The contended_release tracepoint needs to hook queued_spin_unlock(), but architectures with a custom unlock define queued_spin_unlock() directly, leaving no single generic place to add the tracing. Introduce queued_spin_release() as the arch-overridable release primitive and make queued_spin_unlock() a generic wrapper around it. An architecture that only customizes the release can then override queued_spin_release() and inherit the generic wrapper. Rename the MIPS override to queued_spin_release() accordingly. x86 paravirt overrides queued_spin_unlock() directly and is left unchanged. No functional change intended.
