897f1917a4 In the case when reset via keyboard controller doesn't work for some reason
(i.e. no keyboard controller present), try two other common methods for
resetting i386 machine - pci reset and port 0x92 fast reset. Only if neither
works warn user and resort to "unmap entire address space and hope for good"
hack. This makes my MacBook Pro rebooting just fine and should also help
other legacy-free hardware out there.

Also, disable interrupts unconditionally in cpu_reset_real(), since we don't
want any interference.

f7768b9f34 Change the semantics of brk_max to dynamically deal with data segment
bounds. [1]

Modify logic for utilizing the data segment, such that it is possible to
create huge allocations there.

Shrink the data segment when deallocating a chunk, if it is at the end of
the data segment.

Rename chunk_size to csize in huge_malloc(), in order to avoid masking a
static variable of the same name. [1]

041a991fa7 MFamd64: shrink pv entries from 24 bytes to about 12 bytes. (336 pv entries
per page = effectively 12.19 bytes per pv entry after overheads).
Instead of using a shared UMA zone for 24 byte pv entries (two 8-byte tailq
nodes, a 4 byte pointer, and a 4 byte address), we allocate a page at a
time per process.  This provides 336 pv entries per process (actually, per
pmap address space) and eliminates one of the 8-byte tailq entries since
we now can track per-process pv entries implicitly.  The pointer to
the pmap can be eliminated by doing address arithmetic to find the metadata
on the page headers to find a single pointer shared by all 336 entries.
There is an 11-int bitmap for the freelist of those 336 entries.

This is mostly a mechanical conversion from amd64, except:
* i386 has to allocate kvm and map the pages, amd64 has them outside of kvm
* native word size is smaller, so bitmaps etc become 32 bit instead of 64
* no dump_add_page() etc stuff because they are in kvm always.
* various pmap internals tweaks because pmap uses direct map on amd64 but
  on i386 it has to use sched_pin and temporary mappings.

Also, sysctl vm.pmap.pv_entry_max and vm.pmap.shpgperproc are now
dynamic sysctls.  Like on amd64, i386 can now tune the pv entry limits
without a recompile or reboot.

This is important because of the following scenario.   If you have a 1GB
file (262144 pages) mmap()ed into 50 processes, that requires 13 million
pv entries.  At 24 bytes per pv entry, that is 314MB of ram and kvm, while
at 12 bytes it is 157MB.  A 157MB saving is significant.

6621aa5cc7 Use the same method for detecting actual presence of AT-style keyboard
controller as we use in boot blocks (querying status register until
bit 1 goes off). If that doesn't happed during reasonable period assume
that the hardware doesn't have AT-style keyboard controller. This makes
FreeBSD working almost OOB on MacBook Pro (still there are issues with
putting second CPU core on-line, but since installation CD comes with
UP kernel with this change one should be able to install FreeBSD without
playing tricks with hints). Other legacy-free hardware (e.g. IBM NetVista
S40) should benefit from this as well, but since I don't have any I can't
verify.

It should make no difference on the ordinary i386 hardware (since in
that case that hardware already would be having an issues with A20
routines in boot blocks). I don't know much about AT-style keyboard
controller on other platforms (and don't have dedicated access to one),
therefore, the code is restricted to i386 for now. I suspect that amd64
may need this as well, but I would rather leave this decision to someone
who knows better about the platform(s) in question.

I have tested this change on as many "ordinary i386 boxes" as I can get
my hands on, and it doesn't create any false negatives on hardware with
AT-style keyboard present.

c9a08d1cad - Overhaul the 'ps' command in ddb to be mostly readable again. :) It is
now back to using fixed-size columns for output and each line of output
  should fit in 80 columns on both 32-bit and 64-bit architectures.  In
  general the output is close to that of the userland ps(1) with the
  exception that the 'wmesg' field is mostly similar to the "state" field
  in top(1) in that it will show either a wmesg, a lock name (prefixed with
  an *), "CPU xx" (for a running thread), or nothing if none of those three
  conditions are true.  It also respects td_name when listing threads in
  a multithreaded process.  There is a somewhat evilly-defined PTR64 macro
  I use to make account for the change in the size of the 'wchan' column
  in the formatted output (wchan is now the only pointer in the ps output
  and is available so it can be passed to 'show sleepq', 'show turnstile',
  or 'show lock').
- Add two new commands "show proc [process]" and "show thread [thread]"
  that show details about the specified process or thread (specified
  either by pid/tid or pointer), respectively.  If an address it not
  specified, it uses the current kdb thread.

ae110b53d1 Add some new commands to hopefully make it easier to diagnose lock-related
problems in ddb:
- "show threadchain [thread]" will start with the specified thread (or the
  current kdb thread by default) and show it's state.  If it is blocked on
  a lock, it will find the owner of the lock and show its state, etc.
- "show allchains" will find all of the threads that are blocked on a
  lock (but do not have any threads blocked on a lock they hold) and show
  the resulting thread chain.
- "show lockchain <lock>" takes a pointer to a lock_object (such as a
  mutex or rwlock).  If there is a turnstile for that lock, then it will
  display all the threads blocked on the lock.  In addition, for each
  thread blocked on the lock, it will display any contested locks they
  hold, and recurse on those locks to show any threads blocked on those
  locks, etc.

de833b7c0c Use db_lookup_thread() to lookup the thread for the passed in address
and change 'show locks' to only list the locks for a given thread

thread.

d605beaaa8 Add two helper functions: db_lookup_thread() and db_lookup_proc(). They
take the addr value passed to a ddb command and attempt to use it to
lookup a struct thread * or struct proc *, respectively.  Each function
first reparses the passed in value as if it was an ID entered in base 10.
For threads the ID is treated as a thread ID, for proceses the ID is
treated as a PID.  If a thread or proc matching the ID is found, it is
returned.  For db_lookup_thread(), if the check_pid argument is true and
it didn't find a thread with a matching thread ID, it will treat the ID as
a PID and look for a matching process.  If it finds one it returns the
first thread in the process.  If none of the ID lookups succeeded, then
the functions assume that the passed in address is a thread or proc
pointer, respectively.  This allows one to use tids, pids, or structure
pointers interchangeably in ddb functions that want to lookup threads or
processes if desired.

102ea03373 Extend getsock() to return the struct file flags read while holding the
file lock, in the style of fgetsock().

Modify accept1() to use getsock() instead of fgetsock(), relying on the
file descriptor reference rather than an acquired socket reference to
prevent the listen socket from being destroyed during accept().  This
avoids additional reference count operations, which should improve
performance, and also avoids accept1() operating on a socket whose file
descriptor has been torn down, which may have resulted in protocol
shutdown starting.

into in_pcbdrop().  Expand logic to detach the inpcb from its bound

reservation, which since the introduction of socket/pcb reference count
updates, has been persisting until the socket closed rather than being
released implicitly due to prior freeing of the inpcb on TCP drop.

8b4553119e Adjust dangerous-shared-cache-detection logic from "all shared data
caches are dangerous" to "a shared L1 data cache is dangerous".  This
is a compromise between paranoia and performance: Unlike the L1 cache,
nobody has publicly demonstrated a cryptographic side channel which
exploits the L2 cache -- this is harder due to the larger size, lower
bandwidth, and greater associativity -- and prohibiting shared L2
caches turns Intel Core Duo processors into Intel Core Solo processors.

As before, the 'machdep.hyperthreading_allowed' sysctl will allow even
the L1 data cache to be shared.
