Tejun Heo 3ac6cffea4 linker script: use separate simpler definition for PERCPU() ... Impact: fix linker screwup on x86_32 Recent x86_64 zerobased patches introduced PERCPU_VADDR() to put .data.percpu to a predefined address and re-defined PERCPU() in terms of it. The new macro defined one extra symbol, __per_cpu_load, for LMA of the section so that the init data could be accessed. This new symbol introduced the following problems to x86_32. 1. If __per_cpu_load is defined outside of .data.percpu as an absolute symbol, relocation generation for relocatable kernel fails due to absolute relocation. 2. If __per_cpu_load is put inside .data.percpu with absolute address assignment to work around #1, linker gets confused and under certain configurations ends up relocating the symbol against .data.percpu such that the load address gets added on top of already set load address. As x86_32 doesn't use predefined address for .data.percpu, there's no need for it to care about the possibility of __per_cpu_load being different from __per_cpu_start. This patch defines PERCPU() separately so that __per_cpu_load is defined inside .data.percpu so that everything is ordinary linking-wise.
