[PATCH 1/2] powerpc: Make stack frame marker upper case

[Michael Ellerman]

Now that the stack frame regs marker is only 32-bits it is not as
obvious in memory dumps and easier to miss, eg:

  c000000004733e40 0000000000000000 0000000000000000  |................|
  c000000004733e50 0000000000000000 0000000000000000  |................|
  c000000004733e60 0000000000000000 0000000000000000  |................|
  c000000004733e70 7367657200000000 0000000000000000  |sger............|
  c000000004733e80 a700000000000000 708897f7ff7f0000  |........p.......|
  c000000004733e90 0073428fff7f0000 208997f7ff7f0000  |.sB..... .......|
  c000000004733ea0 0100000000000000 ffffffffffffffff  |................|
  c000000004733eb0 0000000000000000 0000000000000000  |................|

So make it upper case to make it stand out a bit more:

  c000000004733e70 5347455200000000 0000000000000000  |SGER............|
