The host process table base is stored in the partition table by calling the function native_register_process_table(). Currently this just sets the entry in memory and is missing a subsequent cache invalidation instruction. Any update to the partition table should be followed by a cache invalidation instruction specifying invalidation of the caching of any partition table entries (RIC = 2, PRS = 0). We already have a function to update the partition table with the required cache invalidation instructions - mmu_partition_table_set_entry(). Update the native_register_process_table() function to call mmu_partition_table_set_entry(), this ensures all appropriate invalidation will be performed.

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.
