mainlining shenanigans
8f3e474f3c
To correctly handle 32-bit and 64-bit mmap() syscalls in 64bit applications its required to have separate address bases to place a mapping. The tasksize can be used as an indicator to select the proper parameters for mmap_base(). This requires the following changes: - Add task_size argument to mmap_base() and make the calculation based on it. - Provide mmap_legacy_base() as a seperate function - Use the new functions in arch_pick_mmap_layout() [ tglx: Massaged changelog ] Signed-off-by: Dmitry Safonov <dsafonov@virtuozzo.com> Cc: 0x7f454c46@gmail.com Cc: linux-mm@kvack.org Cc: Andy Lutomirski <luto@kernel.org> Cc: Cyrill Gorcunov <gorcunov@openvz.org> Cc: Borislav Petkov <bp@suse.de> Cc: "Kirill A.

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.
