When merging docsinstall and zfsboot updates to stable/9 it was discovered
that the slightly older dialog(1) requires --separate-output when using the
--checklist widget to force response to produce unquoted values (whereas in
stable/10 --checklist widget without --separate-output will only quote the
checklist labels in the response if the label is multi-word (contains any
whitespace).
Since these enhancements (see revisions 263956 and 264437) were developed
originally on 10, the --separate-output option was omitted. When merged to
stable/9, we (Allan Jude) and I found during testing that the "always-
quoting" of the response was causing things like struct interpolation to
fail (`f_struct device_$dev' would produce `f_struct device_\"da0\"' for
example -- literal quotes inherited from dialog(1) --checklist response).
To see the behavior, execute the following on stable/9 versus stable/10:
dialog --checklist disks: 0 0 0 da0 "" off da1 "" off
Check both items and hit enter. On stable/10, the response is:
da0 da1
On stable/9 the response is:
"da0" "da1"
If you use the --separate-output option, the response is the same for both:
da0
da1
So applying --separate-output on every platform until either one of two
things occurs 1) dialog(1,3) gets synchronized between stable/9, higher or
2) we drop support for stable/9.
MFC 258860,260167,260238,260397:
- Restructure the VMX code to enter and exit the guest. In large part this
change hides the setjmp/longjmp semantics of VM enter/exit.
vmx_enter_guest() is used to enter guest context and vmx_exit_guest() is
used to transition back into host context.
Fix a longstanding race where a vcpu interrupt notification might be
ignored if it happens after vmx_inject_interrupts() but before host
interrupts are disabled in vmx_resume/vmx_launch. We now call
vmx_inject_interrupts() with host interrupts disabled to prevent this.
- The 'protection' field in the VM exit collateral for the PAGING exit is
not used - get rid of it.
Implement GNU's extension of 'status' operand. The GNU syntax is
borrowed where syntax status=noxfer means no transfer statistics
and status=none means no status information at all.
This feature is useful because the statistics information can
sometimes be annoying, and redirecting stderr to /dev/null would
mean error messages also gets silenced.

MFC r264295:
Remove support of LUN-based CD changers from cd(4) driver.
This code was heavily broken few months ago during CAM locking changes.
Fixing it would require almost complete rewrite. Since there are no
known devices on market using this interface younger then ~15 years, and
they are CD, not even DVD, I don't see much reason to rewrite it.
This change does not mean those devices won't work. They will just work
slower due to inefficient disks load/unload schedule if several LUNs
accessed same time.
- In the libiconv module for ISO 2022 restore the original order of the

Add a new sysctl, dev.cxgbe.N.rsrv_noflow, and a companion tunable,
hw.cxgbe.rsrv_noflow. When set, queue 0 of the port is reserved for
TX packets without a flowid. The hash value of packets with a flowid
is bumped up by 1. The intent is to provide a private queue for
link-level packets like LACP that is unlikely to overflow or suffer
deep queue latency.
- If we fail to do a non-blocking acquire of a buf lock while doing a
waiting sync pass we need to do a blocking acquire and restart.
Another thread, typically the buf daemon, may have this buf locked and
if we don't wait we can fail to sync the file. This lead to a great
variety of softdep panics because we rely on all dependencies being
flushed before proceeding in several cases.
- Gracefully handle truncation failures when trying to shrink directories.
This could cause dirhash panics since the dirhash state would be
successfully truncated while the directory was not.

MFC r264343:
Add SRC_UPDATE_SKIP, DOC_UPDATE_SKIP, and PORTS_UPDATE_SKIP
variables. These are intended to allow bypassing the
'svn co /usr/{src,doc,ports}' step in the chroot when the
tree exists from external means.
The use case here is that /usr/src, /usr/doc, and /usr/ports
in the chroot exist as result of zfs dataset clones, so it
is possible (and happens quite often) that the included
distributions may not be consistent. (This is not the case
for -RELEASE builds, but does happen for snapshot builds.)
Loosen the processing of *_IF_aliasN vars to be less strict. Previously,
the first alias had to be _alias0 and processing stopped at the first non-
defined variable (preventing gaps). Allowing gaps gives the administrator
the ability to group aliases in an adhoc manner and also lifts the
requirement to renumber aliases simply to comment-out an existing one.
Aliases are processed in numerical ascending order.
NB: Also Patches mdconfig{,2} rc(8) boot scripts to loosen the numbering
scheme for mdconfig_mdN settings to be less strict in the same manner.

Fix the resource information for the i2s-a node on certain G5 PowerMacs.
This is the first step needed to get the snapper codec working on those

The second step is to enable the corresponding I2S device and its clock.

and a PowerMac9,1 with a Shasta based macio.
The PowerMac7,2/7,3 with a K2 based macio can now also play sound.
- if TARGET_ARCH is not defined and XDEV_ARCH is defined then early define
TARGET_ARCH to the valud of XDEV_ARCH: This allow the xdev-build target
to be able to correctly chose the compiler it needs to build
- Allow overwriting XDTP to allow a user to not chose where the xdev env will
live in
- Fix build for gcc only xdev (like ia64) by providing the proper -B to the
toolchain and not relying on gcc being installed already in base
- Fix TOOLS_PREFIX so the generated toolchain has the right default sysroot when
installed intead of getting the DESTDIR one
- Fix supporting DESTDIR
- Also overwrite CXX (needed for cross building c++ libraries with clang) and
CPP (needed to cross build some libraries when gcc is the target default
compiler but gcc is not installed on the building host)
- Prevent XDTP from being a relative path:
XDTP is used as the default SYSROOT for clang and thus should be an absolute path.
- Respect default CC

Fix kern/187712: config(8) does not respect KERNCONFDIR.
The impact of this bug is that you cannot build a kernel if both of the
following are true:
1) The kernel config file is in a non-default location
2) The kernel config file uses the "include" statement from config(5).
usr.sbin/config/main.c
usr.sbin/config/config.8
usr.sbin/config/config.h
usr.sbin/config/lang.l
Added a "-I path" option to config(8). By analogy to cc(1), it adds
an extra path in which the "include" statement will search for
files.
Makefile.inc1
Pass "-I ${KERNCONFDIR}" to config(8).

Add a SUBDIR_PARALLEL option to bsd.subdir.mk, to allow make to process
all the SUBDIR entries in parallel, instead of serially. Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.
This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.
I tested this on a 24-core machine, with make -j48 buildworld (N = 6):
before stddev after stddev
======= ====== ======= ======
real time 1741.1 16.5 959.8 2.7
user time 12468.7 16.4 14393.0 16.8
sys time 1825.0 54.8 2110.6 22.8
(user+sys)/real 8.2 17.1
E.g. the build was approximately 45% faster in real time. On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive. But at least you can now almost max out a machine with
buildworld!

Enable parallel building for gnu/usr.bin and usr.bin/clang too.
login: Clean up PAM and audit, then exit, on SIGHUP and SIGTERM.
This avoids leaving stale entries in utmpx after the connection is closed on
an open login session. It also allows a clean way (SIGTERM) to forcibly
terminate a user's terminal session.
This does not affect the situation for "hung" processes after the connection
is closed. The foreground process group receives SIGHUP and the tty becomes
inaccessible.
Also replace all use of the obsolete signal() function with sigaction() (not
only the part where it is actually required: SIGHUP and SIGTERM must mask
the other as well when caught).
