  • …-2.6 into next/cleanup

    From Shawn Guo:
    The series cleans up ARCH_HAS_DECOMP_WDOG and arch_decomp_wdog which
    are unused on ARM architecure. Samsung has some code setting up wdog
    in arch_decomp_wdog(). But since CONFIG_S3C_BOOT_WATCHDOG is defined
    nowhere, it will not run. Otherwise, system can not boot at all when
    wdog is set up but no one pats it.

    * tag 'cleanup-decompwdog-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6:
    ARM: samsung: remove unused arch_decomp_wdog() code

  • Now that the only field in struct sys_timer is .init, delete the struct,
    and replace the machine descriptor .timer field with the initialization
    function itself.

    This will enable moving timer drivers into drivers/clocksource without
    having to place a public prototype of each struct sys_timer object into
    include/linux; the intent is to create a single of_clocksource_init()
    function that determines which timer driver to initialize by scanning
    the device dtree, much like the proposed irqchip_init() at:
    http://www.spinics.net/lists/arm-kernel/msg203686.html

    Includes mach-omap2 fixes from Igor Grinberg.

  • remove ARM's struct sys_timer .offset function pointer, and instead
    directly set the arch_gettimeoffset function pointer when the timer
    driver is initialized. This requires multiplying all function results
    by 1000, since the removed arm_gettimeoffset() did this. Also,
    s/unsigned long/u32/ just to make the function prototypes exactly
    match that of arch_gettimeoffset.

    Pull "Disintegrate and delete asm/system.h" from David Howells:
    "Here are a bunch of patches to disintegrate asm/system.h into a set of
    separate bits to relieve the problem of circular inclusion
    dependencies.

    I've built all the working defconfigs from all the arches that I can
    and made sure that they don't break.

    The reason for these patches is that I recently encountered a circular
    dependency problem that came about when I produced some patches to
    optimise get_order() by rewriting it to use ilog2().

    This uses bitops - and on the SH arch asm/bitops.h drags in
    asm-generic/get_order.h by a circuituous route involving asm/system.h.

    The main difficulty seems to be asm/system.h. It holds a number of
    low level bits with no/few dependencies that are commonly used (eg.
    memory barriers) and a number of bits with more dependencies that
    aren't used in many places (eg. switch_to()).

    These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

    Move memory barriers here. This already done for MIPS and Alpha.

    (2) asm/switch_to.h

    Move switch_to() and related stuff here.

    (3) asm/exec.h

    Move arch_align_stack() here. Other process execution related bits
    could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

    Move xchg() and cmpxchg() here as they're full word atomic ops and
    frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

    Move die() and related bits.

    (6) asm/auxvec.h

    Move AT_VECTOR_SIZE_ARCH here.

    Other arch headers are created as needed on a per-arch basis."

    Fixed up some conflicts from other header file cleanups and moving code
    around that has happened in the meantime, so David's testing is somewhat
    weakened by that. We'll find out anything that got broken and fix it..

  • Pull ARM platform updates from Russell King:
    "This covers platform stuff for platforms I have a direct interest in
    (iow, I have the hardware). Essentially:
    - as we no longer support any other Acorn platforms other than RiscPC
    anymore, we can collect all that code into mach-rpc.
    - convert Acorn expansion card stuff to use IRQ allocation functions,
    and get rid of NO_IRQ from there.
    - cleanups to the ebsa110 platform to move some private stuff out of
    its header files.
    - large amount of SA11x0 updates:
    - conversion of private DMA implementation to DMA engine support
    (this actually gives us greater flexibility in drivers over the old
    API.)
    - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
    dependencies, fix various minor issues
    - move platform specific sa11x0 framebuffer data into platform files
    in arch/arm instead of keeping this in the driver itself
    - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
    for SIR transmissions as well as FIR
    - rework sa1111 support for genirq, and irq allocation
    - fix sa1111 IRQ support so it works again
    - use sparse IRQ support

    After this, I have one more pull request remaining from my current
    set, which I think is going to be the most problematical as it
    generates 8 conflicts."

  • We only need to set the system up for a soft-restart if we're going to
    be doing a soft-restart. Provide a new function (soft_restart()) which
    does the setup and final call for this, and make platforms use it.
    Eliminate the call to setup_restart() from the default handler.

    This means that platforms arch_reset() function is no longer called with
    the page tables prepared for a soft-restart, and caches will still be
    enabled.

  • Some platforms (like OMAP not to name it) are doing rather complicated
    hacks just to determine the base UART address to use. Let's give their
    addruart macro some slack by providing an extra work register which will
    allow for much needed cleanups.

    This is basically a no-op as this commit is only adding the extra argument
    to the macro but no one is using it yet.

  • Rather than checking the MMU status in every instance of addruart, do it
    once in kernel/debug.S, and change the existing addruart macros to
    return both physical and virtual addresses. The main debug code can then
    select the appropriate address to use.

    This will also allow us to retreive the address of a uart for the MMU
    state that we're not current in.

  • VMALLOC_END is supposed to be an absolute value, while PAGE_OFFSET may
    vary depending on the selected user:kernel memory split mode through
    CONFIG_VMSPLIT_*. In fact, the goal of moving PAGE_OFFSET down is to
    accommodate more directly addressed RAM by the kernel below the vmalloc
    area, and having VMALLOC_END move along PAGE_OFFSET is rather against
    the very reason why PAGE_OFFSET can be moved in the first place.
