got this build failure:

  ./arch/x86/include/asm/rwsem.h:106:2: error: ‘asm’ operand has impossible constraints

with the attached config and with:

  gcc version 5.3.1 20151207 (Red Hat 5.3.1-2) (GCC) 

Please send a delta patch for this bug too - I'll squash the fix into the 
originating commit.

Thanks,

	Ingo
