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) --------8<---------
I like this commit log better, too. As CONFIG_PAGE_OFFSET is only used in scripts/kallsyms.c and scripts/link-vmlinux.sh for !MMU. Booting on efm32 with this patch works just fine, so if you want add my Tested-by. But I'm unsure how valuable it is as I don't see a breakage without it.
