d3dabe1260 Add IPC_64 support for all semctl(2)/msgctl(2). Needed, at least on

4d8f47ae2f cpuctl: 
- Add interrupt shielding (direct hardware interrupts away from the
  specified CPUs). Not documented just yet but will be soon.

- Redo /dev/cpu time_t compat so no kernel changes are needed.

x86:

- Make intr_establish, intr_disestablish safe to use when !cold.

- Distribute hardware interrupts among the CPUs, instead of directing
  everything to the boot CPU.

- Add MD code for interrupt sheilding. This works in most cases but there is
  a bug where delivery is not accepted by an LAPIC after redistribution. It
  also needs re-balancing to make things fair after interrupts are turned
  back on for a CPU.

2d1c968399 Remove a few KAUTH_GENERIC_ISSUSER in favor of more descriptive 
alternatives.

Discussed on tech-kern:

c6367674d6 Add fileops::fo_drain(), to be called from fd_close() when there is more 
than one active reference to a file descriptor. It should dislodge threads
sleeping while holding a reference to the descriptor. Implemented only for
sockets but should be extended to pipes, fifos, etc.

Fixes the case of a multithreaded process doing something like the
following, which would have hung until the process got a signal.

thr0	accept(fd, ...)
thr1	close(fd)

fcc023545e - add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total 
address space available to processes.  this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.

- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.

- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)

- patch sh, and csh to notice RLIMIT_AS.  (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)

- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.

- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information.  (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)


this addresses PR 7897.  it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.

tested on i386 and sparc64, build tested on several other platforms.

thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

d16d704d62 PR port-i386/40143 Viewing an mpeg transport stream with mplayer causes crash 
Fix numerous problems:

1. LDT updates are not atomic.

2. Number of processes running with private LDTs and/or I/O bitmaps
   is not capped. System with high maxprocs can be paniced.

3. LDTR can be leaked over context switch.

4. GDT slot allocations can race, giving the same LDT slot to two procs.

5. Incomplete interrupt/trap frames can be stacked.

6. In some rare cases segment faults are not handled correctly.

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.

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.

7408df1239 Change {ff,fd}_exclose and ff_allocated to bool. Change exclose arg to 
fd_dup to bool.  Switch assignments from 1/0 to true/false.

This make alpha kernels compile.  Bump kern to 4.99.69 since structure
changed.

unsigned int.
