true. This enables the discovery and probing of other LUNs the
target has to offer.
Add uk* to amd64 RAMDISK_CD so such devices are configured.
Allows bsd.rd as well as bsd[.mp] to boot on Oracle Cloud amd64
instances.
Issue reported by Ryan Kavanagh and Scott Nicholas via bugs@.
Original diff and much subsequent testing by Scott. Thanks!

If a host suspends or hibernates, a task in the middle of using
vcpu state may be rescheduled to another cpu. This is primarily a
problem for Intel hosts as vcpu state is kept local to the physical
cpu and must be flushed back to physical memory before another cpu
can issue certain vmx instructions.
This change ensures no tasks are actively using the vmm device,
flushes all vcpu state (if Intel hardware), and turns off virtualization
mode on the host cpus. Upon wakeup, we reverse the process.

an FDT overflow if the original FDT doesn't have enough space for the
additional properties that we add to it in our bootloader.

memory beyond the actual FDT data structure when adding information to the
device tree. This is especially problematic on ACPI systems where we add
lots of information to the device tree based on ACPI tables. Fix the FDT
code to never write beyond the end of the data structure and panic if we
run out of free space. Raise the amount of free space frm 4K to 16K for
the proto-FDT we use on ACPI systems. Bump the version number of the
arm64 bootloader.

has a method to read the counter that forms the base of the RTC. This seems
to be the preferred way to access the RTC going forward. The RTC offset is
still stored in the SPMI PMU, but we can use the nvmem interface to read
and write that. This makes the RTC work on systems with the M1 Pro/Max SoC.
Sprinkle some #ifdef SMALL_KERNEL around and enable the driver on RAMDISK
kernels.

This version appears to be more scalable (supports more cores, more
interrupts) but is still fairly similar to the previous generation so
it makes sense for them to share a driver. One major difference is that
it seems that the new interrupt controller no longer has the ability to
have external interrupts target specific CPU cores. Instead it delivers
them to whichever core is willing to handle the interrupt. Since this
currently isn't compatible with what OpenBSD wants we disable the
delivery of external interrupts to the secondary cores by setting some
bits in an implementation-defined system register.
This makes OpenBSD run on M1 Pro/Max machines.

Pad trapframe and switchframe structs so that their size is a multiple
of 16 bytes. This makes context switching and exception handlers keep
kernel stack properly aligned.
