9cf8dd43cf Complete the removal of __FreeBSD_version checks from the amr driver. The
driver had advanced enough over the years that direct sharing of code with
FreeBSD 4.x was in no way possible anymore.

2069c3305d Back-out previous commit - we need to skip logging socket when we start a
jail and external syslogd is listening in jail's chroot.

d365f9c760 Cleanup beacon/listen interval handling:
o separate configured beacon interval from listen interval; this
  avoids potential use of one value for the other (e.g. setting
  powersavesleep to 0 clobbers the beacon interval used in hostap
  or ibss mode)
o bounds check the beacon interval received in probe response and
  beacon frames and drop frames with bogus settings; not clear
  if we should instead clamp the value as any alteration would
  result in mismatched sta+ap configuration and probably be more
  confusing (don't want to log to the console but perhaps ok with
  rate limiting)
o while here up max beacon interval to reflect WiFi standard

5b3e518936 Skip jails which are already running and inform why.
We're checking for /var/run/jail_<name>.id file and if it exists, we don't
start the jail. It should be also safe in case of reboot(8), because
rc.d/cleanvar script is going to remove /var/run/jail_* files.

It helps to avoid potential mess when the same jail is started twice,
because of an administrator mistake (been there, done that).

ea16133887 We don't need to skip /var/run/log socket, as syslogd is always started
after rc.d/cleanvar. And if we wanted to skip /var/run/log we still needed
to skip /var/run/logpriv, which wasn't implemented.

5f2c46d5ed When support for 2MB/4MB pages was added in revision 1.148 an error was
made in pmap_protect(): The pmap's resident count should not be reduced
unless mappings are removed.

The errant change to the pmap's resident count could result in a later
pmap_remove() failing to remove any mappings if the errant change has set
the pmap's resident count to zero.

tokenizer.c:1.3).  Contrary to the commit log there were no memory leaks,
but the change introduced a bug because the free'd pointer was not zeroed
and calling the appropriate _end() function would call free() a second time.

4630415a47 Improve SMP support:
o  Allocate a VHPT per CPU. The VHPT is a hash table that the CPU
   uses to look up translations it can't find in the TLB. As such,
   the VHPT serves as a level 1 cache (the TLB being a level 0 cache)
   and best results are obtained when it's not shared between CPUs.
   The collision chain (i.e. the hash bucket) is shared between CPUs,
   as all buckets together constitute our collection of PTEs. To
   achieve this, the collision chain does not point to the first PTE
   in the list anymore, but to a hash bucket head structure. The
   head structure contains the pointer to the first PTE in the list,
   as well as a mutex to lock the bucket. Thus, each bucket is locked
   independently of each other. With at least 1024 buckets in the VHPT,
   this provides for sufficiently finei-grained locking to make the
   ssolution scalable to large SMP machines.
o  Add synchronisation to the lazy FP context switching. We do this
   with a seperate per-thread lock. On SMP machines the lazy high FP
   context switching without synchronisation caused inconsistent
   state, which resulted in a panic. Since the use of the high FP
   registers is not common, it's possible that races exist. The ia64
   package build has proven to be a good stress test, so this will
   get plenty of exercise in the near future.
o  Don't use the local ID of the processor we want to send the IPI to
   as the argument to ipi_send(). use the struct pcpu pointer instead.
   The reason for this is that IPI delivery is unreliable. It has been
   observed that sending an IPI to a CPU causes it to receive a stray
   external interrupt. As such, we need a way to make the delivery
   reliable. The intended solution is to queue requests in the target
   CPU's per-CPU structure and use a single IPI to inform the CPU that
   there's a new entry in the queue. If that IPI gets lost, the CPU
   can check it's queue at any convenient time (such as for each
   clock interrupt). This also allows us to send requests to a CPU
   without interrupting it, if such would be beneficial.

With these changes SMP is almost working. There are still some random
process crashes and the machine can hang due to having the IPI lost
that deals with the high FP context switch.

The overhead of introducing the hash bucket head structure results
in a performance degradation of about 1% for UP (extra pointer
indirection). This is surprisingly small and is offset by gaining
reasonably/good scalable SMP support.

045f23cd0d Reduce the default MAXCPU from 16 to 4. This is in preparation of
allocating a VHPT per CPU. Since we don't yet know how many CPUs
are actually in the system at the time we need to allocate the
VHPTs, we allocate for MAXCPU processors. This can result in a
lot of wasted space for 2-way machines. So, for now, limit MAXCPU
to something smaller until we have something more dynamic.

cbef4d0edc For ia64_ptc_{e,g,ga,l}(), use instruction serialization. We

688deacdfa o Remove the obscure tid command, because it does what the thread
command does, but worse.
o  Remove the obscure proc command, because it does what the thread
   command does, but not unambigously.
o  Move the PID to the extra thread info, where it makes sense and
   where it doesn't confuse users. The extra thread info holds some
   process information, to which the PID belongs.
o  Implement the to_find_new_threads target method by having it call
   the target beneath us if we're not using KVM. This makes sure that
   new threads are found when using the remote target.

o  Fix various core dump scenarios:
   -  Implement the to_files_info target method. Previously the
      'info target' command would cause a NULL pointer dereference.
   -  Don't assume there's a current thread. We're not initialized
      in all cases. This prevents a NULL pointer dereference.
   -  When we're not ussing KVM, have the to_xfer_memory target
      method call the target beneath us. This avoids calling into
      KVM with a NULL pointer.

ba23fa9bd8 Teach libmemstat(3) how to extract malloc(9) statistics using kvm(3),
so that libmemstat can be used to view full memory statistics from
kernel core dumps and /dev/mem.  This is provided via a new query
function, memstat_kvm_malloc(), which is also automatically invoked
by memstat_kvm_all().  A kvm handle must be passed in.

This will allow malloc(9)-specific code to be removed from vmstat(8).
