Add an EDAC device flag and associated sysfs entries to
allow an EDAC driver to be configured to panic the kernel
if a correctable error is detected. Though correctable
errors (by definition) have no adverse system effects,
a panic may still be useful, since a correctable error may
be indicative of a marginal system state.

Add a check for cpu unbound deferrable timer expiry and raise
softirq for handling the expired timers so that the CPU can
process the cpu unbound deferrable times as early as possible
when a cpu tries to enter/exit idle loop.

In case of a kernel panic, only the panicking CPU does an entire
cache flush. This means that certain dirty cache lines in the
caches of the other CPUs may never get flushed. This gives us
improper RAM dumps. Add cache flushing for all the online CPUs.
The outer domain is not flushed since it is already being done by
the panicking CPU.

When a kernel panic occurs on one CPU, other CPUs are instructed to stop
execution via the IPI_CPU_STOP message. These other CPUs dump their stack,
which may not be good enough to reconstruct their context to perform
post-mortem analysis. Dump each CPU's context (before it started
processing the IPI) into a globally accessible structure and print them on
the dmesg/console to allow for easier post-mortem debugging.

As the best clocksource is not selected till core boot completion,
only periodic tick timer works and it increases jiffies by one at
every tick updates. If interrupt is disabled more than one tick(10ms),
timer interrupts are missed and jiffies can't be updated at every
10ms and It can be behind the real time. So make it possible to select
the best clocksource right after arm arch timer initialization, so that
jiffies can be increased by multiple counts since then.

that the best clocksource can be selected whenever it is available.

The irq_domain_remove() API expects all the irqs of the domain be cleared
before it is called, else it throws a warning. A framework creating a
radix tree to map all the irqs used by its clients cannot be sure if all
the clients cleared their irqs. Thus to avoid this warning, we can use
this API irq_dispose_all_tree_mappings() to ensure that all irqs
belonging to the domain are cleared before the domain is itself removed.
