[ Upstream commit 81e96851ea32deb2c921c870eecabf335f598aeb ]
The clang integrated assembler requires the 'cmp' instruction to have a length prefix here:
arch/x86/math-emu/wm_sqrt.S:212:2: error: ambiguous instructions require an explicit suffix (could be 'cmpb', 'cmpw', or 'cmpl') cmp $0xffffffff,-24(%ebp) ^
Make this a 32-bit comparison, which it was clearly meant to be.
