For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the alpha uses of the __cpuinit macros.

If you don't see any problems with it, then you don't have to do anything ; it will be submitted with all the rest of the __cpuinit removal work. On the other hand, if you want to carry this patch in with your other pending changes so as to handle conflicts with other pending work yourself, then that is fine too, as the commits can largely be treated independently.
