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.

Currently in hpte_need_flush() if there is no batch pending we always do a global TLB flush, which is inefficient if the mm has never run on another thread. Instead do the same check that __flush_tlb_pending() does and check if a local flush is sufficient when batch->active is false. Instead of open-coding it we use mm_is_thread_local().
