Matt Fleming 3f5ab76816 sh: Correct the PTRS_PER_PMD and PMD_SHIFT values 
The previous expressions were wrong which made free_pmd_range() explode
when using anything other than 4KB pages (which is why 8KB and 64KB
pages were disabled with the 3-level page table layout).

The problem was that pmd_offset() was returning an index of non-zero
when it should have been returning 0. This non-zero offset was used to
calculate the address of the pmd table to free in free_pmd_range(),
which ended up trying to free an object that was not aligned on a page
boundary.

Now 3-level page tables should work with 4KB, 8KB and 64KB pages.
