[XTENSA] Add support for cache-aliasing

2007-08-27T20:54:16+00:00

Add support for processors that have cache-aliasing issues, such as
the Stretch S5000 processor. Cache-aliasing means that the size of
the cache (for one way) is larger than the page size, thus, a page
can end up in several places in cache depending on the virtual to
physical translation. The method used here is to map a user page
temporarily through the auto-refill way 0 and of of the DTLB.
We probably will want to revisit this issue and use a better
approach with kmap/kunmap.

[XTENSA] Add support for executable/non-executable feature in the mmu

2007-08-27T20:54:01+00:00

Newer processor versions starting with Xtensa6/LX2 support an 'executable'
bit for memory pages. This bit replaces the 'valid' bit, so it must be
always set to one for older processor versions. To mark a page invalid, we now
set the cache-attributes to b11, which is backward compatible.

[XTENSA] Fix fadvise64_64

2007-08-27T20:53:32+00:00

Xtensa passes long long arguments in a even/odd register pair,
so we also need to shuffle the arguments when passed through the
system call to avoid an empty argument register.

the getpgrp system-call was missing.
