  • 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.

  • 01858d1b0   [XTENSA] Add support for executable/non-executable feature in the mmu ... Browse Code »

    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.

    Kill pte_rdprotect(), pte_exprotect(), pte_mkread(), pte_mkexec(), pte_read(),
    pte_exec(), and pte_user() except where arch-specific code is making use of
    them.

  • 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.

  • 46a82b2d5   [PATCH] Standardize pxx_page macros ... Browse Code »

    One of the changes necessary for shared page tables is to standardize the
    pxx_page macros. pte_page and pmd_page have always returned the struct
    page associated with their entry, while pte_page_kernel and pmd_page_kernel
    have returned the kernel virtual address. pud_page and pgd_page, on the
    other hand, return the kernel virtual address.

    Shared page tables needs pud_page and pgd_page to return the actual page
    structures. There are very few actual users of these functions, so it is
    simple to standardize their usage.

    Since this is basic cleanup, I am submitting these changes as a standalone
    patch. Per Hugh Dickins' comments about it, I am also changing the
    pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

  • 8c65b4a60   [PATCH] fix remaining missing includes ... Browse Code »

    Fix more include file problems that surfaced since I submitted the previous
    fix-missing-includes.patch. This should now allow not to include sched.h
    from module.h, which is done by a followup patch.
