---------------------------
-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

- /* These are here in an effort to more fully work around
- * Spitfire Errata #51. Essentially, if a memory barrier
- * occurs soon after a mispredicted branch, the chip can stop
- * executing instructions until a trap occurs. Therefore, if
- * interrupts are disabled, the chip can hang forever.
- *
- * It used to be believed that the memory barrier had to be
- * right in the delay slot, but a case has been traced
- * recently wherein the memory barrier was one instruction
- * after the branch delay slot and the chip still hung. The
- * offending sequence was the following in sym_wakeup_done()
- * of the sym53c8xx_2 driver:
- *
- * call sym_ccb_from_dsa, 0
- * movge %icc, 0, %l0
- * brz,pn %o0, .LL1303
- * mov %o0, %l2
- * membar #LoadLoad
- *
- * The branch has to be mispredicted for the bug to occur.
- * Therefore, we put the memory barrier explicitly into a
- * "branch always, predicted taken" delay slot to avoid the
- * problem case.

-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.
