uml: ptrace floating point fixes
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.
