x86: use generic register names in struct user_regs_struct
Switch struct user_regs_struct (defined in <asm/user.h>, which is no longer exported to userspace) to using register names without e- or r-prefixes for both 32 and 64 bit x86. This is intended as a preliminary step in unifying this code between architectures. Also, be a bit more strict in truncating 32-bit "extended" segment register values to 16 bits. Signed-off-by: H.
