  • ce816fa88   Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP ... Browse Code »

    If the renamed symbol is defined lib/iomap.c implements ioport_map and
    ioport_unmap and currently (nearly) all platforms define the port
    accessor functions outb/inb and friend unconditionally. So
    HAS_IOPORT_MAP is the better name for this.

    Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

    The motivation for this change is to reintroduce a symbol HAS_IOPORT
    that signals if outb/int et al are available. I will address that at
    least one merge window later though to keep surprises to a minimum and
    catch new introductions of (HAS|NO)_IOPORT.

    The changes in this commit were done using:

    $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

    Pull tracing updates from Steven Rostedt:
    "Most of the changes were largely clean ups, and some documentation.
    But there were a few features that were added:

    Uprobes now work with event triggers and multi buffers and have
    support under ftrace and perf.

    The big feature is that the function tracer can now be used within the
    multi buffer instances. That is, you can now trace some functions in
    one buffer, others in another buffer, all functions in a third buffer
    and so on. They are basically agnostic from each other. This only
    works for the function tracer and not for the function graph trace,
    although you can have the function graph tracer running in the top
    level buffer (or any tracer for that matter) and have different
    function tracing going on in the sub buffers"

  • 05d58f607   tile PCI RC: Use default pcibios_enable_device() ... Browse Code »

    We don't need anything arch-specific in pcibios_enable_device(), so drop
    the arch implementation and use the default generic one.

    Note: pci_enable_resources() checks that r->parent is non-NULL, which
    basically checks that pci_claim_resource() or request_resource() has been
    called for each BAR. I don't see where that happens for tile, but this
    patch doesn't change that behavior, so if it worked before, it should still
    work.

    As the data parameter is not really used by any ftrace_dyn_arch_init,
    remove that from ftrace_dyn_arch_init. This also removes the addr
    local variable from ftrace_init which is now unused.

    No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any
    way, it just sets the value to 0. And this is used as a return value
    in the caller -- ftrace_init, which just checks the retval against
    zero.

    Note there is also "return 0" in every ftrace_dyn_arch_init. So it is
    enough to check the retval and remove all the indirect sets of data on
    all archs.

  • 5a5e75f47   tile: remove compat_sys_lookup_dcookie declaration to fix compile error ... Browse Code »

    With commit d8d14bd09cdd ("fs/compat: fix lookup_dcookie() parameter
    handling") I changed the type of the len parameter of the
    lookup_dcookie() syscall.

    However I missed that there was still a stale declaration in
    arch/tile/.. which now causes a compile error on tile:

    In file included from fs/dcookies.c:28:0:
    include/linux/compat.h:425:17: error: conflicting types for 'compat_sys_lookup_dcookie'
    fs/dcookies.c:207:1: error: conflicting types for 'compat_sys_lookup_dcookie'

    Simply remove the declaration in the tile architecture, which is only a
    leftover from before the different compat lookup_dcookie() versions have
    been merged. The correct declaration is now in include/linux/compat.h

    The build error was reported by Fenguang's build bot.

  • 93ea02bb8   arch: Clean up asm/barrier.h implementations using asm-generic/barrier.h ... Browse Code »
    17

    We're going to be adding a few new barrier primitives, and in order to
    avoid endless duplication make more agressive use of
    asm-generic/barrier.h.

    Change the asm-generic/barrier.h such that it allows partial barrier
    definitions and fills out the rest with defaults.

    There are a few architectures (m32r, m68k) that could probably
    do away with their barrier.h file entirely but are kept for now due to
    their unconventional nop() implementation.

    Pull irq cleanups from Ingo Molnar:
    "This is a multi-arch cleanup series from Thomas Gleixner, which we
    kept to near the end of the merge window, to not interfere with
    architecture updates.

    This series (motivated by the -rt kernel) unifies more aspects of IRQ
    handling and generalizes PREEMPT_ACTIVE"

  • f862eefec   tile: use a more conservative __my_cpu_offset in CONFIG_PREEMPT ... Browse Code »

    It turns out the kernel relies on barrier() to force a reload of the
    percpu offset value. Since we can't easily modify the definition of
    barrier() to include "tp" as an output register, we instead provide a
    definition of __my_cpu_offset as extended assembly that includes a fake
    stack read to hazard against barrier(), forcing gcc to know that it
    must reread "tp" and recompute anything based on "tp" after a barrier.

    This fixes observed hangs in the slub allocator when we are looping
    on a percpu cmpxchg_double.

    A similar fix for ARMv7 was made in June in change 509eb76ebf97.
