890577ec23 Pull in r200899 from upstream clang trunk:
Allow transformation of VariableArray to ConstantArray.

  In the following code:

     struct A { static const int sz; };
     template<class T> void f() { T arr[A::sz]; }

  the array 'arr' is represented as a variable size array in the template.
  If 'A::sz' gets value below in the translation unit, the array in
  instantiation can turn into constant size array.

  This change fixes PR18633.

  Differential Revision: http://llvm-reviews.chandlerc.com/D2688

This fixes "Assertion failed: (T::isKind(*this)), function castAs"
errors, which can occur when building the security/quantis port.

1d20cbce2a Build libstand as a 64-bit library on ppc64
The 32-bit bootloaders now link against libstand.a in sys/boot/libstand32,
so there is no need to force /usr/lib/libstand.a to be 32-bit.

This is equivalent to r261568 for amd64.

0a3cc34ebf It turns out a global variable is the only straightforward way to
communicate the kernel's physical load address from where it's known in
initarm() into cpu_mp_start() which is called from non-arm code and
takes no parameters.

This adds the global variable and ensures that all the various copies
of initarm() set it.  It uses the variable in cpu_mp_start(), eliminating
the last uses of KERNPHYSADDR outside of locore.S (where we can now
calculate it instead of relying on the constant).

30d95028f0 Consolidate code related to setting up physical memory configuration into
a new physmem.c file.  The new code provides helper routines that can be
used by legacy SoCs and newer FDT-based systems.  There are routines to
add one or more regions of physically contiguous ram, and exclude one or
more physically contiguous regions of ram.  Ram can be excluded from crash
dumps, from being given over to the vm system for allocation management,
or both.  After all the included and excluded regions have been added,
arm_physmem_init_kernel_globals() processes the regions into the global
dump_avail and phys_avail arrays and realmem and physmem variables that
communicate memory configuration to the rest of the kernel.

Convert all existing SoCs to use the new helper code.

5da54698fa Remove the ARM_USE_SMALL_ALLOC option and code related to it.
This was an optimization used only by a few xscale platforms.  Part of
the optimization was to create a direct map for all physical pages, and
that resulted in making multiple mappings of pages in a way that bypassed
the logic in pmap.c to handle VIVT cache aliasing.  It also just generally
made the code more complex and hard to maintain for all SoCs.

0cdfc370bf Add virtualized XSAVE support to bhyve which permits guests to use XSAVE and
XSAVE-enabled features like AVX.
- Store a per-cpu guest xcr0 register.  When switching to the guest FPU
  state, switch to the guest xcr0 value.  Note that the guest FPU state is
  saved and restored using the host's xcr0 value and xcr0 is saved/restored
  "inside" of saving/restoring the guest FPU state.
- Handle VM exits for the xsetbv instruction by updating the guest xcr0.
- Expose the XSAVE feature to the guest only if the host has enabled XSAVE,
  and only advertise XSAVE features enabled by the host to the guest.
  This ensures that the guest will only adjust FPU state that is a subset
  of the guest FPU state saved and restored by the host.

The tracking generated warnings when the line number of an existing tty in
/etc/ttys changed, which would corrupt utmp (as it was indexed by the line
number). With utmpx, the line number no longer matters, so the tracking is
no longer needed.

4574 get_clones_stat does not call zap_count in non-debug kernel

zap_count(...) is never called in non-DEBUG kernel.
As result "count" variable is always 0, and "goto fail" is always
reached.  This means get_clones_stat function never makes up list
of clones for "clones" properties.

d79f5b61e6 Fix a bug in the handling of VM-exits caused by non-maskable interrupts (NMI).
If a VM-exit is caused by an NMI then "blocking by NMI" is in effect on the
CPU when the VM-exit is completed. No more NMIs will be recognized until
the execution of an "iret".

Prior to this change the NMI handler was dispatched via a software interrupt
with interrupts enabled. This meant that an interrupt could be recognized
by the processor before the NMI handler completed its execution. The "iret"
issued by the interrupt handler would then cause the "blocking by NMI" to
be cleared prematurely.

This is now fixed by handling the NMI with interrupts disabled in addition
to "blocking by NMI" already established by the VM-exit.
