926297fefb Update elf_common.h with new EM_ types found in the latest ELF gABI.
This commit is slightly different from the original patch in the PR:
1. EM_ALPHA keeps the old value for compatibility reason.
2. Non-standard SHT_NUM is not added.
3. Style.

owned by the current user.  If kinfo_getfile() or kinfo_getvmmap() return
NULL, simply exit, and do not try and derefernce the memory.

e657c679e1 The ppp application relies on the if_tun interface to properly
install a p2p host route between the end points. The ppp module
upates this router based on user configuration later on. The
rt_Update() seems to always set the RTF_GATEWAY flag, which is
broken.

c9e7b21284 We only want drm to ever attach to the primary pci device.
Intel 855 chips present the same pci id for both heads.  This prevents
us from attaching to the dummy second head.  All other chips that I
am aware of either only present a single pci id, or different ids
for each head so that we only match on the correct head.

f6550fad4d Before modularization commit, atapci driver was attaching only to devices of

but as it was reported on current@, it does important for sis driver and
surely inportant for AHCI driver. So restore it there.

8b8df0ff61 rework drm_scatter.c which allocates scatter / gather pages for use by
ati pci gart to use bus_dma to handle the allocations.  This fixes
a garbled screen issue on at least some radeons (X1400 tested).  It is
also likely that this is the correct fix for PR# 119324, though that
is not confirmed yet.

5773d864f9 - Failing to register as interrupt controller during attach shouldn't
be fatal so just inform about this instead of panicing.
- Ensure we use the right softc in case the interrupt of a child is
  is routed to the companion PBM instead. This hasn't been seen in the
  wild so far but given that it's the case for the Schizo interrupts,
  handling this situation also for child interrupts as a precaution
  seemed a good idea.
- Deal with broken firmware versions which miss child entries in the
  ino-bitmap as seen on V880 by belatedly registering as interrupt
  controller in schizo_setup_intr(). [1]
- Add missing '\n' when printing the warning regarding Schizo Errata
  I-13.

548066ea66 The quotactl, statfs and fstatfs syscall implementations may dereference
NULL pointer to struct mount if the looked up vnode is reclaimed. Also,
these syscalls only mnt_ref() the mp, still allowing it to be unmounted;
only struct mount memory is kept from being reused.

Lock the vnode when doing name lookup, then reference its mount point,
unlock the vnode and vfs_busy the mountpoint. This sequence shall take
care of both races.

3dc309114a Introduce a sysctl kern.vm_guest that reflects what the kernel knows about
it running under a virtual environment. This also introduces a globally
accessible variable vm_guest that can be used where appropriate in the
kernel to inspect this environment.

To make it easier for the long run, an enum VM_GUEST is also introduced,
which could possibly be factored out in a header somewhere (but the
question is where - vm/vm_param.h? sys/param.h?) so it eventually becomes
a part of the standard KPI. In any case, it's a start.

The purpose of all this isn't to absolutely detect that the OS is running
under a virtual environment (cf. "redpill") but to allow the parts of the
kernel and the userland that care about this particular aspect and can do
something useful depending on it to have a standardised interface. Reducing
kern.hz is one example but there are other things that could be done like
avoiding context switches, not using CPU instructions that are known to be
slow in emulation, possibly different strategies in VM (memory) allocation,
CPU scheduling, etc.

It isn't clear if the JAILS/VIMAGE functionality should also be exposed
by this particular mechanism (probably not since they're not "full"
virtual hardware environments). Sometime in the future another sysctl and
a variable could be introduced to reflect if the kernel supports any kind
of virtual hosting (e.g. VMWare VMI, Xen dom0).
