Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 2005-04-17 02:20:36 +04:00			`#ifndef _AHA152X_H`

[SCSI] aha152x: fix variable use before initialisation and other bugs - change interface of the reset functions from Scsi_Cmnd to Scsi_Host. - add functions with the original interface and rename the new functions to reflect the new interface. - call these from the pcmcia driver, thereby avoiding the need to construct a (broken) Scsi_Cmnd from a Scsi_Host. - just run the bh if the interrupt is from the controller and if so ensure that it's only called once per interrupt.
