      [IA64] 4-level page tables · 837cd0bd
      由 Robin Holt 提交于 
      This patch introduces 4-level page tables to ia64.  I have run
some benchmarks and found nothing interesting.  Performance has
consistently fallen within the noise range.

It also introduces a config option (setting the default to 3
levels).  The config option prevents having 4 level page
tables with 64k base page size.

      [PATCH] PCI: fix for Toshiba ohci1394 quirk · 6e6ece5d
      由 Jesse Barnes 提交于 
      After much testing and agony, I've discovered that my previous ohci1394
quirk for Toshiba laptops is not 100% reliable.  It apparently fails to
do the interrupt line change either correctly or in time, since in about
2 out of 5 boots, the kernel's irqdebug code will *still* disable irq 11
when the ohci1394 driver is loaded (at pci_enable_device time I think).

This patch switches things around a little in the workaround.  First, it
removes the mdelay.  I didn't see a need for it and my testing has shown
that it's not necessary for the quirk to work.

Secondly, instead of trying to change the interrupt line to what ACPI
tells us it should be, this patch makes the quirk use the value in the
PCI_INTERRUPT_LINE register.  On this laptop at least, that seems to be
the right thing to do, though additional testing on other laptops and/or
with actual firewire devices would be appreciated.

      [PATCH] PCI: NCR 53c810 quirk · a5312e28
      由 Ivan Kokshaysky 提交于 
      Move the PPC fixup for old NCR 810 controllers to generic quirks -
it's needed for Alpha, x86 and other architectures that use
setup-bus.c.

Thanks to Jay Estabrook for pointing out the issue.

      [IA64] utilize notify_die() for XPC disengage · 780d09e8
      由 Dean Nelson 提交于 
      XPC (as in arch/ia64/sn/kernel/xp*) has a need to notify other partitions
(SGI Altix) whenever a partition is going down in order to get them to
disengage from accessing the halting partition's memory. If this is not
done before the reset of the hardware, the other partitions can find
themselves encountering MCAs that bring them down.

      [ARM] 3098/1: pxa2xx disable ssp irq · b216c018
      由 Liam Girdwood 提交于 
      Patch from Liam Girdwood

This patch allows users of the pxa SSP driver to register their own irq
handlers instead of using the default SSP handler. It also cleans up the
CKEN clock and irq detection as the values are now stored in a table.

This patch replaces 2845/1

Changes:-
o Added flags parameter to ssp_init()
o Added SSP_NO_IRQ flag to disable registering of ssp irq handler (for
drivers that want to register their own handler)
o Cleaned up clock and irq detection, values are now stored in table.
o Added build changes to allow other drivers (e.g audio) to select the
ssp driver.
o corgi_ssp.c changed to use new interface.

      [ARM] 3096/1: Add SharpSL Zaurus power and battery management core driver · 078abcf9
      由 Richard Purdie 提交于 
      Patch from Richard Purdie

This patch adds a power and battery management core driver which with
the addition of the right device files, supports the c7x0 and cxx00
series of Sharp Zaurus handhelds.

The driver is complex for several reasons. Battery charging is manually
monitored and controlled. When suspended, the device needs to
periodically partially resume, check the charging status and then
re-suspend. It does without bothering the higher linux layers as
a full resume and re-suspend is unnecessary. The code is carefully
written to avoid interrupts or calling code outside the module under
these circumstances. It also vets the various wake up sources and
monitors the device's power situation.

Hooks to limit the backlight intensity and to notify the battery
monitoring code of backlight events are connected/added as the
backlight is one of the biggest users of power on the device.
