Subject: linux-next: build failure after merge of the arm64 tree

Hi Catalin,

Yesterday's linux-next overnight builds (most arm builds) failed like
this:

./arch/arm/kernel/vmlinux.lds:677: undefined symbol `__hyp_idmap_size' referenced in expression

See, for example,
http://kisskb.ellerman.id.au/kisskb/buildresult/12391163/ . Have a look
at http://kisskb.ellerman.id.au/kisskb/head/8631/ to see the full
carnage :-(

This has been happening for a couple of days and then before that we got:

/opt/cross/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ld:./arch/arm/kernel/vmlinux.lds:544: syntax error

We are using gcc 4.6.3 and binutils 2.22 to do these builds.

I have reverted

12eb3e833961	ARM: kvm: assert on HYP section boundaries not actual code size
e60a1fec44a2	ARM: kvm: implement replacement for ld's LOG2CEIL()
06f75a1f6200	ARM, arm64: kvm: get rid of the bounce page

from linux-next today.  Please address this ASAP.
