Subject: [PATCH 2/10] X86_64: local_irq_disable() is redundant after
 local_irq_save()

From: Jiri Kosina <jkosina@...e.cz>

X86_64: local_irq_disable() is redundant after local_irq_save()

arch/x86_64/kernel/time.c::hpet_calibrate_tsc() contains
local_irq_disable() call after local_irq_save(). This looks
redundant.
