The current driver never does DMA unmapping on these buffers. Fix that by adding DMA unmapping to the task cleanup callback, and DMA mapping to the task init function (drop the headers_initialized micro-optimization). Signed-off-by:

The driver counted on the transactional nature of iSCSI login/text flows and used the same buffer for both the request and the response. We also went further and did DMA mapping only once, with DMA_FROM_DEVICE, which violates the DMA mapping API. Fix that by using different buffers, one for requests and one for responses, and use the correct DMA mapping direction for each. Signed-off-by:

In sysfs_rename we need to remove the optimization of not calling sysfs_unlink_sibling and sysfs_link_sibling if the renamed parent directory is not changing. This optimization is no longer valid now that sysfs dirents are stored in an rbtree sorted by name. Move the assignment of s_ns before the call of sysfs_link_sibling. With no sysfs_dirent fields changing after the call of sysfs_link_sibling this allows sysfs_link_sibling to take any of the directory entries into account when it builds the rbtrees, and s_ns looks like a prime canidate to be used in the rbtree in the future.

This is the fifth version of the patchset (with one tiny whitespace fix) to the Linux kernel to support the Qualcomm Hexagon architecture. Between now and the next pull requests, Richard Kuo should have his key signed, etc., and should be back on kernel.org. In the meantime, this got merged as a emailed patch-series. * Hexagon: (36 commits) Add extra arch overrides to asm-generic/checksum.h Hexagon: Add self to MAINTAINERS Hexagon: Add basic stacktrace functionality for Hexagon architecture. Hexagon: Add configuration and makefiles for the Hexagon architecture. Hexagon: Comet platform support Hexagon: kgdb support files Hexagon: Add page-fault support. Hexagon: Add page table header files & etc. Hexagon: Add ioremap support Hexagon: Provide DMA implementation Hexagon: Implement basic TLB management routines for Hexagon. Hexagon: Implement basic cache-flush support Hexagon: Provide basic implementation and/or stubs for I/O routines. Hexagon: Add user access functions Hexagon: Add locking types and functions Hexagon: Add SMP support Hexagon: Provide basic debugging and system trap support. Hexagon: Add ptrace support Hexagon: Add time and timer functions Hexagon: Add interrupts ...

There are plausible reasons for architectures to provide their own versions of csum_partial_copy_nocheck and csum_tcpudp_magic. By protecting these, the architecture can still re-use the asm-generic checksum.h, instead of copying it. Signed-off-by:
