This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to
avoid invoking cache line invalidation if the driver will just handle it
via a sync_for_cpu or sync_for_device call.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

When a CPU is disabled via CPU hotplug, cpu_foreign_map is not updated.
This could result in cache management SMP calls being sent to offline
CPUs instead of online siblings in the same core.
Add a call to calculate_cpu_foreign_map() in the various MIPS cpu
disable callbacks after set_cpu_online(). All cases are updated for
consistency and to keep cpu_foreign_map strictly up to date, not just
those which may support hardware multithreading.

At first, we prefer to use mips clockevent device, so we decrease the
rating of hpet clockevent device.
For hpet, if HPET_MIN_PROG_DELTA (minimum delta of hpet programming) is
too small and HPET_MIN_CYCLES (threshold of -ETIME checking) is too
large, then hpet_next_event() can easily return -ETIME. After commit
c6eb3f70d4 ("hrtimer: Get rid of hrtimer softirq") this will cause
a RCU stall.
So, HPET_MIN_PROG_DELTA must be sufficient that we don't re-trip the
-ETIME check -- if we do, we will return -ETIME, forward the next event
time, try to set it, return -ETIME again, and basically lock the system
up. Meanwhile, HPET_MIN_CYCLES doesn't need to be too large, 16 cycles
is enough.
This solution is similar to commit f9eccf2461 ("clocksource/drivers
/vt8500: Increase the minimum delta").
By the way, this patch ensures hpet count/compare to be 32-bit long.

This patch is borrowed from x86 hpet driver and explaind below:
Due to the overly intelligent design of HPETs, we need to workaround
the problem that the compare value which we write is already behind
the actual counter value at the point where the value hits the real
compare register. This happens for two reasons:
1) We read out the counter, add the delta and write the result to the
compare register. When a NMI hits between the read out and the write
then the counter can be ahead of the event already.
2) The write to the compare register is delayed by up to two HPET
cycles in AMD chipsets.
We can work around this by reading back the compare register to make
sure that the written value has hit the hardware. But that is bad
performance wise for the normal case where the event is far enough in
the future.
As we already know that the write can be delayed by up to two cycles
we can avoid the read back of the compare register completely if we
make the decision whether the delta has elapsed already or not based
on the following calculation:
cmp = event - actual_count;
If cmp is less than 64 HPET clock cycles, then we decide that the event
has happened already and return -ETIME. That covers the above #1 and #2
problems which would cause a wait for HPET wraparound (~306 seconds).

When Core-0 handle SMP_ASK_C0COUNT IPI, we should make other cores to
see the result as soon as possible (especially when Store-Fill-Buffer
is enabled). Otherwise, C0_Count syncronization makes no sense.
BTW, array is more suitable than per-cpu variable for syncronization,
and there is a corner case should be avoid: C0_Count of Core-0 can be
really 0.

Almost everyone implements dma_set_mask the same way, although some time
that's hidden in ->set_dma_mask methods.
This patch consolidates those into a common implementation that either
calls ->set_dma_mask if present or otherwise uses the default
implementation. Some architectures used to only call ->set_dma_mask
after the initial checks, and those instance have been fixed to do the
full work. h8300 implemented dma_set_mask bogusly as a no-ops and has
been fixed.
Unfortunately some architectures overload unrelated semantics like changing
the dma_ops into it so we still need to allow for an architecture override
for now.

Since 2009 we have a nice asm-generic header implementing lots of DMA API
functions for architectures using struct dma_map_ops, but unfortunately
it's still missing a lot of APIs that all architectures still have to
duplicate.
This series consolidates the remaining functions, although we still need
arch opt outs for two of them as a few architectures have very
non-standard implementations.
This patch (of 5):
The coherent DMA allocator works the same over all architectures supporting
dma_map operations.
This patch consolidates them and converges the minor differences:
- the debug_dma helpers are now called from all architectures, including
those that were previously missing them
- dma_alloc_from_coherent and dma_release_from_coherent are now always
called from the generic alloc/free routines instead of the ops
dma-mapping-common.h always includes dma-coherent.h to get the defintions
for them, or the stubs if the architecture doesn't support this feature
- checks for ->alloc / ->free presence are removed. There is only one
magic instead of dma_map_ops without them (mic_dma_ops) and that one
is x86 only anyway.
Besides that only x86 needs special treatment to replace a default devices
if none is passed and tweak the gfp_flags. An optional arch hook is provided
for that.

The majority of SMP platforms handle their IPIs through do_IRQ()
which calls irq_{enter/exit}(). When a call function IPI is received,
smp_call_function_interrupt() is called which also calls
irq_{enter,exit}(), meaning irq_count is raised twice.
When tick broadcasting is used (which is implemented via a call
function IPI), this incorrectly causes all CPU idle time on the core
receiving broadcast ticks to be accounted as time spent servicing
IRQs, as account_process_tick() will account as such if irq_count is
greater than 1. This results in 100% CPU usage being reported on a
core which receives its ticks via broadcast.
This patch removes the SMP smp_call_function_interrupt() wrapper which
calls irq_{enter,exit}(). Platforms which handle their IPIs through
do_IRQ() now call generic_smp_call_function_interrupt() directly to
avoid incrementing irq_count a second time. Platforms which don't
(loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt()
wrapped in irq_{enter,exit}().
