      [PATCH] Validate ACPI CPU frequency values · a71d72ce
      Dominik Brodowski authored
      This is a simple fix for some of the problems with bad ACPI frequency values:
      
        Abort if the frequency field in _PSS is zero, as we're having a
        completely broken ACPI table then.
      
      A more complete overhaul of the acpi-cpufreq driver (where the cause of
      the problem lies) is in the latest acpi-test tree, but that's definitely
      something to be delayed for 2.6.3 -- and the same is true for the
      yet-to-be-written do_div64 conversion.

      [PATCH] [APM] Is this the correct way to fix suspend bug introduced · 87903ac5
      Michael Schierl authored
      This fixes my APM problems (without them my laptop, Acer TravelMate
      210TEV (Celeron 700, 128 MB RAM), hangs after resuming from APM since
      2.6.0-test4).
      
      Modified based on comments from Pavel Machek <pavel@suse.cz>, who
      has acked the updated patch.

      [PATCH] PCI: name length change · 6a1bd126
      Kieran Morrissey authored
      - Changes gen-devlist.c to truncate long device names rather than reject
        the database
      - Changes PCI_NAME_SIZE to 96 (and PCI_NAME_HALF to 43) to allow all
        current pci.ids names to fit
      - Modifies gen-devlist.c to truncate at 89 characters rather than 79 -
        allows for two digit instance numbers to be added to the name as well
        while staying within the 96 characters allocated. No names in the
        current pci.ids are any longer than this.
      - Modifies names.c to no longer limit device name length when displaying
        both vendor and device name; the truncation is done by gen-devlist.c.

      [PATCH] PCI Hotplug: add address file and fix acpiphp bugs · 272b06a8
      Takayoshi Kochi authored
      This is the pending patch that adds 'address' file to show
      PCI-address and a few other minor fixes.
      As 2.6.0 is out, I'm resending the patch.
      Would you mind taking this?

      [PATCH] PCI: add pci_get_slot() function · 9648e089
      Matthew Wilcox authored
      tg3.c has a bug where it can find the wrong 5704 peer on a machine with
      PCI domains.  The problem is that pci_find_slot() can't distinguish
      whether it has the correct domain or not.
      
      This patch fixes that problem by introducing pci_get_slot().

      [PATCH] PCI Hotplug: Better reporting of PCI frequency / bus mode problems for acpi driver · 78d65a24
      Matthew Wilcox authored
      When plugging a 33MHz card into a bus that's running at 66MHz, I'd like
      to see a better error message than:
      
      acpiphp_glue: notify_handler: unknown event type 0x5 for \_SB_.SBA0.PCI4.S2F0
      
      The following patch would give us:
      
      Device \_SB_.SBA0.PCI4.S2F0 cannot be configured due to a frequency mismatch
      
      which I think is clearer.

      [PATCH] Prevent PCI driver registration failure oopsing · b5849a35
      Russell King authored
      Greg,
      
      As discussed about six or so months ago, we agreed to hold off this
      patch until fairly late, due to its ability to catch duplicate PCI
      driver names.  Please note that I haven't attempted to reproduce the
      problem with recent kernels, and that all ARM kernel patches released
      since then have had this patch in.
      
      I'm guessing this will actually be 2.6.1 material since it probably
      doesn't show for PCI drivers which are part of the kernel tree.
      
      
      If pci_register_driver fails, the register the PCI driver structure
      will not be registered with the driver model.  pci_register_driver
      returns with negative value, and we then attempt to unregister the
      driver structure.  This leads to an oops in the driver model.
      
      The driver model does not return the number of devices it successfully
      bound the driver to, and neither does pci_register_driver() return
      this information.
      
      Therefore, all of the code below is redundant.
      
      (There's a little redundancy left in drivers/pci/pci-driver.c but it
      is harmless unlike this block.)
