Subject: [PATCH] timekeeping: Remove __current_kernel_time()

The __current_kernel_time() function based on 'struct timespec' is no
longer recommended for new code, and the only user of this function
has been replaced by commit 6909e29fdefb ("kdb: use
__ktime_get_real_seconds instead of __current_kernel_time"). So now we
can remove this obsolete interface.
