As reported by a FreeNAS user (see https://redmine.ixsystems.com/issues/55728),
mountd does more calls to getnameinfo() than it needs to; this changes it to
only call it for the RPC calls it needs the name information for.

warrants me a repo access to the ports tree anymore. Move myself into alumni

This patch simply ensures that scn->scn_prefetch_queue is emptied
before the kernel module is unloaded and when scanning completes.

Specifically, assume that the device is present if evaluation of _STA
method fails.

Before r330957 we ignored any _STA evaluation failure (which was
performed by AcpiGetObjectInfo in ACPICA contrib code) for the purpose
of acpi_DeviceIsPresent and acpi_BatteryIsPresent.  ACPICA 20180313
removed evaluation of _STA from AcpiGetObjectInfo.  So, we added
evaluation of _STA to acpi_DeviceIsPresent and acpi_BatteryIsPresent.
One important difference is that the new code ignored a failure only if
_STA did not exist (AE_NOT_FOUND).  Any other kind of failure was
treated as a fatal failure.  Apparently, on some systems we can get
AE_NOT_EXIST when evaluating _STA.  And that error is not an evil twin
of AE_NOT_FOUND, despite a very similar name, but a distinct error
related to a missing handler for an ACPI operation region.

It's possible that for some people the problem was already fixed by
changes in ACPICA and/or in acpi_ec driver (or even in BIOS) that fixed
the AE_NOT_EXIST failure related to EC operation region.

This work is based on a great analysis by cem and an earlier patch by
Ali Abdallah <aliovx@gmail.com>.

The POWER9 does not recognize 'or 27,27,27' as a thread priority NOP.  On
earlier POWER architectures, this NOP would note to the processor to give up
resources if able, to improve performance of other threads.

All processors that support the thread priority NOPs recognize the
'or 31,31,31' NOP as very low priority, so use this to perform a similar
function, and not burn cycles on POWER9.

The jump slot is a function pointer, not a descriptor pointer, in ELFv2.  Just
write the pointer itself over, not the contents of the pointer, which would be
the first instruction of the function.

The 'interrupts' property is actually 2 words, not one, on macgpio child
nodes.  Open Firmware's getprop function might be returning the value
copied, not the total size of the property, but FDT's returns the total
size.  Prior to this patch, this would cause the SYS_RES_IRQ resource list
to not be populated when running with the 'usefdt' loader variable set, to
convert the OFW device tree to a FDT.  Since the property is always 2 words,
read both words, and ignore the second.
