88737be2dd Teach netstat -Q to work with -N and -M by adding libkvm versions of data
query routines.  This code is necessarily more fragile in the presence of
kernel changes than querying the kernel via sysctl (the default), but
useful when investigating crashes or live kernel state via firewire.

938448cd87 Changes to support crashdump analysis of netisr:
- Rename the netisr protocol registration array, 'np' to 'netisr_proto',
  in order to reduce the chances of symbol name collisions.  It remains
  statically defined, but it will be looked up by netstat(1).

- Move certain internal structure definitions from netisr.c to
  netisr_internal.h so that netstat(1) can find them.  They remain
  private, and should not be used for any other purpose (for example,
  they should not be used by kernel modules, which must instead use the
  public interfaces in netisr.h).

- Store a kernel-compiled version of NETISR_MAXPROT in the global variable
  netisr_maxprot, and export via a sysctl, so that it is available for use
  by netstat(1).  This is especially important for crashdump
  interpretation, where the size of the workstream structure is determined
  by the maximum number of protocols compiled into the kernel.

ccd8bad0bb A first cut at teaching libkvm how to deal with dynamic per-CPU storage
(DPCPU):

A new API, kvm_dpcpu_setcpu(3), selects the active CPU for the purposes
of DPCPU.  Calls to kvm_nlist(3) will automatically translate DPCPU
symbols and return a pointer to the current CPU's version of the data.
Consumers needing to read the same symbol on several CPUs will invoke a
series of setcpu/nlist calls, one per CPU of interest.

This addition makes it possible for tools like netstat(1) to query the
values of DPCPU variables during crashdump analysis, and is based on
similar code handling virtualized global variables.

21fdc27a05 Merge DTC-d75b33af.
This is a split merge because of non-uniform licensing of the DTC package
contents and the way these components will be used in the FreeBSD environment.

The original DTC package is composed of the following two major pieces:

1. sys/contrib/libfdt (BSD [dual] license)
2. contrib/dtc (GPLv2)

The libfdt component is going to be shared in all aspects of the environment:
- /boot/loader
- kernel
- dtc (the device tree compiler proper, userspace tool)

db811dd724 Fix the race between dotdot lookup and forced unmount, by using
msdosfs-specific variant of vn_vget_ino(), msdosfs_deget_dotdot().

As was done for UFS, relookup the dotdot denode after the call to
msdosfs_deget_dotdot(), because vnode lock is dropped and directory
might be moved.

740a720142 In msdosfs_inactive(), reclaim the vnodes both for SLOT_DELETED and
SLOT_EMPTY deName[0] values. Besides conforming to FAT specification, it
also clears the issue where vfs_hash_insert found the vnode in hash, and
newly allocated vnode is vput()ed. There, deName[0] == 0, and vnode is
not reclaimed, indefinitely kept on mountlist.

22e62e7e6e In both if_tun and if_tap:
Do not do additional dev_ref() on the newly created interface in the
if_clone create method [1]. This reference is not needed and never
removed, causing struct cdevpriv leakage. Remove the setting of
SI_CHEAPCLONE flag as well, since it is unused.

For dev_clone handlers, create cdevs with the call make_dev_credf(MAKEDEV_REF)
instead of calling make_dev() and then dev_ref(), to avoid a race.

Call drain_dev_clone_events() at the module unload time after dev_clone
handler is deinstalled.

o  Remove the sapicreg.h and sapicvar.h headers. All definitions

0b993ee5fd When running as a guest operating system, the FreeBSD kernel must assume
that the virtual machine monitor has enabled machine check exceptions.
Unfortunately, on AMD Family 10h processors the machine check hardware
has a bug (Erratum 383) that can result in a false machine check exception
when a superpage promotion occurs.  Thus, I am disabling superpage
promotion when the FreeBSD kernel is running as a guest operating system
on an AMD Family 10h processor.
