The same:

[git|v2.6.32.16] weasel@thelma:/scratch/kernel/2.6.32.16$ nm arch/x86/kernel/pvclock.o
0000000000000000 r last_value
                 U native_read_tsc
0000000000000040 T pvclock_clocksource_read
0000000000000100 T pvclock_read_wallclock
0000000000000000 T pvclock_tsc_khz
                 U set_normalized_timespec
