History
Konrad Rzeszutek Wilk e0fc17a936 xen/spinlock: Don't enable them unconditionally. 
The git commit a945928ea2
('xen: Do not enable spinlocks before jump_label_init() has executed')
was added to deal with the jump machinery. Earlier the code
that turned on the jump label was only called by Xen specific
functions. But now that it had been moved to the initcall machinery
it gets called on Xen, KVM, and baremetal - ouch!. And the detection
machinery to only call it on Xen wasn't remembered in the heat
of merge window excitement.

This means that the slowpath is enabled on baremetal while it should
not be.
