This fixes a problems with the set up of Linux memory:

 - When reserving memory at boot time, the code previously reserved
   the bottom page of memory, and then from one page up to the end of
   the bootmap. This had the desired effect, but was strictly speaking
   wrong, as the one page was actually whatever CONFIG_ZERO_PAGE_OFFSET
   had been set to.

This fixes a problem in the code which copies the vmalloc portion of the
kernel's page table into the current user space page table. The addition
of the four level page table code breaks on folded page tables, because
the pud level is always present (although folded). This updates the code
to use the same style of updates for the pud as is used for the pgd
level.

This patch fixes a problem within the SH implementation of resume_kernel code,
that implements in assembly the bulk of preempt_schedule_irq function without
taking care of the extra code needed to handle the BKL preemptible.

The patch basically consists of removing this asm code and calling the common
C implementation (see kernel/sched.c) as other archs do.

Another change is the missing 'cli' macro invocation at the beginning of
the resume_kernel.
