[L4alpha-cvscommit] CVS: L4Alpha/pal/21164 l4_pal.mar,1.13,1.14

[Daniel P. <dp...@us...>]

Update of /cvsroot/l4alpha/L4Alpha/pal/21164
In directory usw-pr-cvs1:/tmp/cvs-serv4834/pal/21164

Modified Files:
	l4_pal.mar 
Log Message:
Interrupt mask and unmask functionality

When you do a l4_ipc_receive on your registered interrupt, it will enable the interrupt pin to the cpu. When the kernel recieves this and passes it on to you, it will disable (mask) this interrupt and pass it on to you.
This prevents some race conditions that were occuring.

Breaks the Ruffian port.
