The switch to lualoader creates a problem with userboot: the host is
inclined to build userboot with Lua, but the host userboot's interpreter
must match what's available on the guest. For almost all FreeBSD guests in
the wild, Lua is not yet available and a Lua-based userboot will fail.
This revision updates userboot protocol to version 5, which adds a
swap_interpreter callback to request a different interpreter, and tries to
determine the proper interpreter to be used based on how the guest
/boot/loader is compiled. This is still a bit of a guess, but it's likely
the best possible guess we can make in order to get it right. The
interpreter is now embedded in the resulting executable, so we can open
/boot/loader on the guest and hunt that down to derive the interpreter it
was built with.
Using -l with bhyveload will not allow an intepreter swap, even if the
loader specified happens to be a userboot with the wrong interpreter. We'll
simply complain about the mismatch and bail out.
For legacy guests without the interpreter marker, we assume they're 4th.
For new guests with the interpreter marker, we'll read it and swap over
to the proper interpreter if it doesn't match what the userboot we're using
was compiled with.
Both flavors of userboot are installed by default, userboot_4th.so and
userboot_lua.so. This fixes the build WITHOUT_FORTH as a coincidence, which
was broken by userboot being forced to 4th.

Some paths through be_exists will set the error state, others will not
There are multiple reasons that a call can fail, so clean it up a bit: all
paths now return an appropriate error code so the caller can attempt to
distinguish between a BE legitimately not existing and just having the wrong
mountpoint. The caller is expected to bubble the error through to the
internal error handler as needed.
This fixes some unfriendliness with bectl(8)'s activate subcommand, where
it might fail due to a bad mountpoint but the only message output is a
generic "failed to activate" message.

The PCIOCLISTVPD ioctl on /dev/pci is used to fetch a list of VPD
key-value pairs for a specific PCI function. It is used by
'pciconf -l -V'. The list is stored in a userland-supplied buffer as
an array of variable-length structures where the key and data length
are stored in a fixed-size header followed by the variable-length
value as a byte array. To facilitate walking this array in userland,
<sys/pciio.h> provides a PVE_NEXT() helper macro to return a pointer
to the next array element by reading the the length out of the current
header and using it to compute the address of the next header.
To simplify the implementation, the ioctl handler was also using
PVE_NEXT() when on the user address of the user buffer to compute the
user address of the next array element. However, the PVE_NEXT() macro
when used with a user address was reading the value's length by
indirecting the user pointer. The value was ready after the current
record had been copied out to the user buffer, so it appeared to work
on architectures where user addresses are directly dereferencable from
the kernel (all but powerpc and i386 after the 4:4 split). The recent
enablement of SMAP on amd64 caught this violation however. To fix,
add a variant of PVE_NEXT() for use in the ioctl handler that takes an
explicit value length.

lualoader has moved to a model where the user is expected to disable color
as desired, rather than disabling it automatically for serial boots, due to
more wide-spread support for color sequences.
In a similar vain, though also to reduce special cases, lualoader no
longer disables the beastie menu automatically for !x86. This was done in
Forth land with a different loader.rc that simply didn't invoke the menu
routines, thus wasn't necessary.
This set of changes puts release images back to how they would've been
experienced prior to the switch to Lua.

at the BUS_PASS_BUS pass.
Change the pass for the prcm driver to be at BUS_PASS_BUS so we will win

This introduce a problem as this driver needs the omap_scm one to be already
attached. omap_scm also attach at BUS_PASS_BUS but after the prcm one as it is

Previously, x86 used static ranges of IRQ values for different types
of I/O interrupts. Interrupt pins on I/O APICs and 8259A PICs used
IRQ values from 0 to 254. MSI interrupts used a compile-time-defined
range starting at 256, and Xen event channels used a
compile-time-defined range after MSI. Some recent systems have more
than 255 I/O APIC interrupt pins which resulted in those IRQ values
overflowing into the MSI range triggering an assertion failure.
Replace statically assigned ranges with dynamic ranges. Do a single
pass computing the sizes of the IRQ ranges (PICs, MSI, Xen) to
determine the total number of IRQs required. Allocate the interrupt
source and interrupt count arrays dynamically once this pass has
completed. To minimize runtime complexity these arrays are only sized
once during bootup. The PIC range is determined by the PICs present
in the system. The MSI and Xen ranges continue to use a fixed size,
though this does make it possible to turn the MSI range size into a
tunable in the future.
As a result, various places are updated to use dynamic limits instead
of constants. In addition, the vmstat(8) utility has been taught to
understand that some kernels may treat 'intrcnt' and 'intrnames' as
pointers rather than arrays when extracting interrupt stats from a
crashdump. This is determined by the presence (vs absence) of a
global 'nintrcnt' symbol.
This change reverts r189404 which worked around a buggy BIOS which
enumerated an I/O APIC twice (using the same memory mapped address for
both entries but using an IRQ base of 256 for one entry and a valid
IRQ base for the second entry). Making the "base" of MSI IRQ values
dynamic avoids the panic that r189404 worked around, and there may now
be valid I/O APICs with an IRQ base above 256 which this workaround
would incorrectly skip.
If in the future the issue reported in PR 130483 reoccurs, we will
have to add a pass over the I/O APIC entries in the MADT to detect
duplicates using the memory mapped address and use some strategy to
choose the "correct" one.
While here, reserve room in intrcnts for the Hyper-V counters.

At the time that mp_bootaddress() is called, phys_avail[] array does
not reflect some memory reservations already done, like kernel
placement. Recent changes to DMAP protection which make kernel text
read-only in DMAP revealed this, where on some machines AP boot page
tables selection appears to intersect with the kernel itself.
Fix this by checking the addresses selected using the same algorithm
as bootaddr_rwx(). Also, try to chomp pages for the page table not
only at the start of the contiguous range, but also at the end. This
should improve robustness when the only suitable range is already
consumed by the kernel.
