[ Upstream commit 5c41aaad409c097cf1ef74f2c649fed994744ef5 ]
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.

arch,hexagon: Convert smp_mb__*()2014-04-18T12:20:35ZPeter Zijlstra2014-03-13T18:00:36Zurn:sha1:94cf42f823bc904305b0ee93a09bcd51ba380497
Hexagon uses asm-gemeric/barrier.h and its smp_mb() is barrier().
Therefore we can use the default implementation that uses smp_mb().
