48052f99e7 - Use a custom version of copyinuio() to implement readv/writev using 
kern_readv/writev.
- Use kern_settimeofday() and kern_adjtime() rather than stackgapping it.

503e759c5d MFR5: rev 1.421.2.6: Enable support for 32-bit Linux binaries by default. 
There are too many questions in freebsd-amd64@ about how to enable Linux
support that it seems a required piece of functionality.  Thus we should
just have it on by default.

b80ed61487 Don't recursively panic when we call mi_switch() in a critical section, 
even though calling mi_switch() after a panic is likely a bug anyway as
the recursive panic only serves to make things worse.

f1c579b1ec Add the Areca SATA RAID driver (arcmsr). This supports the ARC-11xx and 12xx 
series of controllers.  Areca provides a CLI and HTTP management tool for
FreeBSD/i386 and FreeBSD/amd64 on their website.  Many thanks to Areca for
their support of FreeBSD.  Thanks also to Mike Tansca and Sentex Communications
for donating hardware.

621b33fc5b Fix an amd64 issue I overlooked. When setting up a callout to 
ndis_timercall() in NdisMInitializeTimer(), we can't use the raw
function pointer. This is because ntoskrnl_run_dpc() expects to
invoke a function with Microsoft calling conventions. On i386,
this works because ndis_timercall() is declared with the __stdcall
attribute, but this is a no-op on amd64. To do it correctly, we
have to generate a wrapper for ndis_timercall() and us the wrapper
instead of of the raw function pointer.

Fix this by adding ndis_timercall() to the funcptr table in subr_ndis.c,
and create ndis_findwrap() to extract the wrapped function from the
table in NdisMInitializeTimer() instead of just passing ndis_timercall()
to KeInitializeDpc() directly.

b641353e3a - Remove apause(). It makes no sense with our present mutex implementation 
since simply unlocking a mutex does not ensure that one of the waiters
   will run and acquire it.  We're more likely to reacquire the mutex
   before anyone else has a chance.  It has also bit me three times now, as
   it's not safe to drop the interlock before sleeping in many cases.

58aa36f31e Checkpoint today's tidy-up of the WIP disassembler. It now agrees with 
objdump --disassemble when disassembling itself in userland.  I've added
the cmovCC instruction group and tweaked a bunch of size sensitive array
indexes to either fix my mistakes and/or force it to work by any means
necessary.

I'm committing this because it is usable enough to see what is going on
when single stepping via ddb.

It might still tell lies, but its lies will be far more subtle now.  I'm
not sure that this is a good thing or not.
