Subject: arm: CONFIG_ARM_PATCH_PHYS_VIRT=y is broken on kirkwood

Hi Russel!

I've noticed sheevaplug is not able to boot with
kirkwood_defconfig anymore. After dumb bisection
I've figured out that
    CONFIG_ARM_PATCH_PHYS_VIRT=y
was the problem.

The commit in question is :
> c1becedc8871645278832fabdc6fe138082a495b is the first bad commit
> commit c1becedc8871645278832fabdc6fe138082a495b

>     ARM: enable ARM_PATCH_PHYS_VIRT by default

In order to make the box boot I had to set:
    CONFIG_EMBEDDED=y
    # CONFIG_ARM_PATCH_PHYS_VIRT is not set
   CONFIG_PHYS_OFFSET=0x0

Do you have an idea why it does not boot anymore by default?

Thanks!
