r347241 introduced an ifname <-> kld mapping table, mostly so tun/tap/vmnet
can autoload the correct module on use. It also inadvertently made bogus
some previously valid uses of sizeof().
Revert back to ifkind on the stack for simplicity sake. This reduces the
diff from the previous version of ifmaybeload for easiser auditing.
Since the partition/slice names do vary in length, check the length
of the fixed part of the line against 3 * 8, if the lenth is less than
3 tab stops, print out extra tab.
use snprintf() instead of sprintf.

lookup KPI in ip_output() like it is already used in ip_forward().
However, when there is no PCB provided we can use fast KPI, gaining
performance advantage.
Typical case when ip_output() is called without a PCB pointer is a
sendto(2) on a not connected UDP socket. In practice DNS servers do
this.

- there is no need to take the process lock to iterate the thread
list after single-threading is enforced
- typically there are no mutexes to clean up (testable without taking
the global umtx lock)

* Make mmu_booke_sync_icache() use the DMAP on 64-bit prcoesses, no need to
map the page into the user's address space. This removes the
pvh_global_lock from the equation on 64-bit.
* Don't map the page with user-readability on 32-bit. I don't know what the
chance of a given user process being able to access the NULL page when
another process's page is added there, but it doesn't seem like a good
idea to map it to NULL with user read permissions.
* Only sync as much as we need to. There are only two significant places
where pmap_sync_icache is used: proc_rwmem(), and the SIGILL second-chance
for powerpc. The SIGILL second chance is likely the most common, and only
syncs 4 bytes, so avoid the other 127 loop iterations (4096 / 32 byte
cacheline) in __syncicache().
Reduce the surface area of the TLB locks. Unfortunately the same trick for
serializing the tlbie instruction on OEA64 cannot be used here to reduce the
scope of the tlbivax mutex to the tlbsync only, as the mutex also serializes
the TLB miss lock as a side effect, so contention on this lock may not be
reducible any further.

Grab device reserved physical memory regions from FDT using standard
"memory-region" property and use vmem(9) to allocate buffers from it.
The same vmem could be used by DMA engine drivers to allocate memory for
DMA descriptors.
This is required for platforms that provide uncached memory region
reserved exclusively for DMA operations.
o Change sleepable sx(9) lock type to non-sleepable mutex(9) since
network drivers usually hold mutex during DMA operations. So we don't
take sleepable lock after non-sleepable.

Mjg@ reports that RDSEED (r347239) causes a lot of logspam from this printf,
and I don't feel that it is especially useful (even ratelimited). There are
many other quality/quantity checks we're not performing on entropy sources;
lack of high frequency availability does not disqualify a good entropy
source.
There is some discussion in the linked Differential about what logging might
be appropriate and/or polling policy for slower TRNG sources. Please feel
free to chime in if you have opinions.

Present code uses lock-less accesses to the dump data to prevent top
level ioctls from blocking bottom-level call to dump. Unfortunately, this
depends on the type stability of the dump data structure, which makes it
non-functional during driver teardown.
Switch to the mutex locking scheme where top levels use the mutex in the
bound regions, while copyouts and drain for completion utilize condvars.
The mutex lifetime is guaranteed to be strictly larger than the time
interval where driver can initiate dump, and most of the control fields
of the old struct mlx5_dump_data are directly embedded into struct
mlx5_core_dev.
