pf: remove redundant zeroing
nlmsg_reserve_object() already zeroes the header before it gives it to
us, so there's no need to explicitly zero these fields again.

acpi: Make taskqueue only run on BSP
This is needed because when we add the suspend-to-idle loop, we only
want to break the BSP out of idle to process the taskqueue while keeping
all the others idled.
Currently assuming BSP to be CPU0, which may not always be the case on
non-x86.

nuageinit: set the hostname when user-data is missing
This address the situation reported here
https://github.com/freebsd/freebsd-src/pull/1952#issuecomment-3720210259
The user-data file was missing and the `sethostname` function is never
called. This commit adjusts slightly the logic to avoid the `exit()` call
when the `user-data` file is missing.

GCE: ARM64 Support: Add hw.pci.honor_msi_blacklist=0.
This is required for MSI support on GCE ARM64 instances which is
prerequisite to gve(4) not panicking at boot, and nvme(4) also has
a real sad time without interrupts. Tested on a variety of c4a VMs.
This is meant to be a temporary hack; long term fix would be to
check for the hypervisor and quirk gve(4) device with
PCI_QUIRK_ENABLE_MSI_VM.

GCE: Fix growfs path
The sed command was missing the ${DESTDIR} prefix, meaning it was
attempting to modify the build host's /etc/rc.d/growfs instead of
the target image's script. Tested in an arm64 builder that builds
as non-root.

GCE: Enable vtnet(4) Multiqueue.
Removes hw.vtnet.mq_disable=1.
This workaround was originally introduced nearly a decade ago to
address stability issues on KVM that have long since been resolved
in both the FreeBSD driver and the GCE hypervisor. Removing this
allows network interrupts to scale across multiple vCPUs.
Tested on n2-highcpu-16 VM with 15.0-RELEASE and confirmed multiple
queue pairs active and interrupts handling across cores.

zfs: emit .note.GNU-stack section for all ELF targets
On FreeBSD, linking the zfs kernel module with binutils ld 2.44 shows
the following warning:
ld: warning: aesni-gcm-avx2-vaes.o: missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
Some of the `.S` files under `module/icp/asm-x86_64/modes` check whether
to emit the `.note.GNU-stack` section using:
#if defined(__linux__) && defined(__ELF__)
We could add `&& defined(__FreeBSD__)` to the test, but since all other
`.S` files in the OpenZFS tree use:
#ifdef __ELF__
it would seem more logical to use that instead. Any recent ELF platform

tools/cam: Start to add the testing tools for CAM
Create a directory for testing tools arond CAM. These are snippets of
what will eventually be camio. At the moment, it was written using fbt
traces. This is OK, but fragile, so they need to be re-written with the
cam provider. cam_all_but_scsi.d is the first step. It shows how to do
this with the new cam dtrace provider.

loader.efi: Only use SPCR if enabled.
SerialPort in the SPCR is zeroed when serial redirection is disabled,
rather than the SPCR being omitted from the ACPI tables ony many
systems. Check to see that SerialPort.Address is non-zero before using.
FreeBSD would fail to boot on systems that could have a serial port
redireciton, but don't have it enabled because the loader would create a
bogus hw.uart.console. While one could unset this value to boot, you
couldn't do that automatically very easily. Instead, don't even look
at the SPCR table if the SerialPort is zero'd.
