[ORC] Construct EPCGenericMemoryAccess from ExecutionSession. (#215097)
Construct EPCGenericMemoryAccess objects from ExecutionSessions, rather
than ExecutorProcessControl objects. This is a step towards migrating
EPCGenericMemoryAccess off of raw callSPSWrapper* calls and on to the
new Proxy objects (d99bd3ed157).
igbv: Recover when the PF mailbox is unavailable
A VF reset can sanitize its retained queue registers even when the PF
does not complete the cooperative mailbox handshake. Keep those two
states separate. Do not program or enable the rings until both queue
sanitation and mailbox initialization have succeeded.
Report either initialization failure to iflib so the interface remains
stopped. Stopped admin and media-status passes now publish cached
link-down state without polling the mailbox. While the VF remains
administratively up, retry complete initialization after 250 ms, one
second, four seconds, and then at a capped eight-second interval.
Conditional iflib reset requests ensure an intervening administrative
down cancels a queued retry.
Avoid a redundant mailbox reset in the stop half of an immediate iflib
reinitialization; the following init performs the required reset.
Preserve the reset on an ordinary administrative stop and keep the
existing bounded queue-sanitation retry policy independent from
mailbox liveness recovery.

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.

cpuset(9): correct markup
- Remove `\(em` from .Nm section as it's not valid mandoc markup.
- Remove the section from the .Nm directive (it's handled under the .Dt
directive).

pmc(8): add missing headers to not rely on header pollution
This mutes a number of complains from g++ about needing specific headers
for functionality related to C strings and other function prototypes.

pmc(8): resolve -Wshadow issues
- Prefix all structs with the struct keyword to avoid collisions between
the types and variables with the same "name".
- Use `_` suffixed variables in initializers to distinguish input
parameters from public members [1].
Resolve some trailing whitespace issues while here.
NOTE: this doesn't resolve the -pedantic issue reported by g++ with
`pmchdr_cpuidinfo::cpuid` about the field being a flexible array in an
otherwise empty struct.
1. I generally do this the other way around, i.e., suffix private/protected
members with `_`, but these are public members in structs and I don't want
to introduce a lot of churn in calling code.

[PowerPC][AIX] Reject .weak_definition like ELF (#156072)
weak_definition is a Mach-O-specific directive and is not supported on
XCOFF. Previously it crashed the XCOFF streamer via report_fatal_error
in emitSymbolAttribute. Return false for MCSA_WeakDefinition like
MCELFStreamer does, so the parser rejects it with the same diagnostic as
ELF.
Revert "[libc] Add realpath to linux entrypoints" (#215156)
Reverts llvm/llvm-project#212925, the tests assume that `/tmp` is a
real, valid directory on the system, which is not true for all
buildbots. `libc-riscv32-qemu-yocto-fullbuild-dbg` in particular seems
to have a symlink or similar from `/tmp` to `/var/volatile/tmp`. See
https://github.com/llvm/llvm-project/pull/212925#issuecomment-5234167255.
