  • f8829caee   [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page ... Browse Code »

    The current implementation uses a sequence of a cacheflush and a copy.
    This is racy in case of a multithreaded debuggee and renders GDB
    virtually unusable.

    Aside this fixes a performance hog rendering access to /proc/cmdline very
    slow and resulting in a enough cache stalls for the 34K AP/SP programming
    model to make the bare metal code on the non-Linux VPE miss RT deadlines.

    The main part of this patch was originally written by Ralf Baechle;
    Atushi Nemoto did the the debugging.

  • f7a849153   [MIPS] Fix FIXADDR_TOP for TX39/TX49. ... Browse Code »

    FIXADDR_TOP is used for HIGHMEM and for upper limit of vmalloc area on
    32bit kernel. TX39XX and TX49XX have "reserved" segment in CKSEG3
    area. 0xff000000-0xff3fffff on TX49XX and 0xff000000-0xfffeffff on
    TX39XX are reserved (unmapped, uncached) therefore can not be used as
    mapped area.

    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!
