Subject: linux-next: build failure after merge of the akpm-current tree
Hi Andrew,
After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit
4382eb9055be ("kexec: allow architectures to override boot mapping")
Architecture seem to define phys_to_virt() in either asm/io.h or
asm/memory.h or asm/virtconvert.h or asm/page*.h ... or asm-generic/io.h.
:-(
I have reverted that commit for today (and commit c9aaeae038fa ("ARM:
kexec: fix kexec for Keystone 2")).
