[Xen-devel] [PATCH v2 10/10] xen/arm: Call check_local_cpu_errata for secondary CPU only on boot

[Mirela Simonovic <mirela.simonovic@xxxxxxxxxx>]

Checking CPU errata should be done only when a CPU is initially booted.
It is assumed that the CPU which is hotplugged after the system/Xen boots,
was initially hotplugged during the system/Xen boot, so errata is checked
by each CPU only once, on boot.
