[PATCH] ide-scsi: kmap scatter/gather before doing PIO
From: Stuart Hayes <Stuart_Hayes@dell.com>
The system can panic with a null pointer dereference using ide-scsi if
PIO is being done on scatter gather pages that are in high memory,
because page_address() returns 0. We are actually seeing this using a
tape drive. This patch will kmap_atomic() the pages before performing
PIO.
