2012-10-03mlx4_core: Adjust flow steering attach wrapper so that IB works on SR-IOV VFsJack Morgenstein
Currently, the InfiniBand stack does not support flow steering at the verbs level -- the only usage of flow steering in the IB driver is for L2 multicast attaches. We need to add the IB case to procedure mlx4_QP_FLOW_STEERING_ATTACH_wrapper() to allow IPoIB to work on VFs on ConnectX-3 when flow steering is enabled. Currently, the IB case in mlx4_QP_FLOW_STEERING_ATTACH_wrapper() is missing, so the procedure returns -EINVAL and IPoIB on VFs breaks.

git://git.infradead.org/users/dhowells/linux-headers Pull preparatory patches for user API disintegration from David Howells: "The patches herein prepare for the extraction of the Userspace API bits from the various header files named in the Kbuild files. New subdirectories are created under either include/uapi/ or arch/x/include/uapi/ that correspond to the subdirectory containing that file under include/ or arch/x/include/. The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build.

2012-10-03bnx2x: fix ring size for 10G functionsYuval Mintz
Commit d760fc37b0f74502b3f748951f22c6683b079a8e caused 1G functions to allocate rx rings which were 1/10 of the size of 10G functions' rx rings. However, it also caused 10G functions on 5771x boards to allocate small rings, which limits their possible (default) rx throughput. This patch causes all 10G functions to use rings of intended length by default.

2012-10-03asm-generic: xor: mark static functions as __maybe_unusedArnd Bergmann
The asm-generic/xor.h header file is nasty and defines static functions that are not inline. The header file is include by the ARM version of asm/xor.h, which uses some but not all of the symbols defined there. Marking the extraneous functions as __maybe_unused lets gcc drop them without complaining. Without this patch, building iop13xx_defconfig results in: include/asm-generic/xor.h:696:34: warning: 'xor_block_8regs_p' defined but not used [-Wunused-variable] include/asm-generic/xor.h:704:34: warning: 'xor_block_32regs_p' defined but not used [-Wunused-variable] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Dan Williams <dan.j.williams@gmail.com> Cc: Neil Brown <neilb@suse.de>

2012-10-03ceph: avoid 32-bit page index overflowAlex Elder
A pgoff_t is defined (by default) to have type (unsigned long). On architectures such as i686 that's a 32-bit type. The ceph address space code was attempting to produce 64 bit offsets by shifting a page's index by PAGE_CACHE_SHIFT, but the result was not what was desired because the shift occurred before the result got promoted to 64 bits. Fix this by converting all uses of page->index used in this way to use the page_offset() macro, which ensures the 64-bit result has the intended value.
