Commit 984d74a720 ("sysrq: rcu-ify __handle_sysrq") replaced
spin_lock_irqsave() calls with rcu_read_lock() calls in sysrq. Since
rcu_read_lock() does not disable preemption, faulthandler_disabled() in
__do_page_fault() in x86/fault.c returns false. When the code later calls
might_sleep() in the pagefault handler, we get the following warning:
BUG: sleeping function called from invalid context at ../arch/x86/mm/fault.c:1187
in_atomic(): 0, irqs_disabled(): 0, pid: 4706, name: bash
Preemption disabled at:[<ffffffff81484339>] printk+0x48/0x4a
To fix this, we release the RCU read lock before we crash.
Tested this patch on linux 3.18 by booting off one of our boards.

The wakeup variable keeps track of the 2 edge interrupts needed to detect
wakeup from deep sleep, when the second edge interrupt is detected the
wake byte is injected into the tty buffer.
On some boards due to noisy GPIO pins an interrupt is detected as soon as
the wakeup irq is enabled and before the variable is reset leading to
bogus wakeup bytes being injected into the serial buffer.
To protect against this, make sure the wakeup interrupt is enabled after
all the state variables are reset to protect against spurious wakeups.
