The GVT-d emulation tries to allocate some specific memory. It could
happen that this address doesn't exist. In that case, GVT-d will fall
back to allocate any address. Nevertheless, this only works if the e820
fails with an error instead of exiting on an assertion.

When performing an "upgrade" (moving between FreeBSD releases, as
opposed to "update" which merely applies security/errata updates
to the installed release) FreeBSD Update:
1. Generates a list of "files needing to be merged", namely those
files which don't match the version installed in the "old" release
and have paths matching the MergeChanges configuration directive
(by default, /boot/device.hints and everything under /etc/).
and later on,
2. Compares the currently-installed files to the versions in the
"new" release, removing index entries for files which "don't need
to be updated because they're not changing".
Unfortunately if a file falls into both of these categories -- that
is to say, if a file in /etc/ is the same as the version in the new
release and not the same as the version in the old release -- the
resulting "merge" step saw that the file was no longer listed as
being part of the new release, resulting in the file being deleted.
For the first 18 years of FreeBSD Update's existence, this never
happened, since $FreeBSD$ tags resulted in "new release" files
always being different from any files systems would already have
installed.
This commit fixes this behaviour by only placing a file into the
"files needing to be merged" list if it does not match the version
in the old release *or* the version in the new release.

This patch fixes virtual machine single stepping on VMX hosts.
Currently, when using bhyve's gdb stub, each attempt at single-stepping
a vCPU lands in a timer interrupt. The current single-stepping mechanism
uses the Monitor Trap Flag feature to cause VMEXIT after a single
instruction is executed. Unfortunately, the SDM states that MTF causes
VMEXITs for the next instruction that gets executed, which is often not
what the person using the debugger expects. [1]
This patch adds a new VM capability that masks interrupts on a vCPU by
blocking interrupt injection and modifies the gdb stub to use the newly
added capability while single-stepping a vCPU.

mfiutil(8) in theory can work on devices attached to mrsas(4) but
mrsas(4) is missing the FreeBSD mfi(4) ioctl support. Once that
support is added to mrsas(4) then mrsasutil(8) can manage mrsas(4)
attached devices. So this commit depends on that. When mrsasutil(8)
is run it automatically opens /dev/mrsas0 instead of /dev/mfi0.
Add -D <device> and -t <type> flag to optionally specify mrsas or mfi to
work with the existing -u <unit>. Device is the device node with or

There are some use cases where bhyve has to prepare some special memory
regions. E.g. GPU passthrough for Intel integrated graphic devices needs
to reserve some memory for the graphic device. So, bhyve has to inform
the guest about those memory regions. This information can be passed by
the qemu fwcfg interface. As qemu creates an E820 table, we can reuse
the existing fwcfg item "etc/e820".
This commit is the first one of a series. It only adds a basic
implementation for the creation of the E820 table. Some subsequent
commits will add more items to the E820 table and register it as fwcfg
item.

The hypervisor is aware of all system properties. For the guest bios
it's hard and complex to detect all system properties. For that reason,
it would be better if the hypervisor creates acpi tables instead of the
guest. Therefore, the hypervisor has to send the acpi tables to the
guest. At the moment, bhyve just copies the acpi tables into the guest
memory. This approach has some restrictions. You have to keep sure that
the guest doesn't overwrite them accidentally. Additionally, the size of
acpi tables is limited.
Providing a plain copy of all acpi tables by fwcfg isn't possible. Acpi
tables have to point to each other. So, if the guest copies the acpi
tables into memory by it's own, it has to patch the tables. Due to
different layouts for different acpi tables, there's no generic way to
do that. For that reason, qemu created a table loader interface. It
contains commands for the guest for loading specific blobs into guest
memory and patching those blobs.
This commit adds a qemu_loader class which handles the creation of qemu
loader commands. At the moment, the WRITE_POINTER command isn't
implement. It won't be required by bhyve's acpi table generation yet.
