* [libata] pata_pcmcia: Add additional id string (corsair, 1GB)Kristoffer Ericson2007-10-15

* libata: prevent devices with blank model names from being DMA blacklistedAndrew Paprocki2007-10-15
| | | | | | | | | | | | The strn_pattern_cmp routine does not handle a blank name parameter properly. The only patterns which should match a blank name are "*" and an explicit "". If the function is passed a blank name in current code, it will always match against the patt parameter. The bug manifests itself as the device with the empty model name always matching the first device in the DMA blacklist, forcing it to revert to PIO mode.

* ata_piix: SATA 2port controller port map fixJason Gaston2007-10-15
| | | | | | | This patch adds a port map for ICH9 and ICH8 SATA controllers that have only 2 ports available in that mode. Signed-off-by: Jason Gaston <jason.d.gaston@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* pata_cs5536: ATA driver for Geode companion chipMartin K. Petersen2007-10-15
| | | | | | | | | | | | | This is a driver for the ATA controller on the Geode CS5536 companion chip. The PCI device ID for this device was previously claimed by pata_amd.c but the PIO timings were not correct. This driver also works around a bug in some BIOSes that handle unaligned access to the PCI config registers poorly. Finally, the driver allows fallback to using MSR registers for configuration on BIOSes that are truly broken. Signed-off-by: Martin K.

* libata: fix revalidation issuing after configuration commandsTejun Heo2007-10-15
| | | | | | | | | | | | | | After commands which can change device configuration, EH is scheduled to revalidate and reconfigure the device. Host link was incorrectly used unconditionally when scheduling EH action. This resulted in bogus revalidation request and mismatched configuration between device and driver. Fix it. This bug was reported by Igor Durdanovic. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Igor Durdanovic <idurdanovic@comcast.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [libata] sata_nv: add SW NCQ support for MCP51/MCP55/MCP61Kuan Luo2007-10-15
| | | | | | | | | | | | | | Add the Software NCQ support to sata_nv.c for MCP51/MCP55/MCP61 SATA controller. NCQ function is disable by default, you can enable it with 'swncq=1'. NCQ will be turned off if the drive is Maxtor on MCP51 or MCP55 rev 0xa2 platform.

* [libata] pata_sil680: Add MMIO supportBenjamin Herrenschmidt2007-10-15
| | | | | | | | | | | | | | This patch adds MMIO support to the pata_sil680 for taskfile IOs, based on what the old siimage does. I haven't bothered changing the chip setup stuff from PCI config cycles to MMIO though (siimage does it), I don't think it matters, I've only adapted it to use MMIO for taskfile accesses. I've tested it on a Cell blade and it seems to work fine. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | We're failing basic test6 against Linux servers because they lack a correct change attribute. The fix is to assume that we always want to invalidate the readdir caches when we call update_changeattr and/or nfs_post_op_update_inode on a directory.

| * SUNRPC: Fix default hostname created in rpc_create()J. Bruce Fields2007-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 43780b87fa7..., rpc_create() fills in a default hostname based on the ip address if the servername passed in is null. A small typo made that default incorrect. (But this information appears to be used only for debugging right now, so I don't believe the typo causes any bugs in the current kernel.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the client, when an alternate server port is specified on the mount commandline, we need to make sure gssd knows about it. Also, on the server side, when we're sending krb5 callbacks to the client, we'll use the same mechanism to let gssd know about the callback port.
