28 * This file defines - for the TSAR_MIPS32 architecture - types that can be used
29 * by both the kernel and the user applications.
30 *
31 * - the <reg_t> type, is used by the hal_user_syscall() function, called by
32 *   several user-level libraries to pass syscall arguments to the  kernel,
33 *   and used by the do_syscall() kernel function, to analyse arguments.
34 *   It is also used by the hal_*_irq() kernel functions to save/restore
35 *   the SR register value.
