Fix kernel-doc processing of SYSCALL wrappers.
The SYSCALL wrapper patches played havoc with kernel-doc for
syscalls. Syscalls that were scanned for DocBook processing
reported warnings like this one, for sys_tgkill:
Warning(kernel/signal.c:2285): No description found for parameter 'tgkill'
Warning(kernel/signal.c:2285): No description found for parameter 'pid_t'
Warning(kernel/signal.c:2285): No description found for parameter 'int'
because the macro parameters all "look like" function parameters,
although they are not:
/**
* sys_tgkill - send signal to one specific thread
* @tgid: the thread group ID of the thread
* @pid: the PID of the thread
* @sig: signal to be sent
*
* This syscall also checks the @tgid and returns -ESRCH even if the PID
* exists but it's not belonging to the target process anymore. This
* method solves the problem of threads exiting and PIDs getting reused.
*/
SYSCALL_DEFINE3(tgkill, pid_t, tgid, pid_t, pid, int, sig)
{
...
This patch special-cases the handling SYSCALL_DEFINE* function
prototypes by expanding them to
long sys_foobar(type1 arg1, type1 arg2, ...)
