File already contains code that is common along balloon
drivers so rename it to reflect its contents.
mm/balloon_compaction.c -> mm/balloon.c

Remove it from files which do not actually use it.

The OF node in the GPIO library is deprecated and soon
will be removed.
GPIO library now accepts fwnode as a firmware node, so
switch the driver to use it.

Scratch this, it has some flaws.

With Best Regards,

One more user outside of GPIO library and pin control folders needs
to be updated to use fwnode instead of of_node. To make this easier
introduce a helper in property.h and convert the user.
Note, the helper will be useful not only for the current users,
but any future ones that want to replace of

Rather than incurring a division or requesting too many random bytes for
the given range, use the prandom_u32_max() function, which only takes
the minimum required bytes from the RNG and avoids divisions.

Rather than truncate a 32-bit value to a 16-bit value or an 8-bit value,
simply use the get_random_{u8,u16}() functions, which are faster than
wasting the additional bytes from a 32-bit value.

Matt reported that scripts/decodecode doesn't work for the instruction

Although the previous commit made the powerpc instruction dump usable
with scripts/decodecode, there are still some problems.
Because the dump is split across multiple lines, the script doesn't cope
with printk timestamps or caller info.
That can be fixed by printing the entire dump on one line,

On some architecture NO_IRQ is 0, on other architectures it is -1.
