code. There are only a handful of MSRs common between the two so there isn't
too much duplicate functionality.
The VT-x code has the following types of MSRs:
- MSRs that are unconditionally saved/restored on every guest/host context
switch (e.g., MSR_GSBASE).
- MSRs that are restored to guest values on entry to vmx_run() and saved
before returning. This is an optimization for MSRs that are not used in
host kernel context (e.g., MSR_KGSBASE).
- MSRs that are emulated and every access by the guest causes a trap into
the hypervisor (e.g., MSR_IA32_MISC_ENABLE).

the minimum image size specified is always less than the maximum
image size. If makefs(1) is invoked specifying minimum image size,
but not maximum one, the program exits with an error. Example:
# sudo -E makefs -M 538968064 -B be /home/davide/disk.img $DESTDIR
makefs: `/home/davide/tftproot/mips' minsize of 538968064 rounded up
to ffs bsize of 8192 exceeds maxsize 0. Lower bsize, or round the
minimum and maximum sizes to bsize.
Assert then that minsize < maxsize iff maxsize is specified.
This change allows me to build MIPS images using makefs(1) and following
what specified in the wiki again.

reality. In particular, draw a connection between the auto ZFS script and
the auto UFS one, since they fulfill similar functions. I'm not sure the
auto ZFS code is actually experimental anymore, so it might be worth
changing that label still.
It allows to bypass range checks between UNMAP and READ/WRITE commands,
which may introduce additional delays while waiting for UNMAP parameters.
READ and WRITE commands are always processed in safe order since their
range checks are almost free.
many thanks for their continued support of FreeBSD.
While I'm there, also implement a new build knob, WITHOUT_HYPERV to
disable building and installing of the HyperV utilities when necessary.
The HyperV utilities are only built for i386 and amd64 targets.
This is a stable/10 candidate for inclusion with 10.1-RELEASE.

NetBSD's virtio-net implementation doesn't negotiate
the merged rx-buffers feature. To support this, check
to see if the feature was negotiated, and then adjust
the operation of the receive path accordingly by using
a larger iovec, and a smaller rx header.
In addition, ignore writes to the (read-only) status byte.
Tested with NetBSD/amd64 5.2.2, 6.1.4 and 7-beta.

DIALOG_SELF_INITIALIZE to NULL, preventing f_dialog_init() from being run
automaticaly when `dialog.subr' is included. Caused by sub-shell processing
of arguments inheriting prior value of $OPTIND, used by getopts. Solved by
unsetting OPTIND prior to [re-]processing of positional arguments.
While there, add a NO_WTHREAD_SAFETY flag that can be used to disable
this specific warning flag. Disable it for auditdistd. We can easily
patch up auditdistd to have the right annotations to build, but as
auditdistd is intended to be portable across other operating systems,
it's not worth the effort.

packets at all. Swapping byte order on SOCK_RAW was actually a bug, an
artifact from the BSD network stack, that used to convert a packet to
native byte order once it is received by kernel.
Other operating systems didn't follow this, and later other BSD
descendants fixed this, leaving us alone with the bug. Now it is
clear that we should fix the bug.
