Commit9b081e1080("powerpc: port 64 bits pgtable_cache to 32 bits") mixed up PMD_INDEX_SIZE and PMD_CACHE_INDEX a couple of times. This resulted in 64s/hash/4k configs to panic at boot with a false positive error check. Fix that and simplify error handling by moving the check to the caller.

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.
