Comparing the assembler listing
  123 004c 10BC                 ldmfd   sp!, {r4}
- 124 004e 84F30388             msr     psr, r4
+ 124 004e 84F30388             msr     xpsr_nzcvq, r4
  125 0052 62B6                 cpsie   i

"xpsr_nzcvq" is a valid replacement for the offending plain "psr", producing
the same code with no warnings. If no objections arise, I will apply in some
days.
