In the following series:

[1/2] implements the proposal I made at the end of the thread
http://lkml.org/lkml/2010/4/19/129 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 removes CONFIG_HARDIRQS_SW_RESEND
and unconditionally builds the resend_irqs() tasklet and its
scheduling.

I only tested an equivalent patch for linux-2.6.22.18 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.

When the critical section in handle_edge_irq() is executed after
IRQ_DISABLED has been set in the one in disable_irq(), the interrupt is
acked and masked at controller level and IRQ_PENDING is set.

In order to avoid interrupt loss, an IRQ_PENDING interrupt must be
replayed when enable_irq() is called (or immediately after).

This replay used to be reliable only if:

  * the interrupt controller driver implements a reliable retrigger()
    callback

       or

  * CONFIG_HARDIRQS_SW_RESEND is defined (in this case the flow handler
    can be executed in a tasklet running resend_irqs() )

So CONFIG_HARDIRQS_SW_RESEND was meant to be set on plateforms where it
exists a risk that edge interrupts are used on an interrupt controller
that does not support hard retrigger (or at least not reliably).

But CONFIG_HARDIRQS_SW_RESEND was only defined on arm and avr32
architectures, and other architectures exist which can have controllers
without a reliable retrigger(). Some examples:
 * arch/powerpc/sysdev/cpm2.c arch/powerpc/sysdev/ipic.c
 * arch/blackfin/mach-common/ints-priority.c
 * arch/mips/alchemy/common/irq.c
 * ...

This problem has been made worse since commit:
 76d2160147f43f982dfe881404cfde9fd0a9da21
 genirq: do not mask interrupts by default
which activates the delayed interrupt disable mechanism for every user
of default_disable(). Before, an interrupt could only by missed if
occuring just before masking, and if the critical section of
handle_edge_irq() ran after the one of disable_irq(). But when using the
delayed interrupt disable mechanism, disable_irq() does not mask the
irq, so in this case any edge-triggerd interrupt event occuring between
an effective disable_irq() and the following enable_irq() can be missed
(if neither retrigger() nor CONFIG_HARDIRQS_SW_RESEND is present).

With the present change, resend_irqs() is unconditionally built, so
that edge-triggered interrupts can not be lost.
The CONFIG_HARDIRQS_SW_RESEND option is not used anymore and is removed.

See http://lkml.org/lkml/2010/4/19/129 for the first discussion about
this problem.

   Changing the defconfigs should be a separate patch and I'm not
   going to push such a thing through the genirq tree. The stale
   entries do not hurt.

  That change is unrelated and should be done in a seperate patch.

Thanks,

Ok
In this separate patch, to I put "genirq" in the title?
Do I put it in the same series?

Cheers,

Just keep them out for now and send them to the arch maintainers once
the change hits linus tree.
