@ -25,15 +25,6 @@ Who: Pavel Machek <pavel@suse.cz>
---------------------------
What: PCI Name Database (CONFIG_PCI_NAMES)
When: July 2005
Why: It bloats the kernel unnecessarily, and is handled by userspace better
(pciutils supports it.) Will eliminate the need to try to keep the
pci.ids file in sync with the sf.net database all of the time.
Who: Greg Kroah-Hartman <gregkh@suse.de>
---------------------------
What: io_remap_page_range() (macro or function)
When: September 2005
Why: Replaced by io_remap_pfn_range() which allows more memory space

config PCI_NAMES
bool "PCI device name database"
depends on PCI
---help---
By default, the kernel contains a database of all known PCI device
names to make the information in /proc/pci, /proc/ioports and
similar files comprehensible to the user.
This database increases size of the kernel image by about 80KB. This
memory is freed after the system boots up if CONFIG_HOTPLUG is not set.
Anyway, if you are building an installation floppy or kernel for an
embedded system where kernel image size really matters, you can disable
this feature and you'll get device ID numbers instead of names.
When in doubt, say Y.
