	All SH-X2 and SH-X3 parts support an extended TLB mode, which has been left as experimental since support was originally merged. Now that it's had some time to stabilize and get some exposure to various platforms, we can drop it as an option and default enable it across the board. This is also good future proofing for newer parts that will drop support for the legacy TLB mode completely. This will also force 3-level page tables for all newer parts, which is necessary both for the varying page sizes and larger memories. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-01-02	sh: Move page table allocation out of line	Matt Fleming	1	-0/+57
	We also switched away from quicklists and instead moved to slab caches. After benchmarking both implementations the difference is negligible. The slab caches suit us better though because the size of a pgd table is just 4 entries when we're using a 3-level page table layout and quicklists always deal with pages.
