[v2,0/2] Fix sloppy typing in the FB area copying routines

Here are 2 patches against the 'master' branch of Linus' 'linux.git' repo...

In {cfb|sys}_copyarea(), the local variable bits_per_line is needlessly typed
as *unsigned long* -- which is a 32-bit type on the 32-bit arches and a 64-bit
type on the 64-bit arches;; that variable's value is derived from the __u32
typed fb_fix_screeninfo::line_length field (multiplied by 8u) and a 32-bit
*unsigned int* type should still be enough to store the # of bits per line.
