[PATCH 0/2] Allow nesting of lazy MMU mode

Dave Woodhouse reported that we now nest calls to
arch_enter_lazy_mmu_mode().  That was inadvertent, but in principle we
should allow it.  On further investigation, Juergen already fixed it
for Xen, but didn't tell anyone.  Fix it for Sparc & PowerPC too.
This may or may not help fix the problem that Erhard reported.
