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

Hi Jassi,

After merging the mailbox tree, today's linux-next build (powerpc
allyesconfig) failed like this:

In file included from /home/sfr/next/next/include/linux/kvm_host.h:20:0,
                 from /home/sfr/next/next/arch/powerpc/kernel/asm-offsets.c:54:
/home/sfr/next/next/include/linux/msi.h:195:21: fatal error: asm/msi.h: No such file or directory

Caused by commit

  dbc049eee730 ("mailbox: Add driver for Broadcom FlexRM ring manager")

Not all architectures have the above include file.

I have added the following patch for today:
