An upcoming mesa-freedreno uprev will require a couple crosvm policy
updates. In particular setscheduler/setaffinity, for the same reasons
that AMD requires them.
BUG=b:179519741
TEST=Start crostini with upstream mesa MR that starts requiring
setscheduler/setaffinity

MALI GPU driver calls this for printing debug information. Just

The build-time seccomp compiler for aarch64 complains that it doesn't
recognize open, epoll_wait, recv, mmap2, dup2, poll, mkdir, or stat.
I tried to propose a change to upstream minijail to make it aware of
these syscalls, but the calls are in various forms of deprecation
so upstream is doubting the sanity of the policy files.
I applied the following mapping: open->openat, epoll_wait->epoll_pwait,
recv->recvfrom, mmap2->mmap, dup2->dup3, poll->ppoll, mkdir->mkdirat,
and stat->statx. In many cases the new syscall was already present so I
just deleted the old one.
BUG=None
TEST=Ran compile_seccomp_policy.py with an unmodified minijail until
it stopped complaining. I don't have an arm device for runtime testing.
Wrote an app to emulate the execution of the first 400 syscall #s though
the bpf filter and verified that the list that matches the filter is the
same as the policy file.

Minijail's policy compiler complains when there's multiple
unconditional rules for a syscall. In most cases the rules
are redundant to common_device.policy.
BUG=None
TEST=Ran compile_seccomp_policy.py until it stopped
complaining.
