Avoid showing stale errors when nmount(2) fails.
Sometimes nmount(2) will fail without setting errmsg. The previous (ignored)
error would then be shown as the reason for the failed call if the next
nmount(2) also fails without [ENOENT,ENOTSUP].
An example is when there is a tmpfs mounted with -o size. vfs_filteropt() adds
'size' as an error in errmsg due to 'size' not being in tmpfs_updateopts. Then
tmpfs_mount returns [ENOTSUP] from nmount(2), which is then ignored. The next
call may race with an unmount causing an invalid [EINVAL] that then does log an
error, with the tmpfs errmsg.
The race itself is a separate issue to fix as it is expected to have an
[ENOENT] returned instead.
In this example the mount being shown is actually nullfs, not tmpfs that the
error is from.

Revert r267233 for now. PIE support needs to be reworked.
1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
where it never would work anyhow, such as csu or loader. This suggests
there may be better ways of adding support to the tree. Many of these
cases can be fixed such that -fPIE will work but there is really no
reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
really building libraries but have been using bsd.prog.mk because the code
is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
been needed.
We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

For vendors like Juniper, extensibility for sockets is important. A
good example is socket options that aren't necessarily generic. To
this end, OSD is added to the socket structure and hooks are defined
for key operations on sockets. These are:
o soalloc() and sodealloc()
o Get and set socket options
o Socket related kevent filters.
One aspect about hhook that appears to be not fully baked is the return
semantics (the return value from the hook is ignored in hhook_run_hooks()
at the time of commit). To support return values, the socket_hhook_data
structure contains a 'status' field to hold return values.

Import the tools used to convert the keymap files from SYSCONS (in locale
dependent encoding) to NEWCONS (Unicode).
The file "LANG.map" is used to convert INDEX.keymaps. It has 3 columns:
- the language ID as used in the source file
- the language ID to be used in the generated file (e.g. "iw" -> "he")
- the encoding of the menu texts for this language
The conversion result is written to STDOUT.
The file "KBDFILES.map" is used to batch convert keymap files. It's
columns are:
- the encoding used for the keymap sounce file
- the name of the source file
- the name of the generated file
The output files are created in the TEMP sub-directory of the vt keymap
directory, in order to preserve (possibly uncommitted) keymap files in
/usr/src/share/vt/keymaps.
The convert-keymap.pl script can be directly executed by passing the
source file name and the encoding on the command line. It writes to
STDOUT and generates hex Unicode codepoints by default. (This can be
changed to decimal in the script.)
While written for the one-time conversion of the SYSCONS keymaps into
the format required for NEWCONS, I think these tools may be useful for
easy conversion of possible further SYSCONS keymap files, that have not
been committed to the source tree.

Attempt at converting the SYSCONS keymaps to Unicode for use with NEWCONS.
I have spent many hours comparing source and destination formats, and hope
to have caught the most severe conversion errors.
Files were converted with a Perl script which I'll shortly commit to the
tools directory. This script is a much enhanced version of the one
provided by ray@ and is expected to support the full kbdmap(5) syntax.
The naming convention used is:
<2-letter country code>.<variant>.kbd
Only if there are multiple layouts for different languages:
<2-letter country code>-<2-letter language code>.<variant>.kbd
In nearly all cases, the keyboards are country specific, only. Currently
there is only one case where the language was added ("ch-fr.kbd" for
the Swiss-French keyboard layout).
I choose to write Unicode character codes as hex numbers. While this
increases the diff to the SYSCONS keymap files for the trivial cases
(conversion from ISO8859-1), it really helps to verify the more complex
cases against a Unicode table (which is indexed by hex numbers).
This commit does not cover all files that have been converted, since I
need to sort out which ones to use, if there were several with different
source encodings to choose from.
Review and test of the keymap files is highly desirable before 10.1 is
released. I'd also appreciate educated opinions regarding the optimum
variant (to be made available as the default for each language).
Since there are no NEWCONS keymaps in 10-STABLE, I plan to MFC after

Update to the current version of netmap.
Mostly bugfixes or features developed in the past 6 months,
so this is a 10.1 candidate.
Basically no user API changes (some bugfixes in sys/net/netmap_user.h).
In detail:
1. netmap support for virtio-net, including in netmap mode.
Under bhyve and with a netmap backend [2] we reach over 1Mpps
with standard APIs (e.g. libpcap), and 5-8 Mpps in netmap mode.
2. (kernel) add support for multiple memory allocators, so we can
better partition physical and virtual interfaces giving access
to separate users. The most visible effect is one additional
argument to the various kernel functions to compute buffer
addresses. All netmap-supported drivers are affected, but changes
are mechanical and trivial
3. (kernel) simplify the prototype for *txsync() and *rxsync()
driver methods. All netmap drivers affected, changes mostly mechanical.
4. add support for netmap-monitor ports. Think of it as a mirroring
port on a physical switch: a netmap monitor port replicates traffic
present on the main port. Restrictions apply. Drive carefully.
5. if_lem.c: support for various paravirtualization features,
experimental and disabled by default.
Most of these are described in our ANCS'13 paper [1].
Paravirtualized support in netmap mode is new, and beats the
numbers in the paper by a large factor (under qemu-kvm,
we measured gues-host throughput up to 10-12 Mpps).
A lot of refactoring and additional documentation in the files
in sys/dev/netmap, but apart from #2 and #3 above, almost nothing
of this stuff is visible to other kernel parts.
Example programs in tools/tools/netmap have been updated with bugfixes
and to support more of the existing features.
This is meant to go into 10.1 so we plan an MFC before the Aug.22 deadline.
A lot of this code has been contributed by my colleagues at UNIPI,
including Giuseppe Lettieri, Vincenzo Maffione, Stefano Garzarella.

Namely, the fast path is taken when the faulted page already exists

For technical reasons, fast path is avoided when the fault is the
first write on the vnode object, or when the fault is for wiring or
debugger read or write.
On the fast path, pmap_enter(9) is passed the PMAP_ENTER_NOSLEEP flag,
