- Remove .c files which duplicate entries in MISRCS.
- Use the same, less merge conflict prone style in all cases.
- Use MDSRCS for mips (.c and .S files both ended up in SRCS).
- Remove pointless sparc64 Makefile.inc.
- Remove uninformative foreign VCS ID entries.

For short transactions overhead of context switch can be too large.
Skipping it gives significant latency reduction. For large ones,
including multiple ZIOs, latency is less critical, while throughput
there may become limited by checksumming speed of single CPU core.
To get best of both cases, execute last ZIO directly from calling
thread context to save latency, while all others (if there are any)
enqueue to taskqueues in traditional way.

The loader assumes physical memory in [2MB, 2MB + EFI_STAGING_SIZE)
is Conventional Memory, but actually it may not, e.g. in the case
of Hyper-V Generation-2 VM (i.e. UEFI VM) running on Windows
Server 2012 R2 host, there is a BootServiceData memory block at
the address 47.449MB and the memory is not writable.
Without the patch, the loader will crash in efi_copy_finish():
see PR 211746.
The patch verifies the end of the staging area, and reduces its
size if necessary. This way, the loader will not try to write into
the BootServiceData memory any longer.
Thank Marcel Moolenaar for helping me on this issue!
The patch also allocates the staging area in the first 1GB memory.
See the comment in the patch for this.

- Replace the "following lines" with more terse phrases.
- Use .Lk for the mellanox URL.
- Reword the SUPPORT section so it's less wordy.
The DESCRIPTION section suggestions are still outstanding; improving
the section requires additional review to make sure the nuance/message
is correct per the original intent.

Elf_map_insert() needs to create mapping at the known fixed address.
Usage of vm_map_find() assumes, on the other hand, that any suitable
address space range above or equal the specified hint, is acceptable.
Due to operating on the fresh or cleared address space, vm_map_find()
usually creates mapping starting exactly at hint.
Switch to vm_map_insert() use to clearly request fixed mapping from
the VM.

vm_map_insert() failure, drop the vnode lock around the call to
vm_object_deallocate().
Since the deallocated object is the vm object of the vnode, we might
get the vnode lock recursion there. In fact, it is almost impossible
to make vm_map_insert() failing there on stock kernel.

Unclear how, but the locking routine for mutexes was using the *release*
barrier instead of acquire. This must have been either a copy-pasto or bad
completion.
Going through other uses of atomics shows no barriers in:
- upgrade routines (addressed in this patch)
- sections protected with turnstile locks - this should be fine as necessary
barriers are in the worst case provided by turnstile unlock
I would like to thank Mark Millard and andreast@ for reporting the problem and
testing previous patches before the issue got identified.

- Use SRCTOP-relative paths to other directories instead of
.CURDIR-relative ones. This simplifies pathing in make/displayed output.
- Also, use :H where possible/sensical to manipulate .CURDIR-relative
paths
- Remove superfluous bsd.own.mk .includes which are already handled via
src.opts.mk .includes
