um: fix FPU state preservation around signal handlers
This patch makes UML saves/restores FPU state from/to the fpstate in pt_regs when setting up or returning from a signal stack, rather than calling ptrace directly. This ensures that FPU state is correctly preserved around signal handlers in a multi-threaded scenario. Signed-off-by: Eli Cooper <elicooper@gmx.com>
