The debug info is not very useful and embeds build paths because elf-vdso.so.o is built without CFLAGS, breaking reproducibility of elf-vdso.so.o and thus the kernel. Just stop passing debug flags to amd64_vdso.sh. Reviewed by: kib MFC after: 2 weeks Sponsored by: Klara, Inc.

It is easy to forget to configure DEBUG_VFS_LOCKS, and when one does, no vnode lock assertions are checked when INVARIANTS is configured, so bugs can arise. This has happened to me more than once, and the overhead over DEBUG_VFS_LOCKS does not appear to be high enough to prohibit folding it into INVARIANTS, so let's do that. The change makes vnode lock assertions useful in plain INVARIANTS kernels, and guards VOP debug routines on INVARIANTS rather than DEBUG_VFS_LOCKS. Further, invariants are now checked by plain assertions rather than having various sysctls to finely control what happens the checks fail. The extra complexity didn't seem particularly useful and is at odds with how we handle debugging most everywhere else.

Some of the defined names are not the direct 1:1 mapping with vendor and device names used by Linux device drivers. Introduce a p(roduct)alias so we can map the one device entry I came across without much extra hassle and generate a name device drivers know about: palias BROADCOM_CYPRESS_43439 CYPRESS_43439 Sponsored by: The FreeBSD Foundation Reviewed by: emaste Differential Revision: https://reviews.freebsd.org/D46455 (cherry picked from commit b4ef1b1be753952a4aafa505817164624f712c37)
Generate defined names which match the ones in the Linux drivers (a lot more); given we are likely to have drivers only based on those one way or another there is absolutely no reason to fight over differently generated names for device and vendor IDs.

The input file used to have a $FreeBSD$ tag on the first line and we recorded that in the generated files to know which versions they were based on. With the removal of $FreeBSD$ the logic was not quite correct anymore; fix that to generate proper header files again.

The latest ota is the first one in FreeBSD that treats 0 + "0xf" as being '0' instead of '15'. Don't use this old trick anymore to convert from hexidecimal to a number. Write a function to do that instead. This fixes kernel.bin building on arm*. awk on 14 doesn't need this, but to build FreeBSD stable/14's kernel.bin on 15 we'll need it, so fast MFC.

We only want to produce syscall.mk for the main syscall table so default to not producing it (send it to /dev/null) and add a syscalls.conf to sys/kern to trigger the creation of sys/sys/syscall.mk. This eliminates the need for entries in other syscalls.conf files and is a cleaner pattern going forward.
