Subject: [ 13/52] asm-generic: Use __BITS_PER_LONG in statfs.h

3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "H. Peter Anvin" <hpa@...ux.intel.com>

commit f5c2347ee20a8d6964d6a6b1ad04f200f8d4dfa7 upstream.

<asm-generic/statfs.h> is exported to userspace, so using
BITS_PER_LONG is invalid.  We need to use __BITS_PER_LONG instead.

This is kernel bugzilla 43165.
