Change 294329 removed the ability to build ZFS pools that are backed by
zvols, because having that ability (even if it's not used) leads to
deadlocks. By popular demand, I'm adding an off-by-default sysctl to
reenable that ability.

wraps sendmsg(2) and recvmsg(2) into batch send and receive operation.
The goal of this implementation is only to provide API compatibility
with Linux.
The cancellation behaviour of the functions is not quite right, but
due to relative rare use of cancellation it is considered acceptable
comparing with the complexity of the correct implementation. If
functions are reimplemented as syscalls, the fix would come almost
trivial. The direct use of the syscall trampolines instead of libc
wrappers for sendmsg(2) and recvmsg(2) is to avoid data loss on
cancellation.

diff(1) output between two files in "new_only"-mode. Otherwise,
with the default of using unified format a remnant of the header
in the output is the result. This is especially irritating when
the two files differ but the second one is empty, amounting to the
vestige of the header being the only readout.

The NVMe specification does not define a maximum or optimal delete
size, so technically max delete size is min(full size of namespace,
2^32 - 1 LBAs). A single delete operation for a multi-TB NVMe
namespace though may take much longer to complete than the nvme(4)
I/O timeout period. So choose a sensible default here that is still
suitably large to minimize the number of overall delete operations.
This also fixes possible uint32_t overflow on initial TRIM operation
for zpool create operations for NVMe namespaces with >4G LBAs.

Some firmware revisions provide different DTB tree that include

This commit adds support for 2 new buses:
- MRML bridge (PCIB subordinate)
- MDIO nexus (MRML subordinate)

Use driver settable callbacks for handling of:
- core post reset
- reading actual port speed
Typically, OTG enabled EHCI cores wants setting of USBMODE register,
but this register is not defined in EHCI specification and different
cores can have it on different offset.
Also, for cores with TT extension, actual port speed must be determinable.
But again, EHCI specification not covers this so this patch provides
function for two most common variant of speed bits layout.

Use per-CPU structure to store HW watchpoints registers state
for each CPU present in the system. Those registers will be restored
upon wake up from the STOP state if requested by the debug_monitor
code. The method is similar to the one introduced to AMD64.
We store all possible 16 registers for HW watchpoints
(maximum allowed by the architecture).
HW breakpoints are not maintained since they are used for single
