      [PATCH] PCI: Clear abnormal poweroff flag on VIA southbridges, fix resume · 709cf5ea
      由 Matthew Garrett 提交于 
      Some VIA southbridges contain a flag in the ACPI register space that
indicates whether an abnormal poweroff has occured, presumably with the
intention that it can be cleared on clean shutdown.  Some BIOSes check this
flag at resume time, and will re-POST the system rather than jump back to
the OS if it's set.  Clearing it at boot time appears to be sufficient.
I'm not sure if drivers/pci/quirks.c is the right place to do it, but I'm
not sure where would be cleaner.

      [PATCH] ide: fix Jmicron support · 15e0c694
      由 Alan Cox 提交于 
      Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.

To fix this three things are needed.

#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports

The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.

The actual chip setup done by the quirk is the precise setup recommended
by the vendor.

(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

      [PATCH] msi: Only keep one msi_desc in each slab entry. · ec572e3f
      由 Eric W. Biederman 提交于 
      It looks like someone confused kmem_cache_create with a different allocator
and was attempting to give it knowledge of how many cache entries there
were.

With the unfortunate result that each slab entry was big enough to hold
every irq.

      Add PIIX4 APCI quirk for the 440MX chipset too · c6764664
      由 Linus Torvalds 提交于 
      This is confirmed to fix a hang due to PCI resource conflicts with
setting up the Cardbus bridge on old laptops with the 440MX chipsets.
Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:

  "From the docs available i would _guess_ this thing is really similar
   to the 82443BX/82371AB combination.  at least the SMBus base address
   register is hidden at the very same place (32bit at 0x90 in function
   3 of the "south" brigde)"

The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:

  "I am trying to find the register information. 440MX is an integration of
   440BX north-bridge without AGP and PIIX4E (82371EB).  PIIX4 quirk
   should cover the ACPI and SMBus related I/O registers."

and verified to fix the problem by Alessio.

      [PATCH] pci: initialize struct pci_dev.error_state · 82081797
      由 Linas Vepstas 提交于 
      The pci channel state is currently uninitialized, thus there are two ways
of indicating that "everything's OK": 0 and 1.  This is a bit of a burden.

If a devce driver wants to check if the pci channel is in a working or a
disconnected state, the driver writer must perform checks similar to

   if((pdev->error_state != 0) &&
      (pdev->error_state != pci_channel_io_normal)) {
         whatever();
   }

which is rather akward.  The first check is needed because stuct pci_dev is
inited to all-zeros.  The scond is needed because the error recovery will
set the state to pci_channel_io_normal (which is not zero).

This patch fixes this awkwardness.

      [PATCH] don't select CONFIG_HOTPLUG · 135c294f
      由 Andrew Morton 提交于 
      It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing
and for section-checking coverage.  But a few things go and select
CONFIG_HOTPLUG, making it a royal PITA to turn the thing off.

It's only turnable offable if CONFIG_EMBEDDED anyway.  So let's make those
things depend on HOTPLUG, not select it.

      [PATCH] genirq: rename desc->handler to desc->chip · d1bef4ed
      由 Ingo Molnar 提交于 
      This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.

While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.

The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.

This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.

As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.

The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.

We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.

This patch:

rename desc->handler to desc->chip.

Originally i did not want to do this, because it's a big patch.  But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.

I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.

So lets get over with this quickly.  The conversion was done automatically
via scripts and converts all the code in the kernel.

This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.

      [PATCH] x86_64: msi_apic.c build fix · a4cffb64
      由 Christian Kujau 提交于 
            CC      drivers/pci/msi-apic.o
In file included from include/asm/msi.h:11,
                  from drivers/pci/msi.h:71,
                  from drivers/pci/msi-apic.c:8:
include/asm/smp.h:103: error: syntax error before '->' token

akpm: nasty.  It appears to be

  static inline unsigned int cpu_mask_to_apicid(cpumask_t cpumask)

conflicting with include/asm-x86_64/mach_apic.h's

  #define cpu_mask_to_apicid (genapic->cpu_mask_to_apicid)

And I don't know which patch in rc4-mm1 triggered this.

Fixing this in the .c file seems wrong.

Including asm/smp.h instead of linux/smp.h seems wrong too.  Need that
.config.
