Currently we do not provide a config fragment for the rseq selftests but
there are several options which are either required or helpful for
running them:
- CONFIG_RSEQ is required for obvious reasons, it is enabled by default
but it doesn't hurt to specify it in case the user is usinsg a
defconfig that disables it.
- CONFIG_RSEQ_DEBUG_DEFAULT_ENABLE turns on runtime debug checks which
would for example have helped spot some of the recent issues we've
seen on arm64:
https://lore.kernel.org/all/87zf2u28d1.ffs@tglx/
- CONFIG_DEBUG_RSEQ enables debugging on configurations that don't have
generic entry support.
- CONFIG_RSEQ_SLICE_EXTENSION is tested by the slice_test test, the
test will fail without it.
Add a configuration fragment which enables these options, helping
encourage CI systems and people doing manual testing to run the tests
with all the features and additional checks. We also enable
CONFIG_DEBUG_KERNEL and CONFIG_EXPERT which are dependencies for these
options.
