Merge master.kernel.org:/pub/scm/linux/kernel/git/davej/cpufreq
* master.kernel.org:/pub/scm/linux/kernel/git/davej/cpufreq: [CPUFREQ] longhaul compile fix. [CPUFREQ] Advise not to use longhaul on VIA C7. [CPUFREQ] set policy->curfreq on initialization [CPUFREQ] Trivial cleanup for acpi read/write port in acpi-cpufreq.c [CPUFREQ] fixes typo in cpufreq.c
