Subject: Re: [PATCH v4 1/7] m68knommu: Don't hardcode the value of PAGE_SIZE
 in the linker script.

Hi Tim,

This one gives me:

arch/m68knommu/kernel/vmlinux.lds.S:19:1: warning: "BSS" redefined
In file included from arch/m68knommu/kernel/vmlinux.lds.S:10:
include/asm-generic/vmlinux.lds.h:495:1: warning: this is the location 
of the previous definition

A define named "BSS" is already used inside of vmlinux.lds.S.
No big deal, I just changed that internal one.

But otherwise no problems with this patch.

Regards
Greg
