79f4804918 Remove ancient simulation code. Skyeye simulation never really worked
quite right and hasn't been used in ages and is likely broken.  QEMU
with GUMSTIX is a more promising road to FreeBSD/arm in emulation

785f073be9 Modify the experimental NFS server so that it calls
vn_start_write() with a non-NULL vp. That way it will
find the correct mount point mp and use that mp for the
subsequent vn_finished_write() call. Also, it should fail
without crashing if the mount point is being forced dismounted
because vn_start_write() will set the mp NULL via VOP_GETWRITEMOUNT().

7b956487e9 Fix page fault that occurred when trying to initialize preloaded kernel module,
the dependency of which was preloaded, but failed to initialize.  Previously,
kernel dereferenced NULL pointer returned by modlist_lookup2(); now, when this
happens, we unload the dependent module.  Since the depended_files list is
sorted in dependency order, this properly propagates, unloading modules that
depend on failed ones.

From the user point of view, this prevents the kernel from panicing when
trying to boot kernel compiled without KDTRACE_HOOKS with dtraceall_load="YES"
in /boot/loader.conf.

e172464728 On amd64 and i386, tell the compiler to refrain from generating SSE,
3DNow, MMX and floating point instructions in rtld-elf.

Otherwise, _rtld_bind() (and whatever it calls) could possibly clobber
function arguments that are passed in SSE/3DNow/MMX/FP registers,
usually floating point values.  This can happen, for example, when clang
generates SSE code for memset() or memcpy() calls.

One symptom of this is sshd dying early on amd64 with "PRNG not seeded",
which is ultimately caused by libcrypto.so.6 calling RAND_add() with a
double parameter.  That parameter is passed via %xmm0, which gets wiped
out by an SSE memset() in _rtld_bind().

ab19dbcf8d Correct an 8-year-old typo which reliably leads to typo after typo today:
The macros here for generating coprocessor 0 accessors are named like:

	MIPS_RDRW32_COP0

That macro would produce mips_rd_<register>() and mips_wr_<register>()
inlines to access the specified register by name from C.  The problem is that
the R and the W were swapped in the macros originally; it was meant to be named
RDWR because it generated mips_rd_* and mips_wr_* functions, but was instead
spelled RDRW, which nobody should be expected to get right by anything other
than copy and paste.

It's too many consonants in a row to keep straight anyway, so just prefer e.g.:

	MIPS_RW32_COP0

While here, add a missing #undef.

192d74107e Partially revert change made in r212061. r212061 relied on
bus_dma(9)'s capability which honors boundary restrictions of DMA
tag for dynamic buffers. However it seems this does not work well
and it triggered watchodg timeouts on controller that has the
hardware bug. It's not clear whether there is still another
hardware bug not mentioned in errata. This should be revisited
since this change shall make use of bounce buffers which in turn
reduces performance a lot on systems that have more than 4GB
memory.

9a264080b5 Remove OCTEON1-32. Since moving to the Cavium SDK, we've lost our support for
running an o32 kernel safely, and would have to add interrupt disabling and
reenabling to a bunch of macros in the Simple Executive sources to support it.

The only reason one would run an o32 kernel on Octeon would be to run o32 world,
which is better worked towards by adding o32 binary compatibility to n64 kernels
along with, eventually, supporting multilib systems so o32 binaries can run
alongside n32 and n64 ones.

aa829cef6a Add hamfisted locking to the Xen/PV pmap code: Only allow one thread to
be in {pmap_pinit, pmap_copy, pmap_release} at a time.

This reduces the rate of panics when running 'make index' from ~0.6/hour
to ~0.02/hour (p < 10^-30).

At a later date this locking will be removed, and for this reason, it is
wrapped in #ifdef HAMFISTED_LOCKING; this temporary hack is being put in
place with the intention of shipping somewhat-stable Xen bits in FreeBSD
8.2-RELEASE.

Oddly, while this doesn't seem to affect the overall rate of panics
(running 'make index' on EC2 t1.micro instances, there are 0.6 +/- 0.1
panics per hour, both before and after this change), it eliminates
vm_fault from panic backtraces, leaving only backtraces going through
