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