Commit 65dd74a674d6 (x86: ivybridge: Implement SDRAM init) introduced x86-specific asmlinkage into arch/x86/include/asm/config.h. Commit ed0a2fbf14f7 (x86: Add a definition of asmlinkage) added the same macro define again, this time, into include/common.h. (Please do not add arch-specific stuff to include/common.h any more; it is already too cluttered.) The generic asmlinkage is defined in <linux/linkage.h>. If you want to override it with an arch-specific one, the best way is to add it to <asm/linkage.h> like Linux Kernel.
