   4 Subject: powerpc/booke64: set RI in default MSR
   5
   6 From: Laurentiu Tudor <laurentiu.tudor@nxp.com>
   7
   8 commit 5266e58d6cd90ac85c187d673093ad9cb649e16d upstream.
   9
  10 Set RI in the default kernel's MSR so that the architected way of
  11 detecting unrecoverable machine check interrupts has a chance to work.
  12 This is inline with the MSR setup of the rest of booke powerpc
  13 architectures configured here.
