There is a small race condition in this patch which could cause
problems if a signal arrives after setting the (kernel) signal
mask and before exec'ing. The thread's set of pending signals
also are not yet installed in the exec'd process. Both of these
will be corrected with the addition of a special syscall.

On the other hand, __isnanl() must live in libm because libm uses it

but with slightly cleaned up interfaces.
The KSE structure has become the same as the "per thread scheduler
private data" structure. In order to not make the diffs too great
one is #defined as the other at this time.
The KSE (or td_sched) structure is now allocated per thread and has no
allocation code of its own.
Concurrency for a KSEGRP is now kept track of via a simple pair of counters
rather than using KSE structures as tokens.
Since the KSE structure is different in each scheduler, kern_switch.c
is now included at the end of each scheduler. Nothing outside the
scheduler knows the contents of the KSE (aka td_sched) structure.
The fields in the ksegrp structure that are to do with the scheduler's
queueing mechanisms are now moved to the kg_sched structure.
(per ksegrp scheduler private data structure). In other words how the
scheduler queues and keeps track of threads is no-one's business except
the scheduler's. This should allow people to write experimental
schedulers with completely different internal structuring.
A scheduler call sched_set_concurrency(kg, N) has been added that
notifies teh scheduler that no more than N threads from that ksegrp
should be allowed to be on concurrently scheduled. This is also
used to enforce 'fainess' at this time so that a ksegrp with
10000 threads can not swamp a the run queue and force out a process
with 1 thread, since the current code will not set the concurrency above
NCPU, and both schedulers will not allow more than that many
onto the system run queue at a time. Each scheduler should eventualy develop
their own methods to do this now that they are effectively separated.

extensions, this code was checking the truncated filename stored in the
regular header rather than the full filename stored in the extended

position would trigger this check and be erroneously marked as
directories. Move the check so it only considers the full filename.
Note: the check can't simply be disabled for archives that contain

_mcount() stub when profiling is enabled. Emit this code sequence

We do not pass the GOT entry however as the 4th argument, because it's
not used. The _mcount() stub calls __mcount(), which does the actual
work. Define _MCOUNT_DECL to define __mcount. We do not have an
implementation of mcount(), so we define MCOUNT as empty, but have a
weak alias to _mcount() in _mcount.S.
Note that the _mcount() stub in the kernel is slightly different from
the stub in userland. This is because we do not have to worry about
nested routines in the kernel.
64 bit systems, years roughly -2^31 through 2^31 can be represented in
time_t without any trouble. 32 bit time_t systems only range from
roughly 1902 through 2038. As a consequence, none of the date munging
code for all the various calendar tweaks before then is present. There
are other problems including the fact that there was no 'year zero' and
so on. So rather than get excited about trying to figure out when the
calendar jumped by two weeks etc, simply disallow negative (ie: prior to
1900) years.
This happens to have an important side effect. If you bzero a 'struct
tm', it corresponds to 'Jan 0, 1900, 00:00 GMT'. This happens to be
representable (after canonification) in 64 bit time_t space. Zero tm
structs are generally an error and mktime normally returns -1 for them.
Interestingly, it tries to canonify the 'jan 0' to 'dec 31, 1899', ie:
year -1. This conveniently trips the negative year test above, which
means we can trivially detect the null 'tm' struct.
This actually tripped up code at work. :-/ (Don't ask)
