2006-03-20[libata] sata_mv: fix irq port status usageJeff Garzik
Interrupt handler did not properly initialize a variable on a per-port basis, leading to incorrect behavior on ports other than port 0. Bug caught and fixed by Mark Lord. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-03-19[TG3]: 40-bit DMA workaround part 2Michael Chan
The 40-bit DMA workaround recently implemented for 5714, 5715, and 5780 needs to be expanded because there may be other tg3 devices behind the EPB Express to PCIX bridge in the 5780 class device. For example, some 4-port card or mother board designs have 5704 behind the 5714. All devices behind the EPB require the 40-bit DMA workaround. Thanks to Chris Elmquist again for reporting the problem and testing the patch. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-18[PATCH] Kconfig: swap VIDEO_CX88_ALSA and VIDEO_CX88_DVBMichael Krufky
VIDEO_CX88_ALSA should not be between VIDEO_CX88_DVB and VIDEO_CX88_DVB_ALL_FRONTENDS When cx88-alsa was added to cx88/Kconfig, it was added in between VIDEO_CX88_DVB and VIDEO_CX88_DVB_ALL_FRONTENDS. This caused undesireable effects to the appearance of the menu options in menuconfig. This fix reorders cx88-alsa and cx88-dvb in Kconfig, to match saa7134, and restore the correct menuconfig appearance.

2006-03-17[PATCH] dm stripe: Fix boundsKevin Corry
The dm-stripe target currently does not enforce that the size of a stripe device be a multiple of the chunk-size. Under certain conditions, this can lead to I/O requests going off the end of an underlying device. This test-case shows one example. echo "0 100 linear /dev/hdb1 0" | dmsetup create linear0 echo "0 100 linear /dev/hdb1 100" | dmsetup create linear1 echo "0 200 striped 2 32 /dev/mapper/linear0 0 /dev/mapper/linear1 0" | \ dmsetup create stripe0 dd if=/dev/zero of=/dev/mapper/stripe0 bs=1k This will produce the output: dd: writing '/dev/mapper/stripe0': Input/output error 97+0 records in 96+0 records out And in the kernel log will be: attempt to access beyond end of device dm-0: rw=0, want=104, limit=100 The patch will check that the table size is a multiple of the stripe chunk-size when the table is created, which will prevent the above striped device from being created. This should not affect tools like LVM or EVMS, since in all the cases I can think of, striped devices are always created with the sizes being a multiple of the chunk-size. The size of a stripe device must be a multiple of its chunk-size.

- Disable the EDAC sysfs code. The sysfs interface that EDAC presents to user space needs more thought, and is likely to change substantially.

2006-03-11[PATCH] sata_sil24: exit early from softreset if SStatus reports no deviceTejun Heo
sata_sil24 softreset routine used to check sata_dev_present() after SRST is complete in the hope that SRST may do some good even when SStatus reports no device. This is okay as long as SRST timeout is short (> 100ms in the current code) but it seems that not all SATA devices are happy with short SRST timeout. This patch makes softreset exit early without performing actual SRST if SStatus reports no device in preparation for lengthening SRST timeout.
