There are just two major changes
Renamed local_irq functions to raw_local_irq in irq.c.
Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug.

Microblaze needs to do lock_init very soon because MMU init calls lock functions.
Here is the explanation from Peter Zijlstra why we have to enable
__ARCH_WANTS_INTERRUPTS_ON_CTSW.
"So we schedule while holding rq->lock (for obvious reasons), but since
lockdep tracks held locks per tasks, we need to transfer the held state
from the prev to the next task. We do this by explicity calling
spin_release(&rq->lock) in context_switch() right before switch_to(),
and calling spin_acquire(&rq->lock) in
finish_task_switch()->finish_lock_switch().
Now, for some reason lockdep thinks that interrupts got enabled over the
context switch (git grep __ARCH_WANTS_INTERRUPTS_ON_CTSW arch/microblaze
doesn't seem to turn up anything).
Clearly trying to acquire the rq->lock with interrupts enabled is a bad
idea and lockdep warns you about this."

This is working implemetation but the problem is that
Microblaze misses frame pointer that's why is there
big loop which trace and show all addresses which are in text.
It shows addresses which are in registers, etc.
This is problem and this is the reason why all Microblaze
traces are wrong. There is an option to do hacks and trace
the kernel code but this is too complicated.

This patch adds support for phoenix interrupt framework. New iInterrupt
status register A, B, C are introduced in Phoenix and are cleared on write.
Due to the differences in interrupt handling with respect to TWL4030,
twl6030-irq.c is created for TWL6030 PMIC

No idea if this platform actually uses cpufreq_get(), but it doesn't
have any cpufreq drivers. That's not to say it doesn't use cpufreq_get()
in its drivers. LH7a40x is unmaintained anyhow, and should probably
be killed off.

Fix:
arch/arm/mach-sa1100/generic.c:117: error: redefinition of 'cpufreq_get'
include/linux/cpufreq.h:299: error: previous definition of 'cpufreq_get' was here
cpufreq_get() is used on these platforms to tell drivers what the CPU
frequency is, and therefore the bus frequency - which is critical for
setting the PCMCIA and LCD timings. Adding ifdefs to these drivers to
select cpufreq_get() or some other interface adds confusion. Making
these drivers use some other interface for the normal paths and cpufreq
stuff for the cpufreq notifier is insane as well.
(Why x86 can't provide a version of cpufreq_get() which returns the
CPU frequency when CPUFREQ is disabled is beyond me, rather than
requiring a dummy zero-returning cpufreq_get(). Especially as they
do:
unsigned long khz = cpufreq_get(cpu);
if (!khz)
khz = tsc_khz;
In other words, if CPUFREQ is disabled, get it from tsc_khz - why
not provide a dummy cpufreq_get() which returns tsc_khz?)

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.
This patch renames few common drivers twl4030* files to twl* to enable

When the VFP notifier is called for flush_thread(), we may be
preemptible, meaning we might migrate to another CPU, which means
referencing the current CPU number without some form of locking is
invalid, and can cause data corruption.
For the most cases, this isn't a problem since atomic notifiers are run
under rcu lock, which for most configurations results in preemption
being disabled - except when the preemptable tree-based rcu
implementation is selected.
Let's make it safe anyway.
