- Characters in range 0x01-0x1f except '\t', '\n', and '\r' are replaced
with '?'. Those characters are disallowed in XML.
- '&', '<', '>', '\'', '"' and characters in range 0x7f-0xff are
replaced with XML numeric character reference.
If the kern.geom.confxml sysctl provides invalid XML, libgeom
geom_xml2tree() fails and utilities using it do not work. Unsafe
characters are common in msdosfs and cd9660 labels.

generally protected by the VM page queue mutex. Instead of extending the
table lock to cover the PVO heads, add some asserts that the page queue
mutex is in fact held. This fixes several LORs and possible deadlocks.
This also adds an optimization to moea64_kextract() useful for
direct-mapped quantities, like UMA buffers. Being able to use this from
inside UMA removes an additional LOR.

Use this as the preferred timecounter for the SWARM kernels.
The CP0 COUNT register is unusable as the timecounter on SMP platforms because
the COUNT registers on different CPUs are not guaranteed to be in sync.

Some 32-bit arithmetic operations (e.g. subu) have unpredicatable results

mapped kseg0 region.
The basic idea is to use KVA from the kseg2 region for mapping page
table pages that lie beyond the direct mapped region.
The TLB miss handler can now recursively fault into the TLB invalid
handler if it dereferences a kseg2 page table page address that is not
in the TLB.

The order of operations is the following:
1. Try to open vdev by remembered path and guid.
2. If 1 failed, try to find vdev which guid matches and ignore the path.
3. If 2 failed this means either that the vdev we're looking for is gone
or that pool is being created and vdev doesn't contain proper guid yet.
To be able to handle pool creation we open vdev by path anyway.
Because of 3 it is possible that we open wrong vdev on import which can lead to
confusions.
The solution for this is to check spa_load_state. On pool creation it will be
equal to SPA_LOAD_NONE and we can open vdev only by path immediately and if it
is not equal to SPA_LOAD_NONE we first open by path+guid and when that fails,
we open by guid. We no longer open wrong vdev on import.

that provides the allocated and setup eventhandler entry.
Add a new wrapper for VIMAGE that allocates extra space to hold the
callback function and argument in addition to an extra wrapper function.
While the wrapper function goes as normal callback function the
argument points to the extra space allocated holding the original func
and arg that the wrapper function can then call.
Provide an iterator function for the virtual network stack (vnet) that
will call the callback function for each network stack.
Provide a new set of macros for VNET that in the non-VIMAGE case will
just call eventhandler_register() while in the VIMAGE case it will use
vimage_eventhandler_register() passing in the extra iterator function
but will only register once rather than per-vnet.
We need a special macro in case we are interested in the tag returned
as we must check for curvnet and can neither simply assign the
return value, nor not change it in the non-vnet0 case without that.
