  • 4564f9e5f   [PATCH] consolidate line discipline number definitions ... Browse Code »

    The line discipline numbers N_* are currently defined for each architecture
    individually, but (except for a seeming mistake) identically, in
    asm/termios.h. There is no obvious reason why these numbers should be
    architecture specific, nor any apparent relationship with the termios
    structure. The total number of these, NR_LDISCS, is defined in linux/tty.h
    anyway. So I propose the following patch which moves the definitions of
    the individual line disciplines to linux/tty.h too.

    Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
    in the current kernel, but the patch still keeps the complete set in case
    there are plans to use them yet.

  • 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.

    Run this:

    #!/bin/sh
    for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
    echo "De-casting $f..."
    perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
    done

    And then go through and reinstate those cases where code is casting pointers
    to non-pointers.

    And then drop a few hunks which conflicted with outstanding work.

    Pass struct dev pointer to dma_cache_sync()

    dma_cache_sync() is ill-designed in that it does not have a struct device
    pointer argument which makes proper support for systems that consist of a
    mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
    to take a struct device pointer as first argument and fix all its callers
    to pass it.

  • 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.

  • 52393ccc0   [PATCH] remove set_wmb - arch removal ... Browse Code »

    set_wmb should not be used in the kernel because it just confuses the
    code more and has no benefit. Since it is not currently used in the
    kernel this patch removes it so that new code does not include it.

    All archs define set_wmb(var, value) to do { var = value; wmb(); }
    while(0) except ia64 and sparc which use a mb() instead. But this is
    still moot since it is not used anyway.

    Hasn't been tested on any archs but x86 and x86_64 (and only compiled
    tested)

    During the recent discussion of taking 'volatile' off of the spinlock, I

    This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
    sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

  • 22a9835c3   [PATCH] unify PFN_* macros ... Browse Code »

    Just about every architecture defines some macros to do operations on pfns.
    They're all virtually identical. This patch consolidates all of them.

    One minor glitch is that at least i386 uses them in a very skeletal header
    file. To keep away from #include dependency hell, I stuck the new
    definitions in a new, isolated header.

    Of all of the implementations, sh64 is the only one that varied by a bit.
    It used some masks to ensure that any sign-extension got ripped away before
    the arithmetic is done. This has been posted to that sh64 maintainers and
    the development list.

    Compiles on x86, x86_64, ia64 and ppc64.

    Bitmap functions for the minix filesystem and the ext2 filesystem except

  • f348d70a3   [PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notifications ... Browse Code »

    Implement the half-closed devices notifiation, by adding a new POLLRDHUP
    (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the
    existing POLLHUP handling, that does not report correctly half-closed
    devices, was feared to be changed, this implementation leaves the current
    POLLHUP reporting unchanged and simply add a new bit that is set in the few
    places where it makes sense. The same thing was discussed and conceptually
    agreed quite some time ago:

    http://lkml.org/lkml/2003/7/12/116

    Since this new event bit is added to the existing Linux poll infrastruture,
    even the existing poll/select system calls will be able to use it. As far
    as the existing POLLHUP handling, the patch leaves it as is. The
    pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing
    archs and sets the bit in the six relevant files. The other attached diff
    is the simple change required to sys/epoll.h to add the EPOLLRDHUP
    definition.

    There is "a stupid program" to test POLLRDHUP delivery here:

    http://www.xmailserver.org/pollrdhup-test.c

    It tests poll(2), but since the delivery is same epoll(2) will work equally.
