find_bit API and bitmap API are closely related, but inclusion paths
are different - include/asm-generic and include/linux, correspondingly.
In the past it made a lot of troubles due to circular dependencies
and/or undefined symbols. Fix this by moving find.h under include/linux.

When testing in userspace, UBSAN pointed out that shifting into the sign
bit is undefined behaviour. It doesn't really make sense to ask for the
highest set bit of a negative value, so just turn the argument type into
an unsigned int.
Some architectures (eg ppc) already had it declared as an unsigned int,
so I don't expect too many problems.

Building drivers/mtd/nand/raw/nandsim.c on arch/hexagon/ produces a
printk format build warning. This is due to hexagon's ffs() being
coded as returning long instead of int.
Fix the printk format warning by changing all of hexagon's ffs() and
fls() functions to return int instead of long. The variables that
they return are already int instead of long. This return type
matches the return type in <asm-generic/bitops/>.
../drivers/mtd/nand/raw/nandsim.c: In function 'init_nandsim':
../drivers/mtd/nand/raw/nandsim.c:760:2: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'long int' [-Wformat]
There are no ffs() or fls() allmodconfig build errors after making this
change.

Hexagon uses asm-gemeric/barrier.h and its smp_mb() is barrier().
Therefore we can use the default implementation that uses smp_mb().
