3.9-rc1 powerpc ptrace.c: 'brk.len' is used uninitialized

[Philippe De Muyter]

Hello Michael,

bisect tells me that since your commit 9422de3e953d0e60eb95f5430a9dd803eec1c6d7 
"powerpc: Hardware breakpoints rewrite to handle non DABR breakpoint registers",
compiling linux fails with :

  cc1: warnings being treated as errors
  arch/powerpc/kernel/ptrace.c: In function 'arch_ptrace':
  arch/powerpc/kernel/ptrace.c:1450: warning: 'brk.len' is used uninitialized in this function
  arch/powerpc/kernel/ptrace.c:1352: note: 'brk.len' was declared here

could you look at that ?

Thanks

Philippe
