From: Randy Dunlap Add help info for BLK_DEV_SD referring to its use in SATA or PATA driver configurations. Add help text for "ATA" indicating that it probably needs some SCSI config symbols enabled in order to be useful.

It seems sometimes the mdelay() function is not as precise as it used to be. Per Alan's advice, HT or power management might affect the precision of mdelay(). This patch calls gettimeofday() to mesure the time elapsed and calculate the PLL input clock accordingly.

This patch was originally submitted by Jeff Garzik. Added PCI-ID 1180 for SiS966 Controller in pata_sis. The 1180 mode is fully compatible to other SiS PATA-controller. The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis. 1183 is not working if simply added to pata_sis.
