mm: bring sparc pte_index() semantics inline with other platforms
pte_index() on platforms other than sparc return a numerical index. On
sparc, it returns a pte_t*. This presents an issue for
vm_insert_pages(), which relies on pte_index() to find the offset for a
pte within a pmd, for batched inserts.
This patch:
1. Modifies pte_index() for sparc to return a numerical index, like
other platforms,
2. Defines pte_entry() for sparc which returns a pte_t*
(as pte_index() used to),
3. Converts existing sparc callers for pte_index() to use pte_entry().
[sfr@canb.auug.org.au: remove pte_entry and just directly modified pte_offset_kernel instead]
