Should mips64 kernel support time(2) system call for n32/n64 ABI?

Both 2.4 and 2.6 kernel define __NR_time and use sys_time.  But
sys_time in kernel/time.c is not 64-bit clean.

We should remove definition of __NR_time from unistd.h (and sys_time
from scall_64.S), or implement local version of sys_time.

Which way to go?

 time(2) is obsolete (by gettimeofday(2)) and should be removed for new
implementations.

Then could you apply these patches?

for 2.4:

 I can, but they need an approval from Ralf.  Ralf, is the change OK?
