Christophe Leroy deec133580 powerpc/bitops: Fix possible undefined behaviour with fls() and fls64() 
[ Upstream commit 1891ef21d92c4801ea082ee8ed478e304ddc6749 ]

fls() and fls64() are using __builtin_ctz() and _builtin_ctzll().
On powerpc, those builtins trivially use ctlzw and ctlzd power
instructions.

Allthough those instructions provide the expected result with
input argument 0, __builtin_ctz() and __builtin_ctzll() are
documented as undefined for value 0.

The easiest fix would be to use fls() and fls64() functions
defined in include/asm-generic/bitops/builtin-fls.h and
include/asm-generic/bitops/fls64.h, but GCC output is not optimal:

00000388 <testfls>:
 388:   2c 03 00 00     cmpwi   r3,0
 38c:   41 82 00 10     beq     39c <testfls+0x14>
 390:   7c 63 00 34     cntlzw  r3,r3
 394:   20 63 00 20     subfic  r3,r3,32
 398:   4e 80 00 20     blr
 39c:   38 60 00 00     li      r3,0
 3a0:   4e 80 00 20     blr

000003b0 <testfls64>:
 3b0:   2c 03 00 00     cmpwi   r3,0
 3b4:   40 82 00 1c     bne     3d0 <testfls64+0x20>
 3b8:   2f 84 00 00     cmpwi   cr7,r4,0
 3bc:   38 60 00 00     li      r3,0
 3c0:   4d 9e 00 20     beqlr   cr7
 3c4:   7c 83 00 34     cntlzw  r3,r4
 3c8:   20 63 00 20     subfic  r3,r3,32
 3cc:   4e 80 00 20     blr
 3d0:   7c 63 00 34     cntlzw  r3,r3
 3d4:   20 63 00 40     subfic  r3,r3,64
 3d8:   4e 80 00 20     blr

When the input of fls(x) is a constant, just check x for nullity and
return either 0 or __builtin_clz(x). Otherwise, use cntlzw instruction
directly.

For fls64() on PPC64, do the same but with __builtin_clzll() and
cntlzd instruction. On PPC32, lets take the generic fls64() which
will use our fls(). The result is as expected:

00000388 <testfls>:
 388:   7c 63 00 34     cntlzw  r3,r3
 38c:   20 63 00 20     subfic  r3,r3,32
 390:   4e 80 00 20     blr

000003a0 <testfls64>:
 3a0:   2c 03 00 00     cmpwi   r3,0
 3a4:   40 82 00 10     bne     3b4 <testfls64+0x14>
 3a8:   7c 83 00 34     cntlzw  r3,r4
 3ac:   20 63 00 20     subfic  r3,r3,32
 3b0:   4e 80 00 20     blr
 3b4:   7c 63 00 34     cntlzw  r3,r3
 3b8:   20 63 00 40     subfic  r3,r3,64
 3bc:   4e 80 00 20     blr
