This patch converts a if () BUG(); construct to BUG_ON();
which occupies less space, uses unlikely and is safer when

r4k_flush_cache_all() and r4k_flush_cache_mm() case: these are noop if
the CPU did not have dc_aliases. It would mean we do not need to care
about icache here.
r4k_flush_cache_range case: if r4k_flush_cache_mm() did not need to
care about icache, it would be same for this function.

Further incorporation of generic irq framework. Replacing __do_IRQ()
by proper flow handler would make the irq handling path a bit simpler
and faster.
* use generic_handle_irq() instead of __do_IRQ().
* use handle_level_irq for obvious level-type irq chips.
* use handle_percpu_irq for irqs marked as IRQ_PER_CPU.
* setup .eoi routine for irq chips possibly used with handle_percpu_irq.

This is a big irq cleanup patch.
* Use set_irq_chip() to register irq_chip.
* Initialize .mask, .unmask, .mask_ack field. Functions for these
method are already exist in most case.
* Do not initialize .startup, .shutdown, .enable, .disable fields if
default routines provided by irq_chip_set_defaults() were suitable.
* Remove redundant irq_desc initializations.
* Remove unnecessary local_irq_save/local_irq_restore, spin_lock.
With this cleanup, it would be easy to switch to slightly lightwait
irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ().
Though whole this patch is quite large, changes in each irq_chip are
not quite simple. Please review and test on your platform. Thanks.

During early boot mem init, some configs couldn't use __pa() to
convert virtual into physical addresses. Specially for 64 bit
kernel cases when CONFIG_BUILD_ELF64=n. This patch make __pa()
work for _all_ configs and thus make CPHYSADDR() useless.

__pa() was used by virt_to_page() and virt_addr_valid(). These
latter are used when kernel is initialised so __pa() is not
appropriate, we use virt_to_phys() instead.
Futhermore __pa() is going to take care of CKSEG0/XKPHYS
address mix for 64 bit kernels. This makes __pa() more complex
than virt_to_phys() and this extra work is not needed by
virt_to_page() and virt_addr_valid().
Eventually it consolidates virt_to_phys() prototype by making
its argument 'const'. this avoids some warnings that was due
to some virt_to_page() usages which pass const pointer.

ib_ucm_cleanup_events() holds file_mutex while calling ib_destroy_cm_id().
This can deadlock since ib_destroy_cm_id() flushes event handlers, and
ib_ucm_event_handler() needs file_mutex, too. Therefore, drop the
file_mutex during the call to ib_destroy_cm_id().

The ib_cm_establish() function is replaced with a more generic
ib_cm_notify(). This routine is used to notify the CM that failover
has occurred, so that future CM messages (LAP, DREQ) reach the remote
CM. (Currently, we continue to use the original path) This bumps the
userspace CM ABI.
New alternate path information is captured when a LAP message is sent
or received. This allows QP attributes to be initialized for the user
when a new path is loaded after failover occurs.
