SPARC provides lzcnt instruction (with VIS3) which can be used to
optimize fls, __fls and fls64 functions. For the systems that supports
lzcnt instruction, we now do boot time patching to use sparc
optimized fls, __fls and fls64 functions.
v3->v4:
- Fixed a typo.
v2->v3:
- Using ENTRY(), ENDPR
fls will now require a boot time patching on T4 and above.
Redefining it under arch/sparc/lib.

The current way of using various reader, writer and waiting biases

The setting of owner field is specific to rwsem-xadd, it is not needed

As the generic rwsem-xadd code is using the appropriate acquire and
release versions of the atomic operations, the arch specific rwsem.h

remove those arch specific rwsem.h and stop building asm/rwsem.h to

This patch enables readers to optimistically spin on a
rwsem when it is owned by a writer instead of going to sleep
directly. The rwsem_can_spin_on_owner() function is extracted
out of rwsem_optimistic_spin() and is called directly by
rwsem_down_read_failed() and rwsem_down_write_failed().

Because of writer lock stealing, it is possible that a constant
stream of incoming writers will cause a waiting writer or reader to
wait indefinitely leading to lock starvation.
The mutex code has a lock handoff mechanism to prevent lock starvation.
This patch implements a similar lock handoff mec
Because of writer lock stealing and optimistic spinning, writers
were preferred over readers in rwsem. However, preferring readers is
generally good for performance. However, we need to do it in a way
that won't starve writers as an incoming stream of readers will not
allow a wakeup call to happen
The rwsem_down_read_failed*() functions were relocted from above the
optimistic spinning section to below that section. This enables
them to use functions in that section in future patches. There is no
code change.

When the rwsem is owned by reader, writers stop optimistic spinning
simply because there is no easy way to figure out if all the readers
are actively running or not. However, there are scenarios where
the readers are unlikely to sleep and optimistic spinning can help
performance.

So increase SDIO CIU frequency from 1250Hz to 5000Hz by
