LMB build failure in -next

[Mark Brown]

In -next the patch 'ARM: initial LMB trial' is causing build failures:

  CHECK   arch/arm/kernel/setup.c
arch/arm/kernel/setup.c:30:11: error: unable to open 'linux/lmb.h'

for me.  Looks like the generic header got missed from the commit or
there's some other tree that also needs to be in -next?
