2009-03-05ide: add at91_ide driverStanislaw Gruszka
This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory Controller with Compact Flash True IDE Mode logic. Driver have to switch 8/16 bit bus width when accessing Task Tile or Data Register. Moreover some extra things need to be done when setting PIO mode. Only PIO mode is used, hardware have no DMA support. If interrupt line is connected through GPIO extra quirk is needed to cope with fake interrupts.

2009-03-05libata: Don't trust current capacity values in identify words 57-58Robert Hancock
Hanno Böck reported a problem where an old Conner CP30254 240MB hard drive was reported as 1.1TB in capacity by libata: http://lkml.org/lkml/2009/2/13/134 This was caused by libata trusting the drive's reported current capacity in sectors in identify words 57 and 58 if the drive does not support LBA and the current CHS translation values appear valid. Unfortunately it seems older ATA specs were vague about what this field should contain and a number of drives used values with wrong byte order or that were totally bogus. There's no unique information that it conveys and so we can just calculate the number of sectors from the reported current CHS values. While we're at it, clean up this function to use named constants for the identify word values. Signed-off-by: Robert Hancock <hancockrwd@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-03-05libata: make sure port is thawed when skipping resetsTejun Heo
When SCR access is available and the link is offline, softreset is skipped as it only wastes time and some controllers don't respond very well. However, the skip path forgot to thaw the port, which not only blocks further event notification from the port but also causes repeated EH invocations on the same event on drivers which rely on ->thaw() to clear events if the IRQ is shared with another device or port. This problem has always been there but is uncovered by recent sata_nv nf2/3 change which dropped hardreset support while maintaining SCR access. nf2/3 doesn't clear hotplug event mask from the interrupt handler but relies on ->thaw() to clear them. When the hardreset was there, the reset action was never skipped and the port was always thawed but, with the hardreset gone, ->prereset() determines that there's no need for softreset and both ->softreset() and ->thaw() are skipped. This leads to stuck hotplug event in the IRQ status register triggering hotplug event whenever IRQ is delieverd on the same IRQ. As the controller shares the same IRQ for both ports, this happens on every IO if one port is occpupied and the other isn't. This patch fixes the problem by making sure that the port is thawed on reset-skip path. bko#11615 reports this problem.

2009-03-05libata: change drive ready wait after hard reset to 5sStuart Hayes
This fixes problems during resume with drives that take longer than 1s to be ready. The ATA-6 spec appears to allow 5 seconds for a drive to be ready. On one affected system, this patch changes "PM: resume devices took..." message from 17 seconds to 4 seconds, and gets rid of a lot of ugly timeout/error messages. Without this patch, the libata code moves on after 1s, tries to send a soft reset (which the drive doesn't see because it isn't ready) which also times out, then an IDENTIFY command is sent to the drive which times out, and finally the error handler will try to send another hard reset which will finally get things working.

IMHO the setting should depend on ANOMALY_05000305 which is about the availability of the bit, not ANOMALY_05000265 which only describes the SPORT sensitivity to noise (checked for BF561 only, though).

2009-03-04ext4: fix ext4_free_inode() vs. ext4_claim_inode() raceEric Sandeen
I was seeing fsck errors on inode bitmaps after a 4 thread dbench run on a 4 cpu machine: Inode bitmap differences: -50736 -(50752--50753) etc... I believe that this is because ext4_free_inode() uses atomic bitops, and although ext4_new_inode() *used* to also use atomic bitops for synchronization, commit 393418676a7602e1d7d3f6e560159c65c8cbd50e changed this to use the sb_bgl_lock, so that we could also synchronize against read_inode_bitmap and initialization of uninit inode tables. However, that change left ext4_free_inode using atomic bitops, which I think leaves no synchronization between setting & unsetting bits in the inode table. The below patch fixes it for me, although I wonder if we're getting at all heavy-handed with this spinlock...
