Remove code that supported pre-2011 kernels. CTLTYPE_S64 was defined
in rev 217616. All supported branches have it, so remove its compat
definition as OBE.
I noticed after the review that these shouldn't be static. Remove the
'static' from them, otherwise concurrent calls to warn* might see a
similar but to the original.
When warn() family of functions is being used after err_set_file() has
been set to, for example, /dev/null, errno is being clobbered,
rendering it unreliable after, for example, procstat_getpathname()
when it is supposed to emit a warning. Then the errno is changed to
Inappropriate ioctl for device, destroying the original value (via
calls to fprintf()functions).

PCIe allows for MSI-X BAR to be either dedicated, or MSI-X Table may
be co-located in some functional BAR. In the later case xhci(4) is
unable to allocate active resource for the table because BAR is
already activated.
Handle it by checking for this special case, and not try to alloc
resource if MSI-X BAR is IO.

GNU and Oracle libelf implementations added support for section
compression, intended to reduce the size of DWARF debug info (which
might be an order of magnitude larger than the code).
There are two compressed ELF section formats:
1. Old GNU - sections are renmaed to start with 'z'. Section contains
a magic number, uncompressed size, and compressed data.
2. Oracle and New GNU - compressed sections use the SHF_COMPRESSED flag.
The compression header contains the compression type, uncompressed
size, and uncompressed alignment.
The second style is preferred and this change implements only that one.

The previous scheme for calculating the total size was doing sizeof
on the struct and then adding the wanted space for the buffer.
nc_name is at offset 58 while sizeof(struct namecache) is 64.
With CACHE_PATH_CUTOFF of 39 bytes and 1 byte of padding we were
allocating 104 bytes for the entry and never accounting for the 6
byte padding, wasting that space.
It no longer protects any of tested fields, keeping all the checks racy.
While here make vtryrecycle drop the vnode on its own. Avoids an additional
lock trip.
The NTB hardware starting with Skylake has some changes to the register

Calendar files in /usr/lcoal/share/calendar take precedence over files in
the base system. They can be provided by a port or package, but since such
a port has not been committed, yet, no specific port name is suggested.
In fact, multiple ports could exist (e.g. per locale) without conflicting
with each other.
Calendar files in LOCALBASE override similarily named ones in the base
system. This could easily be changed if the base system calendars should
have precedence, but it could lead to a violation of POLA since then the
port's files were ignored unless those in base have been deleted.
There was no definition of _PATH_LOCALBASE in paths.h, but verbatim uses
of /usr/local existed for _PATH_DEFPATH. Use _PATH_LOCALBASE here to ease
a consistent modification of this prefix.

In certain edge cases, the NIC might have only received a partial TLS
record which it needs to return to the driver. For example, if the
local socket was closed while data was still in flight, a partial TLS
record might be pending when the connection is closed. Receiving a
RST in the middle of a TLS record is another example. When this
happens, the firmware returns the the partial TLS record as plain TCP
data via CPL_RX_DATA. Handle these requests by returning an error to
OpenSSL (via so_error for KTLS or via an error TLS record header for
the older Chelsio OpenSSL interface).

We are using asize property from pool label and we do not depend
on partition data to find last two pool labels and to validate LBA for disk IO.
This does allow us to re-enable support for partitionless disk setups.
mkdir -p /foo/bar/baz will mkdir each path component and ignore EEXIST.
The NOCACHE lookup will make the namecache unnecessarily evict the existing entry,
and then fallback to the fs lookup routine eventually leading namei to return an
error as the directory is already there.
For invocations like mkdir -p /usr/obj/usr/src/sys/GENERIC/modules this triggers
fallbacks to the slowpath for concurrently executing lookups.
