bfcdefd8aa
PCB in which the context of stopped CPUs is stored. To access this PCB from KDB, we introduce a new define, called KDB_STOPPEDPCB. The definition, when present, lives in <machine/kdb.h> and abstracts where MD code saves the context. Define KDB_STOPPEDPCB on i386, amd64, alpha and sparc64 in accordance to previous code.
