The patch titled
e100: Fix bogus PCI quirk
has been removed from the -mm tree. Its filename was
e100-fix-bogus-pci-quirk.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: e100: Fix bogus PCI quirk
From: Benjamin Herrenschmidt <[EMAIL PROTECTED]>
Linas reported that some machines were crashing at boot in
quirk_e100_interrupt. It appears that this quirk is doing an ioremap
directly on a PCI BAR value, which isn't legal and will cause all sorts of
bad things to happen on architectures where PCI BARs don't directly match
processor bus addresses.
This fixes it by using the proper PCI resources instead which is possible
since the quirk has been moved by a previous commit to happen late enough
for that.
