o Declare the above in <machine/pmap.h>
o Move the vm.stats.vhpt.* sysctls to machdep.vhpt.*
o Create a tunable machdep.vhpt.log2size, with corresponding sysctl.
The tunable allows the user to specify the VHPT size from the loader.
o Don't keep track of the number of PTEs in the VHPT. Calculate the
population when necessary by iterating the buckets and summing up
the length of the buckets.
o Don't perform the tpa instruction with a bucket lock held. The
instruction can (theoretically) fault and locking is not needed.
return the correct bar size if we encountered a 64-bit BAR that had
its resources already assigned. If the resources weren't yet
assigned, we'd bogusly assume it was a 32-bit bar and return 1.
is never 0, so one cannot test for a NULL pointer after a physical
address is translated into a virtual pointer with said macro. Instead,
keep the physical address around and test it against 0. Note that
this obviously implies that a PTE can never be allocated at physical
address 0. This isn't exactly guaranteed, but hasn't been a problem
so far. We test the physical address against 0 for as long as the ia64
port exists...
Files used both "securelevel" and either "secure level" or
"security level"; all are now "security level".

remaining % arguments because the varargs are now out of sync and
there is a risk that we might for instance dereference an integer
in a %s argument.

link proctree and allproc to Giant since that order is already implicitly
enforced.
- Use a goto to handle the case where we want to enforce a reversal before
calling isitmydescendant() in witness_checkorder() so that the logic is
easier to follow and so that it is easier to add more forced-reversal
cases in the future.

mutex.
- Don't panic if a spin lock is held too long inside _mtx_lock_spin() if
panicstr is set (meaning that we are already in a panic). Just keep
spinning forever instead.
- If an interface's ifconfig_<ifn> is set, but empty, don't set it to
ifconfig_DEFAULT. This way interfaces can be disabled even in the
presence of ifconfig_DEFAULT.
- When listing interfaces and network_interfaces=auto, place lo0 first
if it's around.
