Currently, sizeof(struct parsed_partitions) may be 64KB in 32bit arch,
so it is easy to trigger page allocation failure by check_partition,
especially in hotplug block device situation(such as, USB mass storage,
MMC card, ...), and Felipe Balbi has observed the failure.
This patch does below
It isn't necessary to read the information of partitions whose No.
is equal and more than state->limit since only maximum state->limit
partitions will be added inside rescan_partitions().
That is also what other kind of partitions are doing.

This eliminates the contention I am seeing in __cpufreq_cpu_get.
It also nicely stages the lock to be replaced by the rcu.

In general rwlocks are discourged so we are moving it to use the rcu instead.
This does require a bit of care since the cpufreq_driver_lock protects both
the cpufreq_driver and the cpufreq_cpu_data array.
Also since many of the function pointers on cpufreq_driver may sleep when
called we have to
I am noticing the cpufreq_driver_lock is quite hot.
On an idle 512 system perf shows me most of the system time is spent on this
lock. This is quite significant as top shows 5% of time in system time.
My solution was to first convert the lock to a rwlock and then to the rcu.

Perfection is something very rarely achieved. That's why we work with

Until recently, when an negative ID is specified, idr functions used
to ignore the sign bit and proceeded with the operation with the rest
of bits, which is bizarre and error-prone. The behavior recently got
changed so that negative IDs are treated as invalid but we're
triggering WARN_ON_ONCE()
