arm: mm: Exclude additional mem_map entries from free

A previous patch addressed the issue of move_freepages_block()
trampling on erronously freed mem_map entries for the bank end
pfn. We also need to restrict the start pfn in a
complementary manner.

Also make macro usage consistent by adopting the use of
round_down and round_up.

fix BUG on cpufreq policy init failure

cpufreq_register_driver sets cpufreq_driver to a structure owned (and
placed) in the caller's memory. If cpufreq policy fails in its ->init
function, sysdev_driver_register returns nonzero in
cpufreq_register_driver. Now, cpufreq_register_driver returns an error
without setting cpufreq_driver back to NULL.

Usually cpufreq policy modules are unloaded because they propagate the
error to the module init function and return that.

So a later access to any member of cpufreq_driver causes bugs like:

It's all cause by weird fail path handling in cpufreq_register_driver.
To fix that, shuffle the code to do proper handling with gotos.

remove redundant sprintf from request_module call.

Since format string handling is part of request_module, there is no
need to construct the module name. As such, drop the redundant sprintf
and heap usage.

Don't set stat->last_index to -1 if the pol->cur has incorrect value.

If the driver submitted an non-existing pol>cur value (say it
used the default initialized value of zero), when the cpufreq
stats tries to setup its initial values it incorrectly sets
stat->last_index to -1 (or 0xfffff...). And cpufreq_stats_update
tries to update at that index location and fails.

This can be caused by:

stat->last_index = freq_table_get_index(stat, policy->cur);

not finding the appropiate frequency in the table (b/c the policy->cur
is wrong) and we end up crashing. The fix however is
concentrated in the 'cpufreq_stats_update' as the last_index
(and old_index) are updated there. Which means it can reset
the last_index to -1 again and on the next iteration cause a crash.

Without this patch, the following crash is observed:

md: dm-crypt: Add option to re-use a new global work-queue.

Typically, dm-crypt instances each have their own set of kcrypt/kcrypt_io
work-queues. This patch adds an option which will create one set of
work-queues on init, and re-uses them for all dm-crypt target instances
in order to cut down on resource overhead on embedded systems.

NOTE: If you use stacked dm-crypt instances, then enabling this option
may cause a deadlock.
