Commit41d0c2ecde("powerpc/powernv: Fix local TLB flush for boot and MCE on POWER9") introduced calls to __flush_tlb_power[89] from the cpufeatures code, specifying the number of sets to flush. However, these functions take an action argument, not a number of sets. This means we hit the BUG() in __flush_tlb_{206,300} when using cpufeatures-style configuration. This change passes TLB_INVAL_SCOPE_GLOBAL instead.

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.
