Subject: scsi: make ppa depend on !HIGHMEM
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=79a835ec6d08ee05c97f9e58501ce4ce7a442e37;p=users%2Fhch%2Fmisc.git

scsi: make ppa depend on !HIGHMEM

This is one of the last drivers depending on the block layer bounce
buffering code.  Restrict it to run on non-highmem configs so that the
bounce buffering code can be removed.
