Split out the non-ARM specific portions of SYS_WRITE to a reusable function. This handles all GuestFD. This removes the last use of common_semi_syscall_len. Note that gdb_do_syscall %x reads target_ulong, not int. Reviewed-by: Luc Michel <lmichel@kalray.eu> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
