Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/davej/cpufreq
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/davej/cpufreq:
[CPUFREQ] Remove pointless printk from p4-clockmod.
[CPUFREQ] Fix section mismatch for powernow_cpu_init in powernow-k7.c
[CPUFREQ] Fix section mismatch for longhaul_cpu_init.
[CPUFREQ] Fix section mismatch for longrun_cpu_init.
[CPUFREQ] powernow-k8: Fix misleading variable naming
[CPUFREQ] Convert pci_table entries to PCI_VDEVICE (if PCI_ANY_ID is used)
[CPUFREQ] arch/x86/kernel/cpu/cpufreq: use for_each_pci_dev()
[CPUFREQ] fix brace coding style issue.
[CPUFREQ] x86 cpufreq: Make trace_power_frequency cpufreq driver independent
[CPUFREQ] acpi-cpufreq: Fix CPU_ANY CPUFREQ_{PRE,POST}CHANGE notification
[CPUFREQ] ondemand: don't synchronize sample rate unless multiple cpus present
[CPUFREQ] unexport (un)lock_policy_rwsem* functions
[CPUFREQ] ondemand: Refactor frequency increase code
[CPUFREQ] powernow-k8: On load failure, remind the user to enable support in BIOS setup
[CPUFREQ] powernow-k8: Limit Pstate transition latency check
[CPUFREQ] Fix PCC driver error path
[CPUFREQ] fix double freeing in error path of pcc-cpufreq
[CPUFREQ] pcc driver should check for pcch method before calling _OSC
[CPUFREQ] fix memory leak in cpufreq_add_dev
[CPUFREQ] revert "[CPUFREQ] remove rwsem lock from CPUFREQ_GOV_STOP call (second call site)"
Manually fix up non-data merge conflict introduced by new calling
conventions for trace_power_start() in commit 6f4f2723d0
("x86
cpufreq: Make trace_power_frequency cpufreq driver independent"), which
didn't update the intel_idle native hardware cpuidle driver.

|

----------------------------
|
||||
|
||||
What: lock_policy_rwsem_* and unlock_policy_rwsem_* will not be
|
||||
exported interface anymore.
|
||||
When: 2.6.33
|
||||
Why: cpu_policy_rwsem has a new cleaner definition making it local to
|
||||
cpufreq core and contained inside cpufreq.c. Other dependent
|
||||
drivers should not use it in order to safely avoid lockdep issues.
