From: Jonathan Austin <redacted> Set CONFIG_PAGE_OFFSET as PHYS_OFFSET when !MMU so that we can keep CONFIG_PAGE_OFFSET same with PAGE_OFFSET.
I'm not so sure about this commit message - I don't think
it makes sense...Should it not be more like:
------->8-------
Subject: ARM: set PAGE_OFFSET = PHYS_OFFSET if !MMU
With !MMU we still set PAGE_OFFSET to 0xC0000000, which
makes little sense and causes a regression on !MMU after
f6537f2f0eba4eba ("scripts/kallsyms: filter symbols not
kernel address space")
This patch sets PAGE_OFFSET to PHYS_OFFSET in the !MMU
case, fixing the regression (Tested on Cortex-R7/Vexpress)

Russell: Will you pick this patch up from the list or does
it need to go in through the patch system?
