Subject: [PATCH] Fix restore of 64-bit PCI BAR's
X-Git-Tag: v2.6.13-rc6~16
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cf7bee5a0bf270a4eace0be39329d6ac0136cc47;p=pandora-kernel.git

[PATCH] Fix restore of 64-bit PCI BAR's

For 64-bit BAR[i] only pci_dev->resource[i] is valid, ->resource[i+1]
slot is unused and contains zeroes in all fields.

So when we update a PCI BAR, all we need is just to check that we're
going to update a _valid_ resource.

Also make sure to write high bits - use "x >> 16 >> 16" (rather than the
simpler ">> 32") to avoid warnings on 32-bit architectures where we're
not going to have any high bits.
