Provide support to specify a type of service for a communication identifier. A new function call is used when dealing with IPv4 addresses. For IPv6 addresses, the ToS is specified through the traffic class field in the sockaddr_in6 structure. Signed-off-by:

We can use raw_smp_processor_id() here because the processor ID is only used for debug output and therefore our use is preemption-unsafe. Signed-off-by:

Use Paul's new remap_4k_pfn() function to map our 4K firmware contexts into user space on 64K-page machines without exposing neighboring firmware contexts. Return the context's offset within a 64K page to user space so it can determine the proper virtual address. For details about remap_4k_pfn(), see commit 721151d0 or http://patchwork.ozlabs.org/linuxppc/patch?id=10281Signed-off-by:

These driver changes incorporate the proposed PCI-X / PCI-Express read byte count interface. Reading and setting those values doesn't take place "manually", instead wrapping functions are called to allow quirks for some PCI bridges.

Recover from MSI-X errors by automatically falling back on regular interrupt, instead of asking the user to do this manually. This makes it possible to enable MSI-X by default, and will make it possible to get rid of the msi_x module option in the future. Signed-off-by:

The current IPoIB code might process receive completions from ipoib_drain_cq() when bringing down the interface. This could cause packets to be passed up the stack without the device's poll method being called. Avoid this by setting the status of any successful completions to IB_WC_WR_FLUSH_ERR.

The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg(). Signed-off-by:

This patch fixes a wrong ifdef in the board setup code, leading to the GPIO pin not being pulled high, and thus the USB switch not being powered at all. This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which started in 2005 (before 2.6.12-rc2), then probably because things were working anyway for most people got forgotten. [Ralf: Paolo's original patch didn't fix the module case, Florian's patch only fixed MTX1 etc. so this is a combined patch plus some cleanups.] Cc: Giuseppe Patanè <giuseppe.patane@tvblob.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by:
