case another thread has had the VFP unit enabled and will have its state
in the VFP registers along with it stored in memory. As such we don't need
to store the state, but do need to zero the fpcurthread pointer to stop
the VFP driver from using the enable fast path.

Some drm2 drivers will set PG_FICTITIOUS in physical pages in order to
satisfy the OBJT_MGTDEVICE object interface, so a scan may encounter
fictitous pages. For now, allow for this possibility; such pages will be
skipped later in the scan since they are wired.

The vast majority of pmap_kextract() calls are looking for a physical memory
address, not a device address. By checking the page table first this saves
the formerly inevitable 64 (on e500mc and derivatives) iteration loop
through TLB1 in the most common cases.
Benchmarking this on the P5020 (e5500 core) yields a 300% throughput
improvement on dtsec(4) (115Mbit/s -> 460Mbit/s) measured with iperf.
Benchmarked on the P1022 (e500v2 core, 16 TLB1 entries) yields a 50%
throughput improvement on tsec(4) (~93Mbit/s -> 165Mbit/s) measured with
iperf.

This replaces a partial workaround introduced in r305527 that was
incompatible with nested INTRNG interrupt controllers if not also using
FDT.
On non-FDT MIPS INTRNG targets, we now preemptively produce a set of fixed
mappings for the MIPS IRQ range during nexus attach. On FDT targets,
OFW_BUS_MAP_INTR() remains responsible for mapping the MIPS IRQs.

When called with an absolute pathname, periodic should attempt to execute
every script in that directory. If the directory does not exist, it should
print an error and exit 1. Due to a copy/paste mistake in r231568, it exits
0 in that case.

This, along with a change to share/mk/bsd.cpu.mk to include -mno-avx2

Msdosfs allows setting READONLY by clearing the owner write bit of the file

functional change.)
In msdosfs_getattr, intuitively reflect that READONLY attribute to userspace

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of

XX_VirtToPhys(), by way of pmap_kextract(), is an expensive operation.
Profiling via dtrace during a series of iperf tests I found 16111 / 30432
stack frames were located in mmu_booke_kextract(), so eliminating this
expensive call should improve performance slightly. XX_PhysToVirt() is not
as expensive, but redundant calls in this context is wasteful.
We currently support the a83t's r_intc in a somewhat hack-ish way; our .dts
describes it as nmi_intc, and uses a subset of the actual register space to
make it line up with a20/a31 nmi offsets.
This breaks with the recent 4.14 update describing r_intc using the full
register space, so update aw_nmi to use the correct register offsets with
the right compat data in a way that doesn't break our current dts with
nmi_intc or upstream with r_intc described.
