This commit introduces a new vmtest.sh runner for vsock.
It uses virtme-ng/qemu to run tests in a VM. The tests are designed to
validate both G2H and H2G paths. The testing tools from tools from
tools/testing/vsock/ are reused. Currently, only vsock_test is used.
Only tested on x86.

An ovpn interface configured in MP mode will keep carrier always
on and let the user decide when to bring it administratively up and
down.
This way a MP node (i.e. a server) will keep its interface always
up and running, even when no peer is connected.

With this change ovpn is allowed to communicate to peers also via TCP.
Parsing of incoming messages is implemented through the strparser API.
Note that ovpn redefines sk_prot and sk_socket->ops for the TCP socket
used to communicate with the peer.
For this reason it needs to access inet6_stream_op
Doorbell feature is implemented by mapping the EP's MSI interrupt

Some replacement displays include third-party touch ICs which are
devoid of register descriptors. Create a fake data register descriptor
for such ICs and provide hardcoded default values.
It isn't possible to reliably determine if the touch IC is original or
not, so th

Currently, the ->gpwrap is not tested (at all per my testing) due to the
requirement of a large delta between a CPU's rdp->gp_seq and its node's
rnp->gpseq.
This results in no testing of ->gpwrap being set. This patch by default
adds 5 minutes of testing with ->gpwrap forced by lowering the delta

Some third party rmi4-compatible ICs don't expose their PDT entries
very well. Add a few checks to skip duplicate entries as well as entries
for unsupported functions.
This is required to support some phones with third party displays.

Some third party ICs claim to support f55 but report an electrode count

Nolibc is useful for selftests as the test programs can be very small,

Currently nolibc is only usable with kselftest.h, not the more

On ARM64, when running with --configs '36*SRCU-P', I noticed that only 1

instead of 36 for starting.
Fix it by checking for Image files, instead of bzImage which ARM does
not seem to have. With this I see all 36 instances running at the same
time in the batch.

Device capacity intended for use as system ram should be aligned to the
architecture-defined memory block size or that capacity will be silently

As hotplug dax memory becomes more prevelant, the memory block size
