[Xen-devel] [PATCH RFC V8 4/17] xen: Defer spinlock setup until boot CPU setup

[Raghavendra K T <raghavendra.kt@xxxxxxxxxxxxxxxxxx>]

From: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>

There's no need to do it at very early init, and doing it there
makes it impossible to use the jump_label machinery.
