Documentation spelling fix.

cpufreq-2.6.0-test4-rename_userspace
Rename drivers/cpufreq/userspace.c to

cpufreq-2.6.0-test4-fix_userspace
Fix a couple of oddities in the userspace governor

cpufreq-2.6.0-test4-separate_governors_core

	Completely separate governors from policies. Governors are for
	CPUfreq drivers which have a ->target callback, Polcies are for
	CPUfreq drivers which have a ->setpolicy callback. Also, the
	"hardwired" governors "powersave" and "performance" are removed.

cpufreq-2.6.0-test4-separate_governors_governors
Add the "performance" and "powersave" governors as modules. Also add a config option so that the default governor [which is loaded and enabled at boot] is started. Note that if you select "performance" here, the CPU will be set to the highest possible frequency even if the CPU was booted at a lower frequency. If you select "userspace", the frequency will stay the same.

cpufreq-2.6.0-test4-separate_governors_ppc cpufreq-2.6.0-test4-separate_governors_sh cpufreq-2.6.0-test4-separate_governors_sparc64 cpufreq-2.6.0-test4-separate_governors_x86
Small fixes necessary to separate the governors from policies.

cpufreq-2.6.0-test4-separate_governors_arm
These changes allow for easier Kconfig usage on ARM. And more features for SA11x0 users.
