linux-toradex.git/include/asm-xtensa/page.h, branch v2.6.24.2 Linux kernel for Apalis and Colibri modules [XTENSA] Add support for cache-aliasing 2007-08-27T20:54:16+00:00 Chris Zankel chris@zankel.net 2007-08-22T17:14:51+00:00 6656920b0b50beacb6cb64cf55273cbb686e436e 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] clean-up header files 2007-06-01T00:47:01+00:00 Chris Zankel chris@zankel.net 2007-06-01T00:47:01+00:00 de4f6e5b41bef50fc981410ae8380f27f4e93bf8 The header files in the asm-xtensa directory are not clean and 'make headers_check' fails. This is a first patch to fix most of the header files. It removes unnecessary include statements and adds some that are required for building the kernel. The linker script required some updates or the linking stage would fail. Signed-off-by: Chris Zankel <chris@zankel.net>

[PATCH] xtensa: remove extra header files 2006-12-10T17:55:39+00:00 Chris Zankel czankel@tensilica.com 2006-12-10T10:18:48+00:00 173d6681380aa1d60dfc35ed7178bd7811ba2784 The Xtensa port contained many header files that were never needed. This rather lengthy patch removes all those files. Unfortunately, there were many dependencies that needed to be updated, so this patch touches quite a few source files.
