Subject: [PATCH] kernel config: Explicitly enable some stuff not enabled by
 'make alldefconfig'

List of what to enable taken from https://lwn.net/Articles/672587/.
This doesn't change the resulting x86 configs, but is more useful for
other architectures. For instance, POSIX_MQUEUE is currently missing
on ARM.
