More than we'd like after rc8, but nothing very alarming either, just tying up loose ends before the release: Since we changed powernv to use cpufreq_get() from show_cpuinfo(), we see warnings with PREEMPT enabled. But the preempt_disable() in show_cpuinfo() doesn't actually prevent CPU hotplug as it suggests, so remove it. Two updates to the recently merged RFI flush code. Wire up the generic sysfs file to report the status, and add a debugfs file to allow enabling/disabling it at runtime. Two updates to xmon, one to add the RFI flush related fields to the paca dump, and another to not use hashed pointers in the paca dump. And one minor fix to add a missing include of linux/types.h in asm/hvcall.h, not seen to break the build in upstream, but correct anyway.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
