Both rp_loc and pfs_loc can be in the register stack area _or_ they can be in the memory stack area, the latter occurs when a struct pt_regs is pushed. Correct the validation check on these fields to check for both stack areas. Not allowing for memory stack locations means no backtrace past ia64_leave_kernel, or any other code that uses PT_REGS_UNWIND_INFO. Signed-off-by:
