SVN rev 216406 on 2010-12-13 12:34:35Z by rwatson

Merge r216365 from head to stable/8:

  Derive the XENHVM kernel from GENERIC, adding only the options required
  to support PV drivers (such as xenpci), and non-adptive locking (along
  with a comment about why).

  This change eliminates the synchronisation problem between GENERIC and
  XENHVM, which had become severely rotted in HEAD, and in 8-STABLE
  included non-production kernel debugging features such as WITNESS.

  However, it comes at the cost of enabling devices and options that may
  not be present under Xen (such as random ethernet cards).  For now, opt
  for a simpler kernel configuration file rather than using nooptions/
  nodevice to enumerate and eliminate them.  This leads to a somewhat
  larger XENHVM kernel.

  This is an MFC candidate for 8-STABLE before 8.2, in order to provide
  a production-worthy XENHVM kernel configuration for amd64.

MFC r205014,205015:

Provide groundwork for 32-bit binary compatibility on non-x86 platforms,
for upcoming 64-bit PowerPC and MIPS support. This renames the COMPAT_IA32
option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts
of the kernel and enhances the freebsd32 compatibility code to support
big-endian platforms.

This MFC is required for MFCs of later changes to the freebsd32
compatibility from HEAD.

Remove COMPAT_43TTY from stock kernel configuration files.

COMPAT_43TTY enables the sgtty interface. Even though its exposure has
only been removed in FreeBSD 8.0, it wasn't used by anything in the base
system in FreeBSD 5.x (possibly even 4.x?). On those releases, if your
ports/packages are less than two years old, they will prefer termios
over sgtty.

SVN rev 196198 on 2009-08-13 17:54:11Z by attilio

MFC r196196:

* Completely remove the option STOP_NMI from the kernel.  This option
  has proven to have a good effect when entering KDB by using a NMI,
  but it completely violates all the good rules about interrupts
  disabled while holding a spinlock in other occasions.  This can be the
  cause of deadlocks on events where a normal IPI_STOP is expected.
* Add an new IPI called IPI_STOP_HARD on all the supported architectures.
  This IPI is responsible for sending a stop message among CPUs using a
  privileged channel when disponible. In other cases it just does match a
  normal IPI_STOP.
  Right now the IPI_STOP_HARD functionality uses a NMI on ia32 and amd64
  architectures, while on the other has a normal IPI_STOP effect. It is
  responsibility of maintainers to eventually implement an hard stop
  when necessary and possible.
* Use the new IPI facility in order to implement a new userend SMP kernel
  function called stop_cpus_hard(). That is specular to stop_cpu() but
  it does use the privileged channel for the stopping facility.
* Let KDB use the newly introduced function stop_cpus_hard() and leave
  stop_cpus() for all the other cases
* Disable interrupts on CPU0 when starting the process of APs suspension.
* Style cleanup and comments adding

This patch should fix the reboot/shutdown deadlocks many users are
constantly reporting on mailing lists.

Please don't forget to update your config file with the STOP_NMI
option removal
