ab61b53b27 Adjust the sleeps in lwpcache and lwpublk. Make them uninterruptable 
for now. This will prevent signals from waking them. Adjust
exit_lwps() to explicitly add LW_SINTR to all of them, so that
the process exit code can wake them up.

This is needed as threads in both of these wait channels die once
they are woken. So they aren't interruptable in the typical sense.

04ca26c586 Tweak change to move SA support from userret() to lwp_userret(). 
1) Since we want to check for upcalls only once, take LW_SA_UPCALL
out of the while(l->l_flags & LW_USERRET) loop.

2) since the goal is to keep SA code out of userret() (and especially
all the emulations that include userret() but will never do SA),
ALWAYS set LW_SA_UPCALL when we set SAVP_FLAG_NOUPCALLS. Drop the
test for it in lwp_userret() since it will never be set bare.

3) Adapt sa_upcall_userret() to clear LW_SA_UPCALL if it's no longer
needed. If we have gained upcalls since sa_yield(), we will deliver
them next time around.

Tested by skrll at.

1698883b6a Ok. Some calls to sa_upcall() pass in an 'l' that is not the current

can't access l->l_pflag. So access curlwp for the no-upcall-blocking

27724c38ae Adjust locking on the sadata::sa_vps list. The main time we 
walk the list, we're looking for a vp to do something with. We do
this in the signal code and in the timer code. The signal code already
runs with proc::p_lock held, so it's a very natural lock to use. The
timer code, however, calls into the sa timer code with a spinlock held.
Since proc::p_lock is an adaptable mutex, we can sleep to get it. Sleeping
with a spinlock is BAD. So proc::p_lock is _not_ the right lock there,
and something like sadata::sa_mutex would be best.

Address this difficulty by noting that both uses actually just read
the list. Changing the list of VPs is rare - once one's added, it stays
until the process ends. So make the locking protocol that to write the
list you have to hold both proc::p_lock and sadata::sa_mutex (taken
in that order). Thus holding either one individually grants read access.

This removes a case where we could sleep with timer_lock, a spinlock at
IPL_SCHED (!!), while trying to get p_lock. If that ever happened, we'd
pretty much be dead. So don't do that!

This fixes a merge botch from how I handled our gaining p_lock - p_lock
should not have simply replaced p_smutex.

While here, tweak the sa_unblock_userret() code for the case
when the blessed vp is actually running (on another CPU). Make its
resched RESCHED_IMMED so we whack the CPU. Addresses a hang I've
observed in starting firefox on occasion when I see one thread running
in userland and another thread sitting in lwpublk, which means it's on
the list of threads for which we need an unblocked upcall. This list is
one on which things should NOT linger.

42d0626726 PR kern/38141 lookup/vfs_busy acquire rwlock recursively 
Simplify the mount locking. Remove all the crud to deal with recursion on
the mount lock, and crud to deal with unmount as another weirdo lock.

Hopefully this will once and for all fix the deadlocks with this. With this
commit there are two locks on each mount:

- krwlock_t mnt_unmounting. This is used to prevent unmount across critical
  sections like getnewvnode(). It's only ever read locked with rw_tryenter(),
  and is only ever write locked in dounmount(). A write hold can't be taken
  on this lock if the current LWP could hold a vnode lock.

- kmutex_t mnt_updating. This is taken by threads updating the mount, for
  example when going r/o -> r/w, and is only present to serialize updates.
  In order to take this lock, a read hold must first be taken on
  mnt_unmounting, and the two need to be held across the operation.

One effect of this change: previously if an unmount failed, we would make a
half hearted attempt to back out of it gracefully, but that was unlikely to
work in a lot of cases. Now while an unmount that will be aborted is in
progress, new file operations within the mount will fail instead of being
delayed. That is unlikely to be a problem though, because if the admin
requests unmount of a file system then s(he) has made a decision to deny
access to the resource.

e3610f1886 kern/38135 vfs_busy/vfs_trybusy confusion 
The symptom was that sometimes file systems would occasionally not appear
in output from 'df' or 'mount' if the system was busy. Resolution:

- Make mount locks work somewhat like vm_map locks.
- vfs_trybusy() now only fails if the mount is gone, or if someone is
  unmounting the file system. Simple contention on mnt_lock doesn't
  cause it to fail.
- vfs_busy() will wait even if the file system is being unmounted.

6d70f903e6 Network protocol interrupts can now block on locks, so merge the globals 
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

2a9368a7e7 In linux_sys_sched_getparam(), get the native policy too, so that we have 
a better chance at properly converting the priority.

Noted by & okay yamt@.

67470a76a1 Factor out the guts of get/setparam so it can be used from the compat code. 
Make the FreeBSD and Linux compat code convert the parameters to their
native representation and call the native routines.

Remove KAUTH_PROCESS_SCHEDULER_GET/SET.

Update documentation and examples.

XXX: For now, only the Linux compat code does the priority conversion
XXX: right.

Linux priority conversion code from yamt@, thanks!

Okay yamt@.

e99760e7e4 Fold KAUTH_REQ_PROCESS_SCHEDULER_* to KAUTH_PROCESS_SCHEDULER_*. In other 
words, don't pass an action and a request, and just use a single action to
indicate what is the operation in question.

This is the first step in fixing PR/37986, which calls for policy/priority
checking in the secmodel code. Right now we're lacking room for another
parameter required to make a decision, and this change makes room for such.
