Thanks, I'll wordsmith the description a bit. There's actually nothing
in the implementation that prevents this from working on non-HP firmware.
I really want feedback on the best approach of:
1. Always build the driver static, accept the additional 4600 bytes
in everybody's image, not export anything.
2. Allow building driver as a module, export sal_lock. This would
also enable building arch/ia64/kernel/esi.c as a module.
3. Allow building driver as a module, restructure SAL_CALL so we
don't have to export sal_lock, but we do export fw_call_lock()
(as done in these patches). This isn't quite sufficient to
enable building esi.c as a module.
#1 would be easiest, of course, but I'm not happy about adding stuff
that is only used on HP hardware. #2 would be simple, but exporting
sal_lock has been resisted in the past.
