Re: [2.6 patch] SCSI aic7xxx: kill kernel 2.2 #ifdef's
From: maximilian attems
Date: Sat Oct 23 2004 - 13:16:36 EST
the kjt patchset has an similar patch, that got sent to James:
the bits below were a leftover of a janitor patch removing
aic7xxx and aic79xx old ifdefs.

kernel janitor http://janitor.kernelnewbies.org/
From: Domen Puncer <domen@xxxxxxxxxxxx>
Patches to remove some old ifdefs.
remove most of the #include <linux/version.h>
kill compat cruft like #define ahd_pci_set_dma_mask pci_set_dma_mask
