2012-12-21ide: Increase WAIT_DRQ to accomodate some CF cards and SSD drives.David S. Miller
Based upon a patch by Philippe De Muyter, and feedback from Mark Lord and Robert Hancock. As noted by Mark Lord, the outdated ATA1 spec specifies a 20msec timeout for setting DRQ but lots of common devices overshoot this. Signed-off-by: David S. Miller <davem@davemloft.net> (cherry picked from Linux kernel commit 602da297e293eb2cbd28dcdbbe247593a46a853a) * linux/src/drivers/block/ide.h (WAIT_DRQ): Increase to 1 s.

2012-11-19Fix compilation error with older versions of GCCMatthew Leach
Some versions of GCC will error if you define a type twice (even if the definition is the same). The NCR53C8XX SCSI driver defines 'vm_offset_t', this is also defined in vm_types.h and will therefore cause a compilation error depending on the GCC version. * linux/src/drivers/scsi/ncr53c8xx.c [!MACH] (vm_offset_t, vm_size_t): Don't define types.
