MIPS: Get rid of 'kgdb_early_setup' cruft.

2015-06-21T19:54:10+00:00

Commit 854700115ecf ([MIPS] kgdb: add arch support for the kernel's kgdb core) added the 'kgdb_early_setup' flag to avoid calling trap_init() and init_IRQ() the second time, however the code that called these functions earlier, from kgdb_arch_init(), had been already removed by that time, so the flag never served any useful purpose. Remove the related code along with ugly #ifdef'ery at last.

mips,kgdb: kdb low level trap catch and stack trace

2010-05-21T02:04:26+00:00

The only way the debugger can handle a trap in inside rcu_lock, notify_die, or atomic_notifier_call_chain without a recursive fault is to have a low level "first opportunity handler" do_trap_or_bp() handler. Generally this will be something the vast majority of folks will not need, but for those who need it, it is added as a kernel .config option called KGDB_LOW_LEVEL_TRAP. Also added was a die notification for oops such that kdb can catch an oops for analysis. There appeared to be no obvious way to pass the struct pt_regs from the original exception back to the stack back tracer, so a special case was added to show_stack() for when kdb is active because you generally desire to generally look at the back trace of the original exception.
