Re: 2.2.2pre5 followup (semaphores)

[Robert Bowles <rbowles op net>]

Thanks for the answer:

'linux/include/asm-i386/semaphore.h' has an
asmlinkage int  __down_trylock(struct semaphore * sem);

Whereas 'linux/include/asm-alpha/semaphore.h' has none.
I'm just adding "the line" and building right now. :)
