Subject: [MIPS] PCI: Port i386 PCI fixes.
X-Git-Tag: v2.6.25-rc3~110^2~5
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=986c94854e5615000f39edfc788dffff7035ec7d;p=linux-2.6

[MIPS] PCI: Port i386 PCI fixes.

The MIPS version of pcibios_enalbe_resources did not have the fixes
from ed6d14f9760857c745206c978b80352fc09cfd19 yet which under circumstances
similar to x86 might result in failures.
