ZTS: fix zpool_initialize_multiple_pools suspend race
zpool_initialize_multiple_pools verifies that "zpool initialize -a -s"
suspends initializing on all four pools. It starts initializing and,
without slowing it down, expects every pool to still be initializing
when the suspend runs.
On fast storage a pool can finish initializing before the suspend, so
"zpool initialize -a -s" reports "there is no active initialization"
and the pool's status is "completed" rather than "suspended". The
suspend command then fails the test intermittently.
Throttle zfs_initialize_chunk_size before the suspend phase, the same
way the zpool_wait_initialize_* tests do, so initializing stays active
through the suspend and cancel checks. The earlier phases that wait for
initializing to finish ("zpool wait" and "-w -a") are left at the
default chunk size so they still complete promptly.
The chunk size is saved and restored, and the pools are destroyed

[IR] Use pretty printing for mask in is_fpclass (#207653)
The second argument of `llvm.is_fpclass` is a mask, where each bit
represents a floating-point class. Understanding the check that the call
makes in an IR dump requires additional effort. To simplify the
interpretation of IR dumps, a previously implemented pretty-printing
mechanism can be used:
https://github.com/llvm/llvm-project/commit/39e7712ac520ccfc43383b3e9d6ea8cf2958b8e3.
This commit implements this mechanism for printing the arguments of
`llvm.is_fpclass`.
This change also fixes the printing of argument names: if an argument
name is absent, it is simply not printed.

[mlir][presburger] Avoid redundant zero-initialization in insertColumns (#199911)
When insertColumns does not trigger a physical reallocation, the inner
loop needlessly loops up to nReservedColumns - 1. This causes massive
redundant zero-writes on trailing columns that are already zero. This
patch truncates the inner loop start boundary to nColumns - 1, when the
reserved capacity is unchanged, optimizing the non-realloc path from
O(nRows * nReservedColumns) to O(nRows * nColumns).
nfsd: Garbage collect stray NFSv4 state
When a file is deleted on the NFS server by another client,
any NFSv4 state related to that file is left stranded.
This happens because the NFSv4 operations that free the
state use a CFH, which is set by a PutFH operation.
However, the PutFH fails with ESTALE because the file has
been deleted.
This patch adds a function called nfsrv_freestrandedstate()
that frees all the NFSv4 state related to a file and calls
this function when PutFH will be replying ESTALE.
While here, a helper function was defined to handle free'ng
of the nfslockfile structure and replaces the two places
where nearly identical code does this.

MFC after: 2 weeks
Add Rendition Verite V2100/V2200 (PCI/AGP) wsdisplay driver.
The driver supports:
- Fully accelerated console, provided that the user installs microcode
from the Windows driver (v20002d.uc). The driver runs unaccelerated
until root file system is available, or if the microcode is not present.
- Mode setting and DDC.
Redistribution terms of the original microcode are unclear, therefore
it must be obtained seprarately.
At some point in the future, we may just develop an alternative microcode,
since Verite RISC is documented and reverse engineering efforts have
filled the knowledge gaps.
