Doing this on physical hosts turns out to be problematic, e.g. see comment
24 and 28 in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211746.
To fix the real underlying issue correctly & thoroughly, IMO we need
a relocatable kernel, but that would require a lot of complicated long
term work: https://reviews.freebsd.org/D9686?id=25414#inline-56969
For now, let's only apply efi_verify_staging_size() to VMs running on
Hyper-V, and restore the old behavior on physical machines since that
has been working for people for a long period of time, though that's
potentially unsafe...

Leap-second smearing is an experimental option that may be specified in
ntp.conf(5) and the -x option on the command line to spread the effect
of a leap-second over an interval as specified by the leapsmearinterval
config file statement. Recommended values are between 7200 (2 hours) and
86400 (24 hours).
It is advised that leap-second smearing not be used for public NTP
servers (https://www.meinbergglobal.com/download/burnicki/Leap\
%20Second%20Smearing%20With%20NTP.pdf). It is also advised that NTP
clients not use a mix of NTP servers using leap-second smearing with
NTP servers not using leap-second smearing as that could cause
undefined client behaviour.
Leap-second smearing was committed to ports net/ntp and net/ntp-devel
by r426825 on 2016-11-22.

This commit implements the (mostly?) Linux compatible
efidp_format_device_path and efidp_parse_device_path APIs. These are
the only APIs exposed through this library. However, they are built on
code from Tianocore's EDK2 MdePkg. They are brought in as new files
here for reasons described in FreeBSD-update.
Symbol versioning will be introduced to control what's exported from
the EDK2 code.
Some structural changes may be necessary when we move to sharing with
sys/boot/efi.

- Note that -s applies to rule keyword, only, by adding usage text
specifically for the `rule` and `ruleset` keywords.
Don't go into any further detail in usage(..) -- it's best that one
reads the manpage to get a better idea of how things work as there are
a number of different option-specific keywords and arguments, as well
as some rule grammar.

Starting with rev 5 (which is inexplicably indicated by a version number
of '3' in the Peripheral ID register), the pl011 doubled the size of the
rx and tx fifos, to 32 bytes, so read the ID register and set the size
variables in the softc accordingly.
An interesting wrinkle in this otherwise-simple concept is that the
bcm2835 SoC, used in Raspberry Pi systems among others, has the rev 5
pl011 hardware, but somehow also has the older 16-byte fifos. We check
the FDT data to see if the hardware is part of a bcm283x system and use
the smaller size if so.
Thanks to jchandra@ for pointing out that newer hardware has bigger fifos.

It seems that in the case where arc_hdr_free_pdata() sees HDR_L2_WRITING() we
would fail to update the ARC space statistics.
In the normal case those statistics are updated in arc_free_data_buf(). But in
the arc_hdr_free_on_write() path we don't do that.

get_clones_stat() could be very slow if a snapshot has many (thousands) clones.
Clone names are added to an nvlist that's created with NV_UNIQUE_NAME.
So, each time a new name is appended to the list, the whole list is searched
linearly to see if that name is not already in the list. That results in the
quadratic complexity.
That should be easy to fix as we know in advance that we should not get any
duplicate names, so we can drop NV_UNIQUE_NAME when creating the list.
