SubjectRE: PCI-PCI bridges mess in 2.4.x
Hi Jeff-

> Also, should we be setting PCI_CACHE_LINE_SIZE for PCI devices as well
> as bridges?

If/when we do set PCI_CACHE_LINE_SIZE, please don't
set it to a hard-coded, inline constant, like 8 (e.g.),
like some drivers do.

Please use something like (PCI_CACHE_LINE_SIZE / 4)
instead. ["/ 4" to convert bytes to "dwords" or
whatever, since the PCI_CACHE_LINE_SIZE register
is in 4-byte units.]
