We already have the helper, we can convert the rest of the kernel
mechanically using:

  git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/'

This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

Apart from adding the helper function itself, the rest of the kernel is
converted mechanically using:

  git grep -l 'atomic_inc.*mm_users' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_users);/mmget\(\1\);/'

This is needed for a later patch that hooks into the helper, but might

vsnprintf extension %Z<foo> is non-standard C.  Suggest the use of %z
instead.

Miscellanea:

 - Correct the misuse of type string PRINTF_0xDECIMAL type strings are
   supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the
   type check in case I forget this again sometime in the future.

 - Improve the mechanism to find these defects so all 3 current checks
   are done on the format string

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.

Use BUILD_BUG_ON in a couple ATM drivers.

In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement.  Hopefully this patch inspires
someone else to trim vsprintf.c more.

I wrote a simple script to find new typo not in spelling.txt.
(https://github.com/jinb-park/find-linux-kernel-typo)

and get following result:

	[ rank ]
	63 paramaters
	18 alignement
	9 strucuture
	....

The number means how many files include the typo.
This patch adds these common typo.

Commit 50bed2e2 ("sg: disable interrupts inside sg_copy_buffer")
introduced disabling interrupts in sg_copy_buffer() since atomic uses of
miter required it due to use of kmap_atomic().

However, as commit 8290e2d2 ("scatterlist: atomic sg_mapping_iter()
no longer needs disabled IRQs") acknowledges disabling interrupts is no
longer needed for calls to kmap_atomic() and therefore unneeded for
miter ops either, so remove it from sg_copy_buffer().
