[PATCH] revert ide-scsi highmem cleanup
Jeff Garzik <jgarzik@pobox.com> points out that this was wrong: we need to disable local interrupts while holding KM_IRQ0 due to IRQ sharing. And holding interrupts off during a big PIO opration is expensive, so we only want to do that if we know the page was highmem. So revert commit 17fd47ab Signed-off-by:Andrew Morton <akpm@osdl.org> Signed-off-by:
