[Xen-devel] Add a semaphore in ring0

[Carlo Maiero <zesster@xxxxxxxxx>]

How can I use a semaphore in a function that I use in /xen/arch/x86/traps.c , xen version 4.0.1

I implement the function in the same level /xen/arch/x86/ and so used in ring0.

i've to add a semaphore for a producer-consumer system.

and a semaphore (or a wait) for a condition.
