[PATCH V13 02/14] 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.
