git-mfc: Add an ignore-list feature
Commit hashes listed in ~/.git-mfc-ignore are not listed in output of
git-mfc --dangling or --pending. This is handy for silencing output
about commits that are tagged for MFC or as fixing another commit, but
which were not MFCed for some reason or other.

hwpstate_intel(4): Introduce a CPU ID cache

hwpstate_amd(4): Restore CPU ID cache after introducing cpu_get_pcpuid()
Using cpu_get_pcpuid() directly or having a CPU ID cache does not really
make any significant difference. With cache: Less function calls, less
space on stack, but an additional allocation in the softc, who stays
permanently. Without cache: Some function calls, but one less slot in
the softc, and no data duplication (but that info never changes).
The main reason for this change is to reduce conflicts with some
work-in-progress by aokblast@.
While here, move the check that a per-CPU structure is provided by the
bus from the attach to the probe method, as it is already used by
hwpstate_probe_pstate() there.

ice(4): Add support for 40G maximal PMD speed
E823 backplane devices may support 40G as maximal PMD speed.
Extend port topology reading logic to handle this case.

ice(4): Fix link speed after changing cable type
When interface was connected to a link partner with a cable
type limitting maximum supported speed, e.g. SFP+ cable
in 25G port, driver incorrectly saved a supported speed
as the user configured speed. This prevented interface
from using all supported speeds after switching cable to SFP28.
Link was established at 10G as supported by previously used
SFP+ cable. Don't set user requested speed unless actually
configured by an user, to allow automatic selection of highest
available speed. Only when user sets custom config
using advertise_speed sysctl save it and try
to apply after cable is changed.
Also don't save initial supported speeds if FW supports
reporting default PHY config.

tests: Fix build if TIOCSTI is not defined
Some downstream projects (e.g. ElectroBSD) have removed the TIOCSTI
We already have some components (such as mail and tcsh) that build

riscv/pmap.c: Handle spurious kernel page faults in critical sections
The Privileged ISA specification permits caching of invalid PTEs
12.2.1. Supervisor Memory-Management Fence Instruction), which may
result in a spurious page fault. Such faults are handled by 'pmap_fault'
which locks the kernel pmap before inspecting and possibly updating the
offending L2 entry.
Unfortunately, spurious faults may also occur when we're already holding
the kernel_pmap lock or running in a critical section, where any attempt
to grab the pmap lock will result in a kernel panic.
Fix this avoidable panic by performing a lockless lookup to determine
whether a valid kernel mapping exits and flushing appropriate TLB entry.
