      [PATCH] pata: teach ali about rev C8, keep pcmcia driver in sync · a0a00cbf
      由 Alan Cox 提交于 
      This fixes support for rev c8 of the ALi/ULi PATA, and keeps pcmcia in
sync so ide_cs and pata_pcmcia are interchangable, both are only changes
to constants.

Right now rev 0xC8 and higher don't work with libata but 0xc8 is in the
field now.

      [PATCH] cpufreq: make the transition_notifier chain use SRCU · b4dfdbb3
      由 Alan Stern 提交于 
      This patch (as762) changes the cpufreq_transition_notifier_list from a
blocking_notifier_head to an srcu_notifier_head.  This will prevent errors
caused attempting to call down_read() to access the notifier chain at a
time when interrupts must remain disabled, during system suspend.

It's not clear to me whether this is really necessary; perhaps the chain
could be made into an atomic_notifier.  However a couple of the callout
routines do use blocking operations, so this approach seems safer.

The head of the notifier chain needs to be initialized before use; this is
done by an __init routine at core_initcall time.  If this turns out not to
be a good choice, it can easily be changed.

      [PATCH] htirq: tidy up the htirq code · 95d77884
      由 Eric W. Biederman 提交于 
      This moves the declarations for the architecture helpers into
include/linux/htirq.h from the generic include/linux/pci.h.  Hopefully this
will make this distinction clearer.

htirq.h is included where it is needed.

The dependency on the msi code is fixed and removed.

The Makefile is tidied up.

      [PATCH] msi: refactor and move the msi irq_chip into the arch code · 3b7d1921
      由 Eric W. Biederman 提交于 
      It turns out msi_ops was simply not enough to abstract the architecture
specific details of msi.  So I have moved the resposibility of constructing
the struct irq_chip to the architectures, and have two architecture specific
functions arch_setup_msi_irq, and arch_teardown_msi_irq.

For simple architectures those functions can do all of the work.  For
architectures with platform dependencies they can call into the appropriate
platform code.

With this msi.c is finally free of assuming you have an apic, and this
actually takes less code.

The helpers for the architecture specific code are declared in the linux/msi.h
to keep them separate from the msi functions used by drivers in linux/pci.h

      [PATCH] msi: only use a single irq_chip for msi interrupts · 277bc33b
      由 Eric W. Biederman 提交于 
      The logic works like this.

Since we no longer track the state logic by hand in msi.c startup and shutdown
are no longer needed.

By updating msi_set_mask_bit to work on msi devices that do not implement a
mask bit we can always call the mask/unmask functions.

What we really have are mask and unmask so we use them to implement the .mask
and .unmask functions instead of .enable and .disable.

By switching to the handle_edge_irq handler we only need an ack function that
moves the irq if necessary.  Which removes the old end and ack functions and
their peculiar logic of sometimes disabling an irq.

This removes the reliance on pre genirq irq handling methods.
