Hi,

Here are a couple of patches for linux-2.6.0-test4. A complete set can be
found here:

http://www.brodo.de/cpufreq_tmp/cpufreq-2.6.0-test4-all

Test reports are most welcome.


Individual patches [not sent to the list due to their size, but available at
http://www.brodo.de/cpufreq_tmp/ - just add the file name after the slash.]

cpufreq-2.6.0-test4-move_cpufreq
	Move kernel/cpufreq.c to drivers/cpufreq/cpufreq.c and remove $Id$
	tag.

cpufreq-2.6.0-test4-spelling_fix
	Documentation spelling fix.

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

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.
