Modified files:
sys/i386/include cpufunc.h param.h profile.h smp.h
smptests.h
sys/i386/isa apic_vector.s clock.c cy.c intr_machdep.c
sio.c
sys/i386/i386 exception.s mp_machdep.c mplock.s
Added files:
sys/i386/include lock.h
Log:
Another round of lock pushdown.
Add a simplelock to deal with disable_intr()/enable_intr() as used in UP kernel.
UP kernel expects that this is enough to guarantee exclusive access to
regions of code bracketed by these 2 functions.
Add a simplelock to bracket clock accesses in clock.c: clock_lock.
