  since April 2012. Also enable NO_HZ_FULL on x86_64.)
- I added zipped modules ages ago, remove it from TODO.

* Post 3.5:
- Check if PaulMcK has fixed CONFIG_RCU_FAST_NO_HZ
Config TODOs:
* review & disable a bunch of the I2C, RTC, DVB, SOUND options.
@ -11,6 +8,3 @@ Spec file TODOs:
- Don't fail the build if a module is listed but not built (maybe).
- See if it can be tied into Kconfig instead of module names.
* investigate gzip modules. Everything should support this now?
Looks like about 70M savings per kernel installed.
