502e440349 m_clrprotoflags() is designed to cleanup M_PROTO flags when mbufs cross
protocol and facility boundaries.  However, now it cleans up only the
first mbuf, while intent clearly means all mbufs in a possible chain.

70d099afe0 Fix build with recent binutils
Recent binutils considered the .gnu.warning.symbol section as a fatal error when
run with --fatal-warnings which makes any users of "insecure" functions from
libc failing to build with recent binutils.

Introduce a new macro: LD_FATAL_WARNINGS=no to run ld(1) with
--no-fatal-warnings for the users of "insecure" functions

3e834dd35d Always select the card before we do the 4.x specific stuff and
deselect it after setting the block size. This is a similar bug that
was fixed elsewhere, but not here. This makes sure that we leave the
card deselected at the end of the loop, and we don't send any commands
to the card without it selected.

b053814333 Allow ktr(4) tracing of all guest exceptions via the tunable
"hw.vmm.trace_guest_exceptions".  To enable this feature set the tunable
to "1" before loading vmm.ko.

Tracing the guest exceptions can be useful when debugging guest triple faults.

Note that there is a performance impact when exception tracing is enabled
since every exception will now trigger a VM-exit.

Also, handle machine check exceptions that happen during guest execution
by vectoring to the host's machine check handler via "int $18".

af3cafd76c Add a new loader(8) variable, twiddle_divisor, allowing control over the
output frequency of the "twiddle" IO progress indicator.  The default
value is 1.  For larger values N, the next stage of the animation is only
output on every Nth call to the output routine.  A sufficiently large N
effectively disables the animation completely.

7e654612dc Strip trailing / characters from paths in "not present" index entries, not
just "directory" entries.

Prior to this commit, if / was added as part of a security update (how? In
the most recent case, because lib32 was accidentally omitted and was then
re-added, and every installer distribution set gets its own paths) then
the code which was supposed to filter out updates to deleted parts of the
base system (if someone decides to delete / then we shouldn't re-create it
for them) would instead get confused and decided that while / should exist,
// should not exist and needs to be removed.

This fixes the bug which caused freebsd-update to want to delete / (which is
harmless, since `rm /` fails, but scary nonetheless).  A workaround is being
applied to the update bits in order to avoid triggering the bug on unpatched
systems.

7668336c8e Add a divisor parameter to twiddle() so that callers can request that output
only happen on every Nth call.  Update the existing twiddle() calls done in
various IO loops to roughly reflect the relative IO sizes.  That is, tftp
and nfs call twiddle() on every 1K block, ufs on every filesystem block,
so the network calls now use a much larger divisor than disk IO calls.

Also add a new twiddle_divisor() function that allows an application to set
a global divisor that is applied on top of the per-call divisors.  Nothing
calls this yet, but loader(8) will be using it to further throttle the
cursor for slow serial consoles.

6831cf6aa6 Fix panic when resizing ZFS zvol's
Resizing a ZFS ZVOL with debug enabled would result in a panic due to
recursion on dp_config_rwlock.

The upstream change "3464 zfs synctask code needs restructuring" changed
zvol_set_volsize to avoid the recursion on dp_config_rwlock, but this was
missed when originally merged in by r248571 due to significant differences
in our codebases in this area.

These changes also relied on bring in changes from upstream:
3557 dumpvp_size is not updated correctly when a dump zvol's size is
changed, which where also not present.

In order to help prevent future issues in this area a direct comparison
and diff minimisation from current upstream version (b515258) of zvol.c.

acb332a8a1 vt: register the memory regions used by the vt drivers
Current VT drivers don't register the memory regions they use with the
nexus. This patch makes vt_vga and vt_efifb register the memory regions they
use.

This is needed (at least) for Xen support, since the FreeBSD kernel will try
to use the holes in the memory map to map memory from other domains and
setup it's grant table.
