sh: Preliminary support for SH-X2 MMU.
This adds some preliminary support for the SH-X2 MMU, used by newer SH-4A parts (particularly SH7785). This MMU implements a 'compat' mode with SH-X MMUs and an 'extended' mode for SH-X2 extended features. Extended features include additional page sizes (8kB, 4MB, 64MB), as well as the addition of page execute permissions. The extended mode attributes are placed in a second data array, which requires us to switch to 64-bit PTEs when in X2 mode. With the addition of the exec perms, we also overhaul the mmap prots somewhat, now that it's possible to handle them more intelligently. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
