Changeset 9928240 in mainline for kernel/arch/ia64/src/mm/tlb.c

Message:

Use exc_dispatcher() for ia64 interruptions.

This is necessary for proper cycle accounting and also CPU state
tracking (idle / non-idle). Syscalls continue to use a different
path, but call syscall_handler() eventually. The speculation
vector needs to be handled differently, outside of exc_dispatch().
