[PATCH 4/4] x86/vmlinux.lds.S: take __START_KERNEL out conditional definition
Posted by Wei Yang 1 year, 11 months ago
If CONFIG_X86_32, the section start address is defined to be
"LOAD_OFFSET + LOAD_PHYSICAL_ADDR", which is the same as
__START_KERNEL_map.

Let's take it out to remove the complexity.

x86/vmlinux.lds.S: Take __START_KERNEL out conditional definition

If CONFIG_X86_32=y, the section start address is defined to be
"LOAD_OFFSET + LOAD_PHYSICAL_ADDR", which is the same as
__START_KERNEL_map.

Unify it with the 64-bit definition to simplify the code.
