>Description:

I recently noticed that my kernel started to emit the following
message:

	pci_mem_find: void region

The cause seems to be the rev. 1.10.10.1 of src/sys/dev/pci/pci_map.c,
which was pulled up recently.

>How-To-Repeat:

dmesg

>Fix:

Pulling up the following three changes fixes this problem.
Note that you have to replace "syssrc" with "src" in the following
message.

From: Matthias Drochner <drochner@netbsd.org>

Module Name:    syssrc
Committed By:   drochner
Date:           Thu May 30 12:06:43 UTC 2002

Modified Files:
        syssrc/sys/dev/pci: pci_map.c pcivar.h vga_pci.c

Log Message:
implement a check whether a BAR is present at all at a given configuration
space address and use it where the mappings of the VGA card are registered
before descenting too deep into "memory" type specific code
(pci_mem_find() gets noisy if it doesn't like the register)
