mips: use the the PCI controller's io_map_base

2012-01-31T21:20:30+00:00

commit eab90291d35438bcebf7c3dc85be66d0f24e3002
(mips: switch to GENERIC_PCI_IOMAP)
failed to take into account the PCI controller's
io_map_base for mapping IO BARs.
This also caused a new warning on mips.

Fix this, without re-introducing code duplication,
by setting NO_GENERIC_PCI_IOPORT_MAP
and supplying a mips-specific __pci_ioport_map.

mips: switch to GENERIC_PCI_IOMAP

2011-11-28T19:13:13+00:00

mips copied pci_iomap from generic code, probably to avoid
pulling the rest of iomap.c in.  Since that's in
a separate file now, we can reuse the common implementation.

MIPS: Separate two consecutive loads in memset.S

2010-12-16T18:10:57+00:00

partial_fixup is used in noreorder block.

Separating two consecutive loads can save one cycle on processors with
GPR intrelock and can fix load-use on processors that need a load delay slot.

Also do so for fwd_fixup.

[Ralf: Only R2000/R3000 class processors are lacking the the load-user
interlock and even some of those got it retrofitted.  With R2000/R3000
being fairly uncommon these days the impact of this bug should be minor.]
