        sys/arch/x86/include/lock.h: revision 1.26
Change "=r" to "=qQ" in a register constraint in an asm statement
for a register that is used with the "xchgb" instruction in the
definition of __cpu_simple_lock_try().  This fixes PR 45673, or at
least works around the gcc bug that might be behind PR 45673.
The output from "objdump -d" before and after this change is
identical, for the amd64 GENERIC kernel, the i386 GENERIC kernel,
and the i386 MONOLITHIC kernel.
