Removed the unused Xtal_Int variable. That made it also possible to remove a

The conversion to per bus type registration functions means we don't need
to do module_get()s to hold the bus types in memory (their users will link
to them) so we removed all those calls. This left module_put() calls in
the cleanup paths which aren't needed and which cause unbalanced puts if
we ever try to unload anything.

As it was decided not to export struct pt_regs to userspace, struct
sigcontext shouldn't be using it either. The pt_regs struct for OpenRISC
is kernel internal and the layout of the registers may change in the
future. The struct user_regs_struct is what is guaranteed to remain
stable, so struct sigcontext may use that instead.
This patch removes the usage of struct pt_regs in struct sigcontext and
makes according changes in signal.c to get the register layout right.
The usp field is removed from the sigcontext structure as this information
is already contained in the user_regs_struct.

When ARCH_HAS_HOLES_MEMORYMODEL is selected, pfn_valid calls
memblock_is_memory to test validity of a pfn:
> memblock_is_memory(pfn << PAGE_SHIFT);
On LPAE systems this cuts off the top bits, as the shift occurs before
the value is promoted to a phys_addr_t.
This patch replaces the shift with a call to __pfn_to_phys (which casts
pfn to phys_addr_t before shifting), preventing the loss of significant
bits.
