Subject: [PATCH 00/13] Asynchronous raid6 acceleration (part 1 of 2)
This series constitutes the pieces of the raid6 acceleration work that are
aimed at the next merge window. It implements:
1/ An api for asynchronous raid6 parity generation and recovery routines
2/ Extensions to the dmaengine framework and dmatest
3/ RAID6 support for iop13xx
4/ Removal of the BUILD_BUG_ON in async_xor to support platforms with
sizeof(dma_addr_t) > sizeof(void *). This increases the stack
utilization in the asynchronous path.
This series is available via git at:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git raid6
...it is based on git://neil.brown.name/md md-scratch
Part 2, which needs more testing, is the conversion of md/raid6. It is
available at:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/md.git raid6-for-neil

Dan Williams (12):
dmatest: add pq support
dmatest: add dma interrupts and callbacks
dmatest: add xor test
dmaengine: allow dma support for async_tx to be toggled
iop-adma: P+Q self test
iop-adma: P+Q support for iop13xx adma engines
async_tx: add support for asynchronous RAID6 recovery operations
async_tx: add support for asynchronous GF multiplication
async_tx: add sum check flags
async_tx: kill needless module_{init|exit}
async_tx: provide __async_inline for HAS_DMA=n archs
md/raid6: move raid6 data processing to raid6_pq.ko
Yuri Tikhonov (1):
async_tx: don't use src_list argument of async_xor() for dma addresses
