2014-04-23powerpc: No need to use dot symbols when branching to a functionAnton Blanchard
binutils is smart enough to know that a branch to a function descriptor is actually a branch to the functions text address. Alan tells me that binutils has been doing this for 9 years. Signed-off-by: Anton Blanchard <anton@samba.org>
2007-12-01[POWERPC] pasemi: Don't enter powersaving states from elevated astatesOlof Johansson
When the PWRficient cpus are entered into powersavings states, the astate is automatically dropped down to 0. While we still restore it when we come out of idle, it can still cause some weird effects with respect to performance (especially since it takes a while to ramp up to higher astates). So, to avoid this, don't enter power savings when the cpufreq driver (or user) has set higher astates than 0. The restore is still required, since there's a chance the astate has been raised from the other cpu while the idling one was asleep. Signed-off-by: Olof Johansson <olof@lixom.net>

Powersave support on PA6T. Right now it only uses 'doze' mode, and will default to no savings (spin). Signed-off-by: Olof Johansson <olof@lixom.net> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
