was accessing some init data too and it prompts MODPOST to generate compilation warnings. WARNING: vmlinux - Section mismatch: reference to .init.data:boot_params from .text between '_text' (at offset 0xc0100029) and 'startup_32_smp' WARNING: vmlinux - Section mismatch: reference to .init.data:boot_params from .text between '_text' (at offset 0xc0100037) and 'startup_32_smp' WARNING: vmlinux - Section mismatch: reference to .init.data:init_pg_tables_end from .text between '_text' (at offset 0xc0100099) and 'startup_32_smp' o Can't move startup_32 to .init.text as this entry point has to be at the start of bzImage. Hence moved startup_32 to a new section .text.head and instructed MODPOST to not to generate warnings if init data is being accessed from .text.head section. This code has been audited. o SMP boot up code (startup_32_smp) can go into .init.text if CPU hotplug is not supported. Otherwise it generates more warnings WARNING: vmlinux - Section mismatch: reference to .init.data:new_cpu_data from .text between 'checkCPUtype' (at offset 0xc0100126) and 'is486' WARNING: vmlinux - Section mismatch: reference to .init.data:new_cpu_data from .text between 'checkCPUtype' (at offset 0xc0100130) and 'is486' Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Andi Kleen <ak@suse.de>
