  • 177cf6e52   clocksources: Switch back to the clksrc table ... Browse Code »

    All the clocksource drivers's init function are now converted to return
    an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
    clksrc-of table.

    Let's convert back the names:
    - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
    - clksrc-of-ret => clksrc-of

  • 1ee078fac   clocksource/drivers/u300: Convert init function to return error ... Browse Code »

    The init functions do not return any error. They behave as the following:

    - panic, thus leading to a kernel crash while another timer may work and
    make the system boot up correctly

    or

    - print an error and let the caller unaware if the state of the system

    Change that by converting the init functions to return an error conforming
    to the CLOCKSOURCE_OF_RET prototype.

    Proper error handling (rollback, errno value) will be changed later case
    by case, thus this change just return back an error or success in the init
    function.

  • 8ff8fc13b   clockevents/drivers/u300: Migrate to new 'set-state' interface ... Browse Code »

    Migrate u300 driver to the new 'set-state' interface provided by
    clockevents core, the earlier 'set-mode' interface is marked obsolete
    now.

    This also enables us to implement callbacks for new states of clockevent
    devices, for example: ONESHOT_STOPPED.

    Pull ARM changes from Russell King:

    - Perf updates from Will Deacon:
    - Support for Qualcomm Krait processors (run perf on your phone!)
    - Support for Cortex-A12 (run perf stat on your FPGA!)
    - Support for perf_sample_event_took, allowing us to automatically decrease
    the sample rate if we can't handle the PMU interrupts quickly enough
    (run perf record on your FPGA!).

    - Basic uprobes support from David Long:
    This patch series adds basic uprobes support to ARM. It is based on
    patches developed earlier by Rabin Vincent. That approach of adding
    hooks into the kprobes instruction parsing code was not well received.
    This approach separates the ARM instruction parsing code in kprobes out
    into a separate set of functions which can be used by both kprobes and
    uprobes. Both kprobes and uprobes then provide their own semantic action
    tables to process the results of the parsing.

    - ARMv7M (microcontroller) updates from Uwe Kleine-König

    - OMAP DMA updates (recently added Vinod's Ack even though they've been
    sitting in linux-next for a few months) to reduce the reliance of
    omap-dma on the code in arch/arm.

    - SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan

    - Support for Cortex-A12 CPU

    - Align support for ARMv6 with ARMv7 so they can cooperate better in a
    single zImage.

    - Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support.

    - Removal of IRQ_DISABLED from various ARM files

    - Improved efficiency of virt_to_page() for single zImage

    - Patch from Ulf Hansson to permit runtime PM callbacks to be available for
    AMBA devices for suspend/resume as well.

    - Finally kill asm/system.h on ARM.
