We allocate V_mfchashtbl with HASH_NOWAIT (which maps to M_NOWAIT), so
this allocation may fail. As we didn't handle that failure we could end
up dereferencing a NULL pointer later (e.g. during X_ip_mrouter_done()).
Do the obvious thing and fail out if we cannot allocate the table.

It seems this was an "emergency" knob to revert a newly introduced
behavior. Overall, we want better system-wide signal receive latency,
and it doesn't seem that some contrary policy was ever needed (and if
that comes up, it should rather be implemented, e.g., per-process).

As the assembly uses the ENTRY macro it already supports BTI, so mark

Now the kernel and modules are built with branch protection we can
enablethe Guarded Page flag in the page tables. This causes indirect
branches to a location without a correct landing pad instruction to
raise an exception.
This should help mitigate some attacks where a function pointer is
changed to point somewhere other than the start of the function,
however it doesn't stop an attacker pointing it to an unintended
function.

Old binaries do not set acpi.rsdp early enough. So when we boot with an
older loader.efi from an ESP that's not been updated, we assume there's
no ACPI on this system. This is unwise. Put a band-aide on this until we
can implement a proper 'feature' variable that the binary reports so we
can do conditionals for things like this in the future.
This is at best a rapid-response stop-gap.

Many tests are failing on AlmaLinux 9 because ZTS could not destroy the
pool in cleanup. This was due to $PWD being set to '.' instead of the
expected full path. This patch sets $PWD to the full path.

The tranditional build makes multiple passes through the tree.
The DIRDEPS_BUILD visits each directory only once per architecture,
thus makefiles should be able to everything they need in a single pass.
The use of TZS!= when doing make(*install*)
only works if the directory has previously been visited to do zoneinfo
since before the zoneinfo target is run TZS will be empty.
To fix this, have the zoneinfo target capture the list of files to
zoneinfo, and install-zoneinfo use that list.
Rename that target to zonefiles - since that is now what it does.
This is more efficient - we only gather the list of zones when it is
likely to have changed, and allows the makefile to do everything in a
single pass.

lua was previously unable to determine ACPI presence because this

This patch resolves that by detecting ACPI early (similar to
