    [AVR32] Ignore a few irrelevant syscalls
    
    Ignore a few syscalls that are irrelevant because they're either old,
    depends on NUMA or depends on SMP.

    [AVR32] SMC configuration in clock cycles
    
    This patch makes the SMC configuration take timings in clock cycles
    instead of nanoseconds. A function to calculate timings in clock
    cycles is added.
    
    This patch removes the rounding troubles of the previous SMC
    configuration method.

    [AVR32] Drop support for redundant "keepinitrd" boot-time parm.
    
    Given the existing "retain_initrd" boot-time parameter defined in
    init/initramfs.c, there appears to be no need for the equivalent
    "keepinitrd" parameter.

    [AVR32] Make dma_sync_*_for_cpu no-ops
    
    I don't think the dma_sync_*_for_cpu ever did anything useful. We
    flush the relevant cache lines when mapping the buffer or when calling
    dma_sync_*_for_device(), and the CPU isn't allowed to touch the buffer
    after that.
    
    In other words, if these functions actually have anything to flush
    from the caches, we're already in trouble.

commit ed029658a0653f26a85e7111c147f53f7ce95c20
Author: Haavard Skinnemoen <hskinnemoen@atmel.com>
Date:   Mon Sep 17 11:13:45 2007 +0200

    [AVR32] Remove unneeded 8K alignment of .text section
    
    __init_end, which comes immediately before .text, is already page
    aligned, and that should be more than enough for the .text section.
    
    The reason why we need to align the .text section is because the
    interrupt handler offset is ORed with EVBA, so we need to provide
    enough alignment of EVBA that this OR operation works as an ADD.
    
    Currently, the last interrupt handler is not nearly a full page away
    from EVBA, so it won't be a problem.
