* The RFC says (in section 10.1) that only when extbuf is not NULL,
extlen shall be checked, so don't perform this check when NULL is
passed.
* socklen_t is unsigned, so checking extlen for less than zero is
not needed.

Prior to this change the cached value of 'pm_eptgen' was tracked per-vcpu
and per-hostcpu. In the degenerate case where 'N' vcpus were sharing
a single hostcpu this could result in 'N - 1' unnecessary TLB invalidations.
Since an 'invept' invalidates mappings for all VPIDs the first 'invept'
is sufficient.
Fix this by moving the 'eptgen[MAXCPU]' array from 'vmxctx' to 'struct vmx'.
If it is known that an 'invept' is going to be done before entering the
guest then it is safe to skip the 'invvpid'. The stat VPU_INVVPID_SAVED
counts the number of 'invvpid' invalidations that were avoided because
they were subsumed by an 'invept'.

did this only with the inner loop for the token parsing, and not the
outer loop which was understandable enough when the extra layers of
looping went away...

This fixes the read of mkuzip(8) images with geom_uncompress(4).

the old way was to store pcpu in a register, and get curthread from pcpu,
which is not very atomic, and led to issues if the thread was migrated
to another core between the time we got the pcpu address and the time we
got curthread.
Instead, we now store curthread where pcpu used to be store, and we
calculate the pcpu address based on the cpu id.
map a fraction of the pages that were fetched by vm_pager_get_pages() from
secondary storage. Now, we map them all in order to avoid future soft
faults. This effect is most evident when a memory-mapped file is accessed
sequentially. Previously, there were 6 soft faults for every hard fault.
Now, these soft faults are eliminated.

to check the status property in their probe routines.
Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352. Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.
Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.
process "status" properties of OF nodes.
I've avoided adding new KOBJ methods here so that we don't have to modify
every ofw_bus in the tree. Since 100% of implementations of ofw_bus use
only ofw_bus_gen_*(), it might be worth garbage-collecting the other
methods as well.
