Unless we want to test with THP, then we shouldn't require it to be
configured by the host kernel. Unfortunately, even advising with
MADV_NOHUGEPAGE does require it, so check for THP first in order
to avoid madvise failing with EINVAL.

Add a regression test for commit 671ddc700fd0 ("KVM: nVMX: Don't leak
L1 MMIO regions to L2").
First, check to see that an L2 guest can be launched with a valid
APIC-access address that is backed by a page of L1 physical memory.
Next, set the APIC-access address to a (valid) L1 physical address
that is not backed by memory. KVM can't handle this situation, so
resuming L2 should result in a KVM exit for internal error
(emulation).

If netfilter changes the packet mark, the packet is rerouted. The
ip_route_me_harder family of functions fails to use the right sk, opting
to instead use skb->sk, resulting in a routing loop when used with
tunnels. With the next change fixing this issue in netfilter, test for
the relevant condition inside our test suite, since wireguard was where
the bug was discovered.

Commit cad6967ac108 ("fork: introduce kernel_clone()") replaced "_do_fork()"
with "kernel_clone()". The ftrace selftests reference the fork function in
several of the tests. The rename will make the tests break, but if those
names are changed in the tests, they would then break on older kernels. The
same set of tests should pass older kernels if they have previously passed.
Obviously, a new test may not work on older kernels if the test was added
due to a bug or a new feature.
The setup of ftracetest will now create a $FUNCTION_FORK bash variable
that will contain "_do_fork" for older kernels and "kernel_clone" for newer
ones. It figures out the proper name by examining /proc/kallsyms.
Note, available_filter_functions could also be used, but because some tests
should be able to pass without function tracing enabled, it could not be
used.

The ION android code has long been marked to be removed, now that we
dma-buf support merged into the real part of the kernel.
It was thought that we could wait to remove the ion kernel at a later
time, but as the out-of-tree Android fork of the ion code has diverged
quite a bit, and any Android device using the ion interface uses that
forked version and not this in-tree version, the in-tree copy of the
code is abandonded and not used by anyone.
Combine this abandoned codebase with the need to make changes to it in
order to keep the kernel building properly, which then causes merge
issues when merging those changes into the out-of-tree Android code, and
you end up with two different groups of people (the in-kernel-tree
developers, and the Android kernel developers) who are both annoyed at
the current situation. Because of this problem, just drop the in-kernel
