Add support for AMD's nested page tables in pmap.c:
- Provide the correct bit mask for various bit fields in a PTE (e.g. valid bit)
for a pmap of type PT_RVI.
- Add a function 'pmap_type_guest(pmap)' that returns TRUE if the pmap is of
type PT_EPT or PT_RVI.
Add CPU_SET_ATOMIC_ACQ(num, cpuset):
This is used when activating a vcpu in the nested pmap. Using the 'acquire'
variant guarantees that the load of the 'pm_eptgen' will happen only after
the vcpu is activated in 'pm_active'.
Add defines for various AMD-specific MSRs.

The "SUB" instruction used in getcc() actually does 'x -= y' so use the

iasl(8) expects integer fields in data tables to be specified as hexadecimal
values. Therefore the bit width of the "PM Timer Block" was actually being
interpreted as 50-bits instead of the expected 32-bit.

Support stopping and restarting the AHCI command list via toggling PxCMD.ST
from '1' to '0' and back. This allows the driver a chance to recover if
for instance a timeout occurred due to activity on the host.
Adjust the test of a KASSERT to better match the intent.
This assertion was added in r246213 as a guard against corrupted mbufs
arriving from drivers, the key distinguishing factor of said mbufs being
that they had a negative length. Given we're in a while loop specifically
designed to skip over zero-length mbufs, panicking on a zero-length mbuf
seems incorrect.

Fix sporadic build failures due to race when running make installworld
when strip gets replaced at install time by adding it to ITOOLS for the

This will fix the failure noted in this Jenkins build step:

on amd64/amd64)

Add ARMV6 as an arm option. This will cause obscure magic in config(8)
to automatically set the armv6 option when MACHINE_ARCH is armv6. That
allows replacing ever-growing lists of cpu names as options to compile
a given file with the using either "optional armv6" or "optional !armv6".
Consider the negation operator (!) to be a word even if it is not followed
by whitespace. This allows "optional !foo" which is what most programmers
are naturally going to tend to do as opposed to "optional ! foo".
Fix the negation (!) operator so that it binds only to the word that
immediately follows it.
