i8253_lock needs to be a real spinlock in preempt-rt, i.e. it can
not be converted to a sleeping lock.Convert it to raw_spinlock and fix up all users.

Along the lines of d6c585a4342a2ff627a29f9aea77c5ed4cd76023, add IRQF_TIMER
flag for all timer interrupts This ensures that timer interrupts won't be
disabled on suspend and not threaded for PREEMPT_RT.Signed-off-by: Wu Zhangjin

Some of the were relying into smp.h being dragged in by another header
which of course is fragile. uses smp_processor_id()
only in macros and including smp.h there leads to an include loop, so
don't change cpu-info.h.Signed-off-by: Ralf Baechle

Pass clocksource pointer to the read() callback for clocksources. This

Impact: cleanup
It's unused, since about 1995. So remove all initialization of it in
preparation for actually removing the field.Signed-off-by: Rusty Russell

Impact: change calling convention of existing clock_event APIs
struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.Another single-patch change. For safety, we BUG_ON() in
clockevents_register_device() if it's not set.Signed-off-by: Rusty Russell

The pit_clockevent symbol is needlessly defined global. This patch makes
that variable static.Spotted by sparse. Compile-tested using Malta defconfig.

The timer code always calls the clock_event_device set_net_event and
set_mode methods with interrupts disabled, so no need to use
spin_lock_irqsave / spin_unlock_irqrestore for those.Signed-off-by: Ralf Baechle

The Jazz machines have to use the PIT timer for dyntick and highresolution
kernels. This may break because currently just like i386 used to do MIPS
uses two separate spinlocks in the actual PIT code and the PC speaker
code. So switch to do it the same that x86 currently does PIT locking.Signed-off-by: Ralf Baechle

While the PC speaker is wired up to the i8254 there is more to the i8254
than just the PC speaker so this code was getting in the way under its
current name.Signed-off-by: Ralf Baechle

The current pcspkr code combines the device and driver registration.
This patch splits these, putting the device registration in the arch
specific code.PowerPC and MIPS only have the pcspkr present sometimes.
