jhb 2463f40fc3 Introduce a standard name for the lock protecting an interrupt controller ... and it's associated state variables: icu_lock with the name "icu". This renames the imen_mtx for x86 SMP, but also uses the lock to protect access to the 8259 PIC on x86 UP. This also adds an appropriate lock to the various Alpha chipsets which fixes problems with Alpha SMP machines dropping interrupts with an SMP kernel.		2001-12-20 23:48:31 +00:00
