This amounts to a char ** since it is a char[8] *. Evil casts mostly
resolved the fact that what was actually passed in were plain char *.
Instead, change the DES functions to use 'unsigned char *' for keys
and for input and output buffers.

The following checks are now being enforced:
- bpbBytesPerSec: only accept 512, 1024, 2048 and 4096.
- bpbSecPerClust: only accept 1, 2, 4, 8, 16, 32, 64 and 128.
- bpbResSectors: require non-zero.
- bpbFATs: require non-zero.
- bpbSectors: require zero for FAT32.
- bpbFATsmall: require zero for FAT32.
- bpbHugeSectors: require non-zero for FAT32.
Bail out if the BPB contained values that do not meet these requirements.
We also require FATsecs * FATsecs to not overflow 32-bit unsigned
integer.
Check for backup boot block was removed because the checker does not take
corrective action, and msdosfs driver ignores it too.
The kernel thread stack zone performs first-touch allocations by
default, and must handle the case where the local memory domain
is empty. For most UMA zones this is handled in the keg layer,
but cache zones currently must implement a policy for this case.
Simply use a round-robin policy if UMA_ANYDOMAIN is passed.

The netmap_pt.c module has become obsolete after

Many arm kernel configs bogusly specified WERROR=-Werror. There's no
reason for this because the default is that and there's no reason to
override. These date from a time when we needed to add additional
warning->error suppression. They are obsolete and were cut and paste
propagated from file to file.
Comment out all the WERROR=.... lines in powerpc. They aren't bogus,
but were appropriate for the old defaults for gcc4.2.1. Now that we've
made the policy decision to suppress -Werror by default on these
platforms, it is appropriate to comment these out. People wishing to
fix these errors can still un-comment them out, or say WERROR=-Werror
on the command line.
Fix two instances (cut and paste propagation) of hard-coded -Werror
in x86 code. Replace with ${WERROR} instead. This is a no-op change
except for people who build WERROR=-Wno-error :).
This should fix tinderbox / CI breakage.
This patch fixes a bug that made the mixer command enter
an infinite loop when instructed to set the value of a device
to an empty string (e.g., `mixer vol ""`).
Additionally, some tests for mixer(8) are being added.

merged, we consider them twice, first not-merging a with its successor
b, and then not-merging b with its predecessor a. This change replaces
vm_map_simplify_entry with vm_map_try_merge_entries, which compares
two adjacent entries only, and uses it to avoid duplicated
merge-checks.

While it worked with the kenrel, it wasn't working with the loader.
It failed to handle dependencies correctly. The reason for that is
that we never created a nvme module with the DRIVER_MODULE, but
instead a nvme_pci and nvme_ahci module. Create a real nvme module
that nvd can be dependent on so it can import the nvme symbols it
needs from there.
Arguably, nvd should just be a simple child of nvme, but transitioning
to that (and winning that argument given why it was done this way) is
beyond the scope of this change.

All existing callers guarantee that the page does not have a
pre-existing dequeue pending. Thus, if the page is dequeued before
pqbatch_submit() acquires the page queue lock, we do not need to do
anything since vm_page_dequeue_complete() takes care of clearing all
page queue state flags for us.
With this change, vm_page_pqbatch_submit() has the nice property that it
does not directly modify any fields in the page structure.
