cpu0 is waiting for the other cpu respond ipi, but one cpu is blocked on getting &tasklist_lock
while irq is disabled and it will not respond ipi. If all the operation of &tasklist_lock is irq-disabled,
the &tasklist_lock will become available before the owner respond ipi, so the blocked cpu will get the
&tasklist_lock.

ARM: errata: Workaround for Cortex-A12 erratum 821420
On Cortex-A12 (r0p0, r0p1), in very rare timing conditions, a sequence of
VMOV to Core registers instructions, for which the second one is in the
shadow of a branch or abort, can lead to a deadlock when the VMOV
instructions are issued out-of-order. This workaround setting bit 1 of
the Internal Feature Register prevents the erratum.
