[PATCH] s390: ptrace peek and poke
The special cases of peek and poke on acrs[15] and the fpc register are not handled correctly. A poke on acrs[15] will clobber the 4 bytes after the access registers in the thread_info structure. That happens to be the kernel stack pointer. A poke on the fpc with an invalid value is not caught by the validity check. On the next context switch the broken fpc value will cause a program check in the kernel. Improving the checks in peek and poke fixes this.
