    Subject[PATCHv2 0/2] genirq: reliably replay pending edge-triggered irq (plus doc)
    In the following series:

    [1/2] implements the proposal I made at the end of the thread to reliably support replay
    of edge-triggered interrupts on all architectures when using
    disable_irq() / enable_irq().

    Proper replays of pending edge-triggered interrupts was
    depending on CONFIG_HARDIRQS_SW_RESEND which only seems to have
    been noticed for plateforms of ARM and AVR32 architecture while
    it should also have been used on other architectures to get the
    correct behavior. So the patch unconditionally builds the
    resend_irqs() tasklet and its scheduling
    (CONFIG_HARDIRQS_SW_RESEND is not used anymore).

    I only tested an equivalent patch for linux- on powerpc
    for a board with an MPC8555E (using a portC line on the CPM2 PIC),
    and build-tested this one for x86.

    [2/2] updates Documentation/DocBook/genericirq.tmpl, taking
    into account 1/2 other previous undocumented changes to genirq.

    [v2] - Don't touch archs Kconfig and defconfigs
    (CONFIG_HARDIRQS_SW_RESEND is left unused)
    - Don't make unrelated change to a comment in
    - (hopefully) Better commit message for [1/2]
    - Correct spelling errors in [2/2]

    [v1] - initial patch
