From 1e8a8cc52daa95e702303ca3ce67955a4c051d7d Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 28 Feb 2007 23:38:38 -0800 Subject: [PATCH] [SPARC64]: Internalize pci_memspace_mask. The only user was bus_dvma_to_mem() which is no longer used by any driver, so kill that, and the export of pci_memspace_mask. The only user now is the PCI mmap support code. Signed-off-by: David S.
