This is built into a test so needs the BTI elf note for the rest of the

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.

This is a follow-up patch to https://reviews.freebsd.org/D42459
that modifies the loader lua to use the correct loader variables

This also fixes a bug where ACPI can be inadvertently disabled when

lua was previously unable to determine ACPI presence because this
probing was postponed until the final loading and execution of the
kernel.
This patch resolves that by detecting ACPI early (similar to
the order of operations in the legacy i386 loader).

indicate an unsupported fstype leaving ENOENT to indicate errors such
as a missing mount point or invalid path. This allows nmount(2) to
better distinguish these cases and avoid treating a missing device

While here, change mount(2) to return EINVAL instead of ENODEV for an

never see a COOKIE/COOKIE_ACK exchange. We should consider HEARTBEAT_ACK

This ensures that such connections do not time out earlier than
