799209: CVE-2012-1097 kernel: regset: Prevent null pointer reference on readonly regsets

The MITRE CVE dictionary describes this issue as:

The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call.
