2010-10-14hfsplus: fix oops on mount with corrupted btree extent recordsJeff Mahoney
A particular fsfuzzer run caused an hfs file system to crash on mount. This is due to a corrupted MDB extent record causing a miscalculation of HFSPLUS_I(inode)->first_blocks for the extent tree. If the extent records are zereod out, then it won't trigger the first_blocks special case and instead falls through to the extent code, which we're in the middle of initializing. This patch catches the 0 size extent records, reports the corruption, and fails the mount. [hch: ported of commit 47f365eb575735c6b2edf5d08e0d16d26a9c23bd from hfs] Reported-by: Ramon de Carvalho Valle <rcvalle@linux.vnet.ibm.com> Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Christoph Hellwig <hch@tuxera.com>

2010-10-13ioat2: fix performance regressionDan Williams
Commit 0793448 "DMAENGINE: generic channel status v2" changed the interface for how dma channel progress is retrieved. It inadvertently exported an internal helper function ioat_tx_status() instead of ioat_dma_tx_status(). The latter polls the hardware to get the latest completion state, while the helper just evaluates the current state without touching hardware. The effect is that we end up waiting for completion timeouts or descriptor allocation errors before the completion state is updated. iperf (before fix): [SUM] 0.0-41.3 sec 364 MBytes 73.9 Mbits/sec iperf (after fix): [SUM] 0.0- 4.5 sec 499 MBytes 940 Mbits/sec This is a regression starting with 2.6.35.

2010-10-13net: allow FEC driver to use fixed PHY supportGreg Ungerer
At least one board using the FEC driver does not have a conventional PHY attached to it, it is directly connected to a somewhat simple ethernet switch (the board is the SnapGear/LITE, and the attached 4-port ethernet switch is a RealTek RTL8305). This switch does not present the usual register interface of a PHY, it presents nothing. So a PHY scan will find nothing - it finds ID's of 0 for each PHY on the attached MII bus. After the FEC driver was changed to use phylib for supporting PHYs it no longer works on this particular board/switch setup. Add code support to use a fixed phy if no PHY is found on the MII bus. This is based on the way the cpmac.c driver solved this same problem. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-10-12spi/fsl_spi: add eSPI controller supportMingkai Hu
Add eSPI controller support based on the library code spi_fsl_lib.c. The eSPI controller is newer controller 85xx/Pxxx devices supported. There're some differences comparing to the SPI controller: 1. Has different register map and different bit definition So leave the code operated the register to the driver code, not the common code. 2. Support 4 dedicated chip selects The software can't controll the chip selects directly, The SPCOM[CS] field is used to select which chip selects is used, and the SPCOM[TRANLEN] field is set to tell the controller how long the CS signal need to be asserted. So the driver doesn't need the chipselect related function when transfering data, just set corresponding register fields to controll the chipseclect. 3. Different Transmit/Receive FIFO access register behavior For SPI controller, the Tx/Rx FIFO access register can hold only one character regardless of the character length, but for eSPI controller, the register can hold 4 or 2 characters according to the character lengths. Access the Tx/Rx FIFO access register of the eSPI controller will shift out/in 4/2 characters one time. For SPI subsystem, the command and data are put into different transfers, so we need to combine all the transfers to one transfer in order to pass the transfer to eSPI controller. 4. The max transaction length limitation The max transaction length one time is limitted by the SPCOM[TRANSLEN] field which is 0xFFFF. When used mkfs.ext2 command to create ext2 filesystem on the flash, the read length will exceed the max value of the SPCOM[TRANSLEN] field.

This patch makes multiple cleanups to the new topcliff pch spi driver including, but not limited to, - removing superfluous brackets around variables - open coding functions that are only used once - removing unnecessary line breaks - removing unused functions - simplifying the interrupt enable/disable code - remove unnecessary (void *) casts. - remove b_mem_fail from pch_spi_set_tx to code it more cleanly - shorten dev_dbg() messages for conciseness and readability More cleanups are still needed in this driver. In particular, - the driver filename should be changed to spi_topcliff_pch.c - many of the dev_dbg() lines should be trimmed (particularly the ones on unconditional code paths). - I suspect that the locking model not correct. I'd like to know what drivers' critical regions are, and how they are protected. - get_resources and release_resources probably should be open coded in .probe and .release respectively.

2010-10-12ARM: 6440/1: ep93xx: DMA: fix channel_disableMika Westerberg
When channel_disable() is called, it disables per channel interrupts and waits until channels state becomes STATE_STALL, and then disables the channel. Now, if the DMA transfer is disabled while the channel is in STATE_NEXT we will not wait anything and disable the channel immediately. This seems to cause weird data corruption for example in audio transfers. Fix is to wait while we are in STATE_NEXT or STATE_ON and only then disable the channel.
