Apparently on few architectures __fls is defined incorrectly. Fix this
by adjusting declarations to asm-generic ones.
As far as I can tell there should be no functional changes, but I don't
have devices to test it, so it was only compile tested.
Amadeusz Sławiński (2):
ARC: bitops: Change __fls
As per asm-generic definition and other architectures __fls should
return and accept unsigned long as its parameter.

As per asm-generic definition and other architectures __fls should
return unsigned long.
No functional change is expected as return value should fit in unsigned
long.
