Once entering machine_halt() and machine_restart(), local_irq_disable()
is called, and local irq is kept disabled, so the local_irq_disable()
at the end of these two functions are not necessary, remove it.

Make virt_to_idmap() return an unsigned long rather than phys_addr_t.
Returning phys_addr_t here makes no sense, because the definition of
virt_to_idmap() is that it shall return a physical address which maps
identically with the virtual address. Since virtual addresses are
limited to 32-bit, identity mapped physical addresses are as well.
Almost all users already had an implicit narrowing cast to unsigned long
so let's make this official and part of this interface.

This patch is to get correct physical address of the reset function for
PAE systems, which use aliased physical memory for booting.
See the "ARM: mm: Introduce virt_to_idmap() with an arch hook" for details.

Move shutdown and reboot related code to a separate file, out of
process.c. This helps to avoid polluting process.c with non-process
related code.
