sh: Disable 4kB pages on extended mode TLB. 4kB pages are unstable on extended mode TLB, it's recommended that TLB compat mode be used when using a 4kB PAGE_SIZE. Set the default for extended mode to 8kB. This should have negligible impact, as other than the extra swap cache entry bits, there's no reason to use the extended mode TLB with 4kB pages.
