business models [was patent stuff]

Of course you *can*, but do you (or anyone else) actually does this? AFAIK this is not a very common business model.

Hi volks!

I get this error when trying to compile kernel 2.5.18 on alpha.

Please help me!

Is there really nobody who can help me with this error?

If you're not capable of reading the list archives, and picking up the patches which I believe I recall seeing, then no - I suspect you are indeed beyond help.

Just intended to post the patch... :-)

- sync up with new pte/pfn/page/tlb macros
- pcibios_init() should return int;
- find last bit set: ctlz for ev67 and above, generic for others.

I'm not sure what to do with this. I doubt that we ever want this file on alpha. For myself I moved "#include <asm/suspend.h>" under #ifdef CONFIG_SOFTWARE_SUSPEND and everything compiles.

Ivan.

Yes. It does! Great job! But there are new problems with 2.5.20. I try to catch 'em. I may find the gizmo... :o)
