[PATCH 0/2] fix some problems for cpufreq

Hi Rafael and Viresh

Sorry to trouble you again. As for:
"acpi-cpufreq: get the cur_freq from acpi_processor_performance states"
I do it again, and add the other patch.

patch #1: acpi-cpufreq: make the freq_table store the same freq value

I think it can work. The set of available states which come
from acpi won't change. Just like the power would be remove,
the acpi driver will do that:
call
->acpi_processor_ppc_has_changed
->cpufreq_update_policy
->acpi_ppc_notifier_block.notifier_call
->acpi_processor_ppc_notifier
->cpufreq_verify_within_limits
The progress will change the policy's min_freq and max_freq
while it won't change the set of states(freq_tables).

patch #2: cpufreq: show the real avail freqs with the freq_table

when the min_freq and max_freq change, we should sync the availble
freqs.

Regards,
Wang
