X86 doesn't have an ASID hardware feature to the best of my knowledge,
except related to the virtualization extensions when working with
guest memory spaces. Would it make sense to use root page table
pointers for this? I don't know specifically how page tables are
managed in Linux, so I don't know if that would actually work. The
root page table pointer is in the CR3 register.

Maybe put these ifs together with an or? It's not hugely better
since the body is so short, but it's something to consider.

user/kernel code.
Debug flags are ExecUser, ExecKernel, and ExecAsid. ExecUser and
ExecKernel are set by default when Exec is specified. Use minus
sign with ExecUser or ExecKernel to remove user or kernel tracing
respectively.
