    Subject[PATCH RFC V8 2/17] x86/ticketlock: Don't inline _spin_unlock when using paravirt spinlocks
    From: Raghavendra K T <raghavendra.kt@linux.vnet.ibm.com> 

    The code size expands somewhat, and its better to just call
    a function rather than inline it.

    Thanks Jeremy for original version of ARCH_NOINLINE_SPIN_UNLOCK config patch,
    which is simplified.

    Paravirtualized spinlocks allow a pvops backend to replace the
    spinlock implementation with something virtualization-friendly
