ixgbe: Correct the PFVFRSSRK index range comment
PFVFRSSRK contains ten 32-bit RSS key words, numbered 0 through 9.
The previous inclusive range incorrectly ended at 10.

ixv: Reject unsupported E610 Hyper-V VFs
E610 Hyper-V VFs use PCI configuration space communication instead of
the native PF/VF mailbox. The generic E610 match currently attaches
native mailbox operations to those devices, and the imported Hyper-V
subdevice identifier is incorrect.
Correct the subdevice identifier to 0x00ff, as used by DPDK shared
ixgbe code, and reject that subtype until ixv has a complete Hyper-V
operations table.

iflib: Support recoverable initialization failure
The ifdi_init method cannot report an error, so iflib always marks an
interface running and enables its interrupts after the callback returns.
Drivers whose hardware initialization depends on an unavailable peer can
only return early and leave a falsely running interface.
Add iflib_init_failed() so a callback can leave the interface stopped.
Also add a conditional reset request for asynchronous recovery: it is
discarded if the interface is administratively down when the admin task
runs, preventing a queued retry from resurrecting a stopped interface.
Do not restore saved driver flags after an MTU or capability change when
initialization failed. Restoring the pre-init flags would overwrite the
stopped result with stale RUNNING state.
Document that reset requests require the caller to schedule the admin
task, that output remains blocked during recovery, and that iflib rather
than the driver owns the driver flags.

sysutils/firstboot-pkg-upgrade: Ignore OSVERSION
Without IGNORE_OSVERSION=yes, images built from HEAD or stable branches
will hang during boot waiting for the user to agree to install updates
every time OSVERSION gets bumped.
This is a no-op for releases, since OSVERSION never changes there.

[BFI] Preserve zero-mass exits in solveIrreducibleMass (#218140)
Fixes #217740.
Keep zero-mass exits in `solveIrreducibleMass`.
Although their mass is zero, these exits are later reused when building
enclosing irreducible SCCs... dropping them can change SCC membership
and eventually trigger the "**unhandled irreducible control flow**"
assertion.

[RISCV][NFC] Split PreRAExpandPseudo to new file (#218167)
Also update the comments on all the other ExpandPseudo passes, to

passes.
[clang] Trim large(-ish) includes from common headers (#216946)
Several widely included Clang headers pull in whole subsystems to name
types they only use through pointers, references, or declarations.
Because these headers sit underneath SourceManager.h, Sema.h, and
CompilerInstance.h, nearly every translation unit in Clang pays for
them, as well as many down-stream users of Clang.
Translation units across Clang and clang-tools-extra that were relying
on any of the removed transitive includes now include what they use.
Out-of-tree code that was relying on any of these transitive includes
needs the same treatment. The failure is an incomplete type or an
undeclared identifier at the point of use, and the fix is to include the
header that declares it; llvm/Support/VirtualFileSystem.h and AST/Attr.h
account for most of it, since Basic/FileManager.h and AST/GlobalDecl.h
are reached from so much of Clang.
Measured on a random 90 translation unit sample of clang's 1006 library
