Sometimes a single capability could be listed multiple times with differing matches(), e.g, CPU errata for different MIDR versions. This breaks verify_local_cpu_feature() and this_cpu_has_cap() as we stop checking for a capability on a CPU with the first entry in the given table, which is not sufficient. Make sure we run the checks for all entries of the same capability. We do this by fixing __this_cpu_has_cap() to run through all the entries in the given table for a match and reuse it for verify_local_cpu_feature().

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.
