Subject: [PATCH] Sort generic PCI fixups after specific ones
Date: Wed, 22 Sep 2004 22:43:04 +0100	[thread overview]
Message-ID: <20040922214304.GS16153@parcelfarce.linux.theplanet.co.uk> (raw)


The recent change that allowed PCI fixups to be declared everywhere
broke IDE on PA-RISC by making the generic IDE fixup be applied before
the PA-RISC specific one.  This patch fixes that by sorting generic fixups
after the specific ones.  It also obeys the 80-column limit and reduces
the amount of grotty macro code.

I'd like to thank Joel Soete for his work tracking down the source of
this problem.

"Next the statesmen will invent cheap lies, putting the blame upon 
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain
