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 6f4f2723d085 ("x86
cpufreq: Make trace_power_frequency cpufreq driver independent"), which
didn't update the intel_idle native hardware cpuidle driver.
