ptrace regset interface relies on ELF_NGREG for ceiling the size of user request. So any larger request (even if legit) would be clipped. The existing def of ELF_NGREG didn't use user_regs_struct and was technically one placeholder short (stop_pc) - although the current code would still work because pt_regs includes a bunch of extra fields, making ELF_NGREG >= sizeof(struct user_regs_struct)/sizeof(long) But we need to remove this ambiguity, specially since pt_regs should NOT be directly associated with with anything userspace-ish.
