Add support for experimental Rendition Verite 3D acceleration interface.
This allow userland process to load 3D firmware (like v2000gl.uc) and
execute it on the chip's RISC CPU. It also provides the necessary support
infrastructure like basic VRAM accounting and ability to feed commands
and data through DMA.
In conjuction with customized userland Mesa, this allows OpenGL 1.x
workloads to run accelerated on the Verite.
While here, add related debugging facilities.
/etc/rc.d/unbound: Fix order of migration and trust anchor setup.
Add some comments explaining the order, and make sure we propagate
various failures back to the caller.
Based on a patch by Erik LaBine.

t_signal_and_fpu: Fix XMM register trashing.
The units we read from memory into registers are 16 bytes (128 bits)
each, not 32 bytes (256 bits).
Fortunately, this mistake didn't prevent the test from generally
working: reading past the end of our stack frame will just give us
other garbage that is unlikely to coincide with the register content
that the interrupted code expects.

nvmm: Add support for extended CPU state (XSAVE) beyond x87/SSE.
New machine-dependent x86 vCPU configuration command
NVMM_VCPU_CONF_XCR0_MASK sets the vCPU's XCR0 mask, that is, the set
of XSAVE features that the guest sees as supported in the vCPU. This
command is advertised by the new machine capability
NVMM_CAP_ARCH_VCPU_CONF_XCR0_MASK. (Changing the XCR0 mask after the
guest has begun execution will clear all extended CPU state for now;
it is unlikely that hypervisor software will do this anyway.)
This change doesn't expose the XSAVE area to userland in the comm
page -- there are already machine-independent members in struct
nvmm_comm_page at fixed offsets past the machine-dependent state so
we can't just extend struct nvmm_vcpu_state without breaking the ABI.
And the XSAVE area may exceed a page, but the address space for the
virtual machine uvm object packs comm areas in consecutive pages, so
we can't put it in the comm page at all without breaking the ABI
another way.

meta_ignore use :N with .MAKE.META.IGNORE_PATTERNS
By using :N .MAKE.META.IGNORE_PATTERNS is just a special case
of .MAKE.META.IGNORE_FILTER and processed the same way.
Now that bad144 handling is isolated to the places that care about it,
garbage-collect it from all of the various machine-dependent files that
have been cargo-culting it around needlessly for 20+ years.
Version bump to 11.99.7 because this changes the size of struct cpu_disklabel
on some platforms, and that structure is exposed in the module ABI.
Apply changes between 2026b and 2026c
Release 2026c - 2026-07-08 10:23:58 -0700
Briefly:
Alberta moved to permanent -06 on 2026-06-18.
Morocco moves to permanent +00 on 2026-09-20.
More integer overflow bugs have been fixed in zic.
Changes to future timestamps
Alberta's 2026-03-08 spring forward was its last foreseeable clock
change, as it moved to permanent -06 thereafter. (Thanks to Roozbeh
Pournader and others.) Model this with its traditional abbreviation
CST. Although the change to permanent -06 legally took place on
2026-06-18, temporarily model the change to occur on 2026-11-01 at
02:00 instead, for the same reason we introduced a similarly
temporary hack for British Columbia in 2026b.
