[PATCH 6/8] isaectomy: hp100

[Al Viro <viro@ftp.linux.org.uk>]

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.
