* 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.
