2010-05-25spi/pl022: fix stop queue procedureGrzegorz Sygieda
This fix prevents queue being marked as "stopped", if data exists in the queue list.

2010-05-25spi/pl022: add support for the PL023 derivateLinus Walleij
This adds support for a further ST variant of the PL022 called PL023. Some differences in the control registers due to being stripped down to SPI mode only, and a new clock feedback sample delay config setting is available.

2010-05-25spi/pl022: fix up differences between ARM and ST versionsLinus Walleij
The PL022 SPI driver did not cleanly separate between the original unmodified ARM version and the ST Microelectronics versions. Split this more cleanly and fix some whitespace moaning from checkpatch at the same time.

2010-05-25spi/spi_mpc8xxx: Do not use map_tx_dma to unmap rx_dmaJoakim Tjernlund
This fixes a typo were map_tx_dma is used instead of map_rx_dma, casing the driver to unmap rx_dma when it shouldn't. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Acked-by: Anton Vorontsov <cbouatmailru@gmail.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-05-25spi/spi_mpc8xxx: Fix QE mode Litte EndianJoakim Tjernlund
QE mode uses Little Endian so words > 8 bits are byte swapped. Workaround this by always enforcing wordsize 8 for words > 8 bits. Unfortunately this will not work for LSB transfers where wordsize is > 8 bits so disable these for now. Also move the different quirks into its own function to keep mpc8xxx_spi_setup_transfer() sane.

2010-05-24RDMA/nes: Async event for closed QP causes crashFaisal Latif
Under abnormal termination, modify_qp() closes the QP, and async event (AE) handling also attempts to close the same QP, causing a crash.

The functionality to keep the device awake until it is done with the rx of any mcast/bcast frames which are pending on AP should also be added to the hardwares which support auto sleep feature.

2010-05-24ath5k: consistently use rx_bufsize for RX DMABruno Randolf
We should use the same buffer size we set up for DMA also in the hardware descriptor. Previously we used common->rx_bufsize for setting up the DMA mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the descriptor itself. The problem is that skb_tailroom(skb) can give us a larger value than the size we set up for DMA before. This allows the hardware to write into memory locations not set up for DMA. In practice this should rarely happen because all packets should be smaller than the maximum 802.11 packet size. On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559 bytes length (including padding for cache alignment) but sbk_tailroom() was 2592. Just consistently use rx_bufsize for all RX DMA memory sizes. Also use the return value of the descriptor setup function.
