Subject: [PATCH 6/8] isaectomy: hp100
Date: Wed, 16 Nov 2005 03:50:47 +0000	[thread overview]
Message-ID: <E1EcEJr-0007eA-98@ZenIV.linux.org.uk> (raw)

From: Al Viro <viro@zeniv.linux.org.uk>
Date: 1132110592 -0500

hp100 has ->mem_ptr_virt set for all memory-mapped cases; removed
rudiment of old version that used ioremap() only when physical
address wasn't an ISA one.  These days it's simply a dead code.
