be used VERY early in boot; such consumers statically allocate the vmem
arena and boundary tags, and then explicitly add those static, private
boundary tags to the arena tag free list using the new function vmem_add_bts().
Vmem arenas that use private boundary tags will NOT consume the statically
allocated bootstrap tags used by the vmem system itself; the assumption is
that the consumer of such an arena knows what they're doing, and is responsible
for all necessary resource management. A macro, VMEM_EST_BTCOUNT(), is
provided to help such consumers size the static boundary tag store based
on the expected number of spans and early allocations. Once the private
tags are exhausted, the arena will dynamically allocate tags as usual.

from an arena. This is just a convenience wrapper around vmem_xalloc(),
that's just a bit more obvious how to use and performs some additional
sanity checks.

nvidia: add GA102/GA103/GA104/GA106/GA107 signed firmware
These NVIDIA-signed firmwares are required to enable the graphics engine
on Ampere GA10{2/3/4/6/7} Gpus.
Note that our drm2 driver won't use the GA10{2/3/4/6/7} firmware yet.
The updated Tu10x and Tu11x signed firmware are needed for at last the
nvidia T400 graphic card.
Tested this on i386 since that had been crashing before, but i386
doesn't see %zu for unsigned int as a problem.

The jmp_buf is not, in fact, uninitialized at the point of use, but
it doesn't hurt to narrow the scope a bit to between when the jmp_buf
is initialized by setjmp, and when the signal handler might be called
after sigaction.

Make sure to allocate enough space for the thread's stack for a guard
even though there shouldn't be one, so that when we run the thread,
it doesn't start with the stack pointer pointing into someone else's
allocation (like malloc) causing stack frames to trash another data
structure -- or causing the user of that data structure to trash the
stack frames.
