X-Git-Tag: v2.6.15-rc1~18^2~42

[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 17fd47ab4d33e764216b87006d8118fa050b4c92
