  • 6656920b0   [XTENSA] Add support for cache-aliasing ... Browse Code »

    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.

  • ec8c0446b   [PATCH] Optimize D-cache alias handling on fork ... Browse Code »

    Virtually index, physically tagged cache architectures can get away
    without cache flushing when forking. This patch adds a new cache
    flushing function flush_cache_dup_mm(struct mm_struct *) which for the
    moment I've implemented to do the same thing on all architectures
    except on MIPS where it's a no-op.

  • 173d66813   [PATCH] xtensa: remove extra header files ... Browse Code »

    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.
