Handle floating point state better in ptrace. The code now correctly distinguishes between PTRACE_[GS]ETFPREGS and PTRACE_[GS]ETFPXREGS. The FPX requests get handed off to arch-specific code because that's not generic. get_fpregs, set_fpregs, set_fpregs, and set_fpxregs needed real implementations. Something here exposed a missing include in asm/page.h, which needed linux/types.h in order to get gfp_t, so that's fixed here.
