Subject[PATCH v2 0/4] sparc64: Jump to boot prom from console on panic
Date
Currently Stop-A (L1A) does not make the kernel switch to OBP on panic. This
patchset addresses this issue. Also, now we can cause a jump to OBP by sending
'break' twice from sunhv console. On bare metal, one can send a break by
typing Esc + 'B' + Sysrq (or whatever). On LDOM, press Ctrl + ] in telnet,
and then "send break" at the telnet prompt.

sparc64: Set cpu state to offline when stopped
sparc64: Migrate hvcons irq to panicked cpu
sparc64: Send break twice from console to return to boot prom
