Skip ISA ioresource alignment on some systems To conserve limited PCI i/o resource on some IBM multi-node systems, the BIOS allocates (via _CRS) and expects the kernel to use addresses in ranges currently excluded by pcibios_align_resource() [i386/pci/i386.c]. This change allows the kernel to use the currently excluded address ranges on the IBM x3800, x3850, and x3950. Signed-off-by:

Remove transparent bridge sizing. Due to code in pci_read_bridge_bases() [drivers/pci/probe.c] the child bus of a transparent bridge already has access to the parent bus resources so transparent bridge sizing appears unnecessary. The bridge sizing includes alignment and granularity adjustments that can cause significantly more memory to be reserved from the parant bus than required by devices on the child bus and allotted by _CRS.

When a /proc/bus/pci file is written to, the size of that PCI device's configuration space must be written to the inode. Otherwise, it is possible for the file to specify a size of 0 on stat if a task is holding the same file open. Signed-off-by:

On pci_proc_attach_device(), the size of the PCI configuration space is stored in the proc_dir_entry as the size of the file. Thus, the procfs interface to PCI devices should use it instead of the device directly. Signed-off-by:

The code for dynamically assigning new ids to PCI drivers, store_new_id(), calls list_add_tail() with the list head and new node arguments in reversed order. The result is that every new id written essentially overwrites the previous list of ids.

On the "MSI K8T Neo2-FIR" board the BIOS disables the onboard soundcard, if a second PCI soundcard is present. This patch sets the korrect register bit to enable the onboard sound. Removed old code in /drivers/pci/quirks.c that only checks for the PCI-ID and fires on any Board with VIA 8237. New code in /arch/i386/pci/fixup.c checks the DMI-tables and only runs on the specific board. Signed-off-by:

Add support for PicoPower PT86C523 IRQ router to be used with the in-kernel yenta driver for CardBus. With this patch cardbus works on e.g. Dell Latitude XPi P150CD. Initial patch for kernel 2.4 series by Sune Mølgaard http://molgaard.org/code/linux-2.4.31-picopower.patch Ported to 2.6.20 by Chmouel Boudjnah (http://www.chmouel.com) Testing and confirmation that it works by Austin Acton Cleaned up a little for inclusion in a 2.6.21-rc7 based kernel. Added some more cleanups according to CodingStyle, as noted by Randy Dunlap on LKML. [akpm@linux-foundation.org: build fixes] Signed-off-by:

On at least ARM (and I'm told MIPS too) dma_free_coherent() has a newish call context requirement: unlike its dma_alloc_coherent() sibling, it may not be called with IRQs disabled. (This was new behavior on ARM as of late 2005, caused by ARM SMP updates.) This little surprise can be annoyingly driver-visible. Since it looks like that restriction won't be removed, this patch changes the definition of the API to include that requirement. Also, to help catch nonportable drivers, it updates the x86 and swiotlb versions to include the relevant warnings. (I already observed that it trips on the bus_reset_tasklet of the new firewire_ohci driver.) Signed-off-by:
