Only alpha, ia64, powerpc, and sh define SLOW_DOWN_IO, and there are no
actual uses of it.  The few references to it are in situations that are
themselves unused.  Remove them all.

It should be safe to apply these independently and in any order.  The only
place SLOW_DOWN_IO is used at all is the lmc_var.h definition of DELAY,
which is itself never used.

Bjorn Helgaas (7):
  net: wan: atp: remove unused eeprom_delay()
  net: wan: lmc: remove unused DELAY()
  net: remove comments that mention obsolete __SLOW_DOWN_IO
  sh: remove unused SLOW_DOWN_IO
  powerpc: Remove unused SLOW_DOWN_IO definition
  ia64: remove unused __SLOW_DOWN_IO and SLOW_DOWN_IO definitions
  alpha: remove unused __SLOW_DOWN_IO and SLOW_DOWN_IO definitions

Hi Bojrn! Would you mind reposting just patches 1 and 3 for networking?
LMC got removed in net-next (commit a5b116a0fa90 ("net: wan: remove the
lanmedia (lmc) driver")) so the entire series fails to apply and therefore 
defeats all of our patch handling scripts :S
