The data in MODINFOMD_MODULEP is packed by the loader as a 4 byte type, but
the amd64 kernel expects a vm_paddr_t, which is of size 8 bytes. Fix this by
saving it as 8 bytes in the loader and retrieving it using the proper type
in the kernel.

Prior to this change CLOCK_MONOTONIC could go backwards when the timecounter
hardware was changed via 'sysctl kern.timecounter.hardware'. This happened
because the vdso timehands update was missing the special treatment in
tc_windup() when changing timecounters.

These instructions are emitted by 'bus_space_read_region()' when accessing
MMIO regions.
Since MOVS can be used with a repeat prefix start decoding the REPZ and
REPNZ prefixes. Also start decoding the segment override prefix since MOVS
allows overriding the source operand segment register.

the 'gpa' was in the guest MMIO region. This would manifest as a segmentation
fault in 'vm_map_copyin()' or 'vm_map_copyout()' because 'vm_map_gpa()' would
return NULL for this 'gpa'.
Fix this by calling 'vm_map_gpa()' in 'vm_copy_setup' and returning a failure
if the 'gpa' cannot be mapped. This matches the behavior of 'vm_copy_setup()'
in vmm.ko.

in the "hosts" array and eventually looks up the network address with
getaddrinfo(). At one point it checks for a numeric address and if it
sees one, it sets a hint parameter to force getaddrinfo to interpret the
host as a numeric address. However that hint is not cleared for subsequent
iterations of the loop and if any hosts seen after this point are host names,
getaddrinfo will fail on the name. The result of this bug is that you cannot
pass a host name to the -h flag.
Unfortunately, the first iteration will either process ::1 or 127.0.0.1,
so the flag is set on the first iteration and all host names will fail
to be processed.
The same bug applies to rpc.lockd and rpc.statd, so fix them too.

A number of entries that can be present in the spa config shouldn't be saved
to disk so add a method to ensure this is case. Without this if the last
caller to vdev_config_generate requested stats then we can end up in the
cache file.
Also only skip a none writable pool in the cache file generation if its
active. This prevents unavailable pools incorrectly getting removed from
cache file.

This doesn't actually change any behavior, because it just allows a 16-bit
read of the command register to return the correct value, and nothing
actually does a 16-bit read of that register.
After the ext2 variant of the "orlov allocator" was implemented,
the case for a negative or zero dirsize disappeared.
Drop the dead code and unsign dirsize given that it can't be
negative anyways.

The motivation here is to eventually teach netisr and potentially
other networking subsystems a bit more about how RSS work queues / buckets
are configured so things have a hope of auto-configuring in the future.
* net/rss_config.[ch] takes care of the generic bits for doing
configuration, hash function selection, etc;
* topelitz.[ch] is now in net/ rather than netinet/;
* (and would be in libkern if it didn't directly include RSS_KEYSIZE;
that's a later thing to fix up.)
* netinet/in_rss.[ch] now just contains the IPv4 specific methods;
* and netinet/in6_rss.[ch] now just contains the IPv6 specific methods.
This should have no functional impact on anyone currently using
the RSS support.

This bug was triggered if ACPI advertises the presence of a C2 state
which we fail to parse via acpi_PkgGas due to our lack of support for
