o Rename global variable "tramp" to "vax_mp_tramp" to avoid warning
with -Wshadow when compiling the signal code.
o Rename a macro-local variable _s to __s in __cpu_simple_lock()
to avoid -Wshadow warning when MALLOC() is used (also declares _s).
o Follow up -Wcast-qual by making a number of function arguments const char*
where string literals are used.
efficient. Instead of using indirect register access, change the
constraint to memory and use the value directly. This allow PC-rel
access among other things.
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
