Fenghua Yu a1141e0b5c x86/fpu/xstate: Define and use 'fpu_user_xstate_size'
The kernel xstate area can be in standard or compacted format;
it is always in standard format for user mode. When XSAVES is
enabled, the kernel uses the compacted format and it is necessary
to use a separate fpu_user_xstate_size for signal/ptrace frames.
