	*  1. This patch allows KDB to work with any Host Contoller driver

	* Move to finer grained control over individual processors in kdb with
	per cpu kdb state.  Needed to allow ss[b] to only release one processor,
	previously ss[b] released all processors.  Also need to recover from
	errors inside kdb commands, e.g. oops in kdbm_pg code.

	* various:
	  Move global flags KDB_FLAG_SSB, KDB_FLAG_SUPRESS, KDB_FLAG_FAULT,
	  KDB_FLAG_SS, KDB_FLAG_SSBPT, kdb_active, to per cpu state and macros
	  KDB_STATE(xxx).
	  Replace kdb_flags & KDB_FLAG_xxx with KDB_FLAG(xxx).
	  Replace kdb_flags & KDB_DEBUG_xxx with KDB_DEBUG(xxx).
	  Replace specific tests with wrapper KDB_IS_RUNNING().

	command.  More detailed return codes for commands that affect
	processors.

	kdb handles them.  ss[b] now releases only the current cpu.  Do not set
	breakpoints when releasing for ss[b].  Recover from errors in kdb
	commands.  Check that we have reliable longjmp data before using it.

	* various: Update return code documentation.

	* kdb/kdb_bp.c (kdb_ss): Separate ss and ssb return codes.

	codes.  Reinstall delayed software breakpoints per cpu instead of
	globally.  Changed algorithm for handling ss[b].

	* arch/i386/kdb/kdba_bp.c (kdba_bp_trap): Match software breakpoints per
	cpu instead of globally.
