The patch titled
Subject: lib: bitmap: make nbits parameter of bitmap_{and,or,xor,andnot} unsigned
has been added to the -mm tree. Its filename is
lib-bitmap-make-nbits-parameter-of-bitmap_andorxorandnot-unsigned.patch
This patch should soon appear at
http://ozlabs.org/~akpm/mmots/broken-out/lib-bitmap-make-nbits-parameter-of-bitmap_andorxorandnot-unsigned.patch
and later at
http://ozlabs.org/~akpm/mmotm/broken-out/lib-bitmap-make-nbits-parameter-of-bitmap_andorxorandnot-unsigned.patch
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/SubmitChecklist when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days

Subject: lib: bitmap: make nbits parameter of bitmap_{and,or,xor,andnot} unsigned
This change is only for consistency with the changes to the other bitmap_*
functions; it doesn't change the size of the generated code: inside
BITS_TO_LONGS there is a sizeof(long), which causes bits to be interpreted
as unsigned anyway.
