Good point :)
The reason these first 2 patches were included in this patchset is
because patch 3 depended on patch 1 (particularly due to the
modifications to posix_cpu_timers_init_group() which happen to use
ACCESS_ONCE after initializing the thread_group_cputimer lock). Likewise
patch 2 depended on patch 1. Thus, I included these changes to make
applying these patches a bit simpler.
