[PATCHv2 4/7] arch, mm: convert all architectures to use 5level-fixup.h
From: Kirill A. Shutemov <hidden>
Date: 2017-03-09 14:26:56
Also in:
linux-arch, lkml
Subsystem:
arm port, arm64 port (aarch64 architecture), linux for powerpc (32-bit and 64-bit), microblaze architecture, mips, nios2 architecture, openrisc architecture, qualcomm hexagon architecture, s390 architecture, s390 mm, sparc + ultrasparc (sparc/sparc64), superh, synopsys arc architecture, tensilica xtensa port (xtensa), the rest, user-mode linux (uml), x86 architecture (32-bit and 64-bit) · Maintainers:
Russell King, Catalin Marinas, Will Deacon, Madhavan Srinivasan, Michal Simek, Thomas Bogendoerfer, Dinh Nguyen, Simon Schuster, Jonas Bonn, Stefan Kristiansson, Stafford Horne, Brian Cain, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Gerald Schaefer, "David S. Miller", Andreas Larsson, Yoshinori Sato, Rich Felker, John Paul Adrian Glaubitz, Vineet Gupta, Chris Zankel, Max Filippov, Linus Torvalds, Richard Weinberger, Anton Ivanov, Johannes Berg, Thomas Gleixner, Ingo Molnar, Borislav Petkov, Dave Hansen
If an architecture uses 4level-fixup.h we don't need to do anything as it includes 5level-fixup.h. If an architecture uses pgtable-nop*d.h, define __ARCH_USE_5LEVEL_HACK before inclusion of the header. It makes asm-generic code to use 5level-fixup.h. If an architecture has 4-level paging or folds levels on its own, include 5level-fixup.h directly. Signed-off-by: Kirill A.
