Automatically enable the rcu_normal_wake_from_gp parameter on
systems with a small number of CPUs. The activation threshold
is set to 16 CPUs.
This helps to reduce a latency of normal synchronize_rcu() API
by waking up GP-waiters earlier and decoupling synchronize_rcu()
callers from regular callba
Currently the call_rcu() API does not check whether a callback
pointer is NULL. If NULL is passed, rcu_core() will try to invoke
it, resulting in NULL pointer dereference and a kernel crash.
To prevent this and improve debuggability, this patch adds a check
for NULL and emits a kernel stack trace

kselftest/mm: Clarify errors for pipe()
selftests/mm: Convert some cow error reports to ksft_perror()
selftests/mm: Don't compare return values to in cow

This prints the errno and a string decode of it.

Tweak the coding style for checking for non-zero return values.
While we're at it also remove a now redundant oring of the madvise()
return code.

It is not sufficiently clear what the individual tests in the cow test
program are checking so add messages for the failure cases.

I had cause to look at the vfork() support for GCS and realised that we
don't have any direct test coverage, this series does so by adding
vfork() to nolibc and then using that in basic-gcs to provide some
simple vfork() coverage.

To allow testing of vfork() support in the arm64 basic-gcs test provide an
implementation for nolibc, using the vfork() syscall if one is available
and otherwise clone3(). We implement in terms of clone3() since the order
of the arguments for clone() varies between architectures.

Ensure that we've got at least some coverage of the special cases around
vfork() by adding a test case in basic-gcs doing the same thing as the
plain fork() one - vfork(), do a few checks and then return to the parent.

This commit adds a new kernel selftest to verify RTNLGRP_IPV4_MCADDR
and RTNLGRP_IPV6_MCADDR notifications. The test works by adding and
removing a dummy interface and then confirming that the system
correctly receives join and removal notifications for the 224.0.0.1
and ff02::1 multicast addresses
