CVS commit: [newlock] syssrc/sys/arch/i386/i386

[Jason R Thorpe <thorpej%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   thorpej
Date:           Mon Mar 18 01:05:12 UTC 2002

Modified Files:
        syssrc/sys/arch/i386/i386 [newlock]: lock_stubs.s

Log Message:
Add support for the CPUCLASS_386 processors, which lack the
CMPXCHG insn.  We support these processors by blocking interrupts
during the critical sections of the locking primitives.  This will
obviously have to change if we ever support multiprocessor 386
systems (like, say, the old Sequent Symmetry systems).
