    I am not sure if (1843200 / 16) is suitable for cris, but most other
    arch's define it as this value.

  • After changing all consumers of atomics to include , we
    ran into some compile time errors due to this dependency chain:

    linux/atomic.h
    -> asm/atomic.h
    -> asm-generic/atomic-long.h

    where atomic-long.h could use funcs defined later in linux/atomic.h
    without a prototype. This patches moves the code that includes
    asm-generic/atomic*.h to linux/atomic.h.

    Archs that need need to select
    CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
    unconditionally).

    Compile tested on i386 and x86_64 with allnoconfig.

  • * setns:
    ns: Wire up the setns system call

    Done as a merge to make it easier to fix up conflicts in arm due to
    addition of sendmmsg system call

    Linus Torvalds
     
  • 32bit and 64bit on x86 are tested and working. The rest I have looked
    at closely and I can't find any problems.

    setns is an easy system call to wire up. It just takes two ints so I
    don't expect any weird architecture porting problems.

    While doing this I have noticed that we have some architectures that are
    very slow to get new system calls. cris seems to be the slowest where
    the last system calls wired up were preadv and pwritev. avr32 is weird
    in that recvmmsg was wired up but never declared in unistd.h. frv is
    behind with perf_event_open being the last syscall wired up. On h8300
    the last system call wired up was epoll_wait. On m32r the last system
    call wired up was fallocate. mn10300 has recvmmsg as the last system
    call wired up. The rest seem to at least have syncfs wired up which was
    new in the 2.6.39.

    v2: Most of the architecture support added by Daniel Lezcano
    v3: ported to v2.6.36-rc4 by: Eric W. Biederman
    v4: Moved wiring up of the system call to another patch
    v5: ported to v2.6.39-rc6
    v6: rebased onto parisc-next and net-next to avoid syscall conflicts.
    v7: ported to Linus's latest post 2.6.39 tree.

  • For future rework of try_to_wake_up() we'd like to push part of that
    function onto the CPU the task is actually going to run on.

    In order to do so we need a generic callback from the existing scheduler IPI.

    This patch introduces such a generic callback: scheduler_ipi() and
    implements it as a NOP.

    BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!

    NOTE!

    This merge commit was created to fix compilation error. The block
    tree was merged upstream and removed the 'elv_queue_empty()'
    function which the new 'mtdswap' driver is using. So a simple
    merge of the mtd tree with upstream does not compile. And the
    mtd tree has already be published, so re-basing it is not an option.

    To fix this unfortunate situation, I had to merge upstream into the
    mtd-2.6.git tree without committing, put the fixup patch on top of
    this, and then commit this. The result is that we do not have commits
    which do not compile.

    In other words, this merge commit "merges" 3 things: the MTD tree, the
    upstream tree, and the fixup patch.

  • Percpu allocator honors alignment request upto PAGE_SIZE and both the
    percpu addresses in the percpu address space and the translated kernel
    addresses should be aligned accordingly. The calculation of the
    former depends on the alignment of percpu output section in the kernel
    image.

    The linker script macros PERCPU_VADDR() and PERCPU() are used to
    define this output section and the latter takes @align parameter.
    Several architectures are using @align smaller than PAGE_SIZE breaking
    percpu memory alignment.

    This patch removes @align parameter from PERCPU(), renames it to
    PERCPU_SECTION() and makes it always align to PAGE_SIZE. While at it,
    add PCPU_SETUP_BUG_ON() checks such that alignment problems are
    reliably detected and remove percpu alignment comment recently added
    in workqueue.c as the condition would trigger BUG way before reaching
    there.

    For um, this patch raises the alignment of percpu area. As the area
    is in .init, there shouldn't be any noticeable difference.

    This problem was discovered by David Howells while debugging boot
    failure on mn10300.

  • minix bit operations are only used by minix filesystem and useless by
    other modules. Because byte order of inode and block bitmaps is different
    on each architecture like below:

    m68k:
    big-endian 16bit indexed bitmaps

    h8300, microblaze, s390, sparc, m68knommu:
    big-endian 32 or 64bit indexed bitmaps

    m32r, mips, sh, xtensa:
    big-endian 32 or 64bit indexed bitmaps for big-endian mode
    little-endian bitmaps for little-endian mode

    Others:
    little-endian bitmaps

    In order to move minix bit operations from asm/bitops.h to architecture
    independent code in minix filesystem, this provides two config options.

    CONFIG_MINIX_FS_BIG_ENDIAN_16BIT_INDEXED is only selected by m68k.
    CONFIG_MINIX_FS_NATIVE_ENDIAN is selected by the architectures which use
    native byte order bitmaps (h8300, microblaze, s390, sparc, m68knommu,
    m32r, mips, sh, xtensa). The architectures which always use little-endian
    bitmaps do not select these options.

    Finally, we can remove minix bit operations from asm/bitops.h for all
    architectures.
