thermal: tsens8960: Increase the polling rate

Change the polling rate at which the sensors temperature
is read from 1 second to .25 seconds. On faster parts
there is a need to poll the temperature at a higher
frequency to improve reporting temperature changes.

block/partitions: optimize memory allocation in check_partition()

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 optimizations on the allocation of struct
parsed_partitions to try to address the issue:

- make parsed_partitions.parts as pointer so that the pointed memory can
  fit in 32KB buffer, then approximate 32KB memory can be saved

- vmalloc the buffer pointed by parsed_partitions.parts because 32KB is
  still a bit big for kmalloc

- given that many devices have the partition count limit, so only
  allocate disk_max_parts() partitions instead of 256 partitions always

fs/namespace.c: Activate NOATIME and NODIRATIME By Default
arm: Remove no-longer-required RCU_NONIDLE wrapper

Commit 21111be8 "ARM: Fix negative idle stats for offline cpu" moved call
to cpu_die() to occur outside of rcu_idle_enter()/rcu_idle_exit() section.
As a result, the RCU_NONIDLE() wrapper to complete() call in
arch/arm/kernel/process.c:cpu_die() is no longer required (and is
technically incorrect to have). Removing RCU_NONIDLE() wrapper also removes
this warning seen during CPU offline:
