| * Name: syscall_clock_systimer |
| * |
| * Description: |
| * In the kernel build, proxying for clock_systimer() must be handled |
| * specially. In the kernel phase of the build, clock_systimer() is |
| * macro that simply accesses a global variable. In the user phase of |
| * the kernel build, clock_systimer() is a proxy function. |
| * |
| * In order to fill out the table g_funclookup[], this function will stand |
| * in during the kernel phase of the build so that clock_systemer() will |
| * have an address that can be included in the g_funclookup[] table. |
