This patch introduces f2fs_map_blocks structure likewise ext4_map_blocks.
Now, f2fs uses f2fs_map_blocks when handling get_block.

Convert away lib/ from deprecated simple_strto*() interfaces.
(int []){0}[0] expression is anonymous variable, don't be scared.
Filesystem option parser code does parsing 1.5 times: first to know
boundaries of a value (args[0].from, args[0].to) and then actual
parsing with match_number(). Noody
This patch moves some inode-related definitions from node.h to f2fs.h to

kstrto*() and kstrto*_from_user() family of functions were added
to help with parsing one integer written as string to proc/sysfs/debugfs
files. But they have a limitation: string passed must end with \0 or \n\0.
There are enough places where kstrto*() functions can't be used because of

Rewrite kstrto*() functions through parse_integer().
_kstrtoul() and _kstrtol() are removed because parse_integer()
can dispatch based on BITS_PER_LONG saving function call.
Also move function definitions and comment one instance.
Remove redundant boilerplate comments from elsewhere.

Adds support for IA32_PQR_ASSOC MSR writes during task scheduling.
The high 32 bits in the per processor MSR IA32_PQR_ASSOC represents the
CLOSid. During context switch kernel implements this by writing the
CLOSid of the cgroup to which the task belongs to the CPU's
IA32_PQR_ASSOC MSR.
