Allow the PIC's IMR register to be read before ICW initialisation.
As of git submit e179f6914152eca9, the Linux kernel does a simple
probe of the PIC by writing a pattern to the IMR and then reading it
back, prior to the init sequence of ICW words.
The bhyve PIC emulation wasn't allowing the IMR to be read until
the ICW sequence was complete. This limitation isn't required so
relax the test.
With this change, Linux kernels 3.15-rc2 and later won't hang
on boot when calibrating the local APIC.

rm -rf can fail sometimes with an error from fts_read. Make it
honor fflag to ignore fts_read errors, but stop deleting from
that directory because no further progress can be made.
When building a kernel with a high -j value on a high core count
machine, during the cleanobj phase we can wind up doing multiple
rm -rf at the same time for modules that have subdirectories. This
exposed this race (sometimes) as fts_read can return an error if
the directory is removed by another rm -rf. Since the intent of
the -f flag was to ignore errors, even if this was a bug in
fts_read, we should ignore the error like we've been instructed
to do.

Correct display of bhyve SMBIOS UUIDs with dmidecode by bumping the version.
The mixed little/big-endianness of SMBIOS UUIDs was clarified in v2.6
of the SMBIOS spec. dmidecode uses the reported version of SMBIOS to
determine the layout and what to byte-swap.
bhyve's SMBIOS reported as 2.4 though it implemented the 2.6-style of
memory layout. This resulted in dmidecode reporting a different
UUID than one passed in via the -U option.
Iterate through all the children instead of returning error when we hit
the first error. This makes the error message give more information
rather than just the first device that causes problem.
Illumos issue:
5118 When verifying or creating a storage pool, error messages only
show one device
When asked to find a hole, the DMU sees that there are no holes in the
object, and returns ESRCH. The ZPL interprets this as "no holes before
the end of the file", and therefore inserts the "virtual hole" at the
end of the file. Because DMU and ZPL have different ideas of where the
end of an object/file is, we will end up returning the end of file,
which is generally larger, instead of returning the end of object.
The fix is to handle the "virtual hole" in the DMU. If no hole is found,
the DMU will return a hole at the end of the file, rather than an error.
Illumos issue:
5139 SEEK_HOLE failed to report a hole at end of file

Make sure all memory updates are made visible before we let go

this.

vt(4): Rewrite history scrolling
It's now possible to scroll up the 500 hard-coded lines of history, not
just a fraction of them. For instance, one can reach the top of the boot
process.
Sometimes, when scrolling or when changing the screen size (by changing
the font or loading a KMS driver for instance), one could see the
history cycling (old content appeared below latest lines). This is
fixed.
Now, when the resolution changes are more lines can be shown, the
displayed area is adjusted so that, if the screen was filled with
content before, it's filled with content after as well: more history
is visible, instead of having blank lines below the previously visible
content.

Workaround for receiving Voice Calls using the E1750 dongle from
Huawei. It might appear as if the firmware is allocating memory blocks
according to the USB transfer size and if there is initially a lot of
data, like at the answering machine prompt, it simply dies without any
apparent reason. The simple workaround for this is to force a zero
length packet at hardware level after every 512 bytes of data. This
will force the other side to use smaller memory blocks aswell.
Be compatible with boot code that starts right after the disk label in
the second sector by only clearing the amount of bytes needed for the
disklabel in the second sector. Previously we were clearing exactly 1
sector worth of bytes and as such writing over boot code that may have
been there.
Since we do support more than 8 partitions, make sure to set all fields
in d_partitions. For the first 8 partitions this is unneeded, but for
partitioons 9 and up this compensates for the fact that we don't clear
an entire sector anymore.
Obviously, one cannot use more than 8 partitions when using boot code
that starts right after the disk label.
Relevant GRNs:
107879 - Employ unused bytes after the disklabel in the second sector.
189500 - Revert the part of change 107879 that employs the unused bytes
after the disklabel in the 2nd sector for boot code.
