Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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>
