Subsystem:
arm port, arm64 port (aarch64 architecture), generic vdso library, library code, linux for powerpc (32-bit and 64-bit), loongarch, mips, risc-v architecture, s390 architecture, sparc + ultrasparc (sparc/sparc64), the rest, x86 architecture (32-bit and 64-bit) · Maintainers:
Russell King, Catalin Marinas, Will Deacon, Andy Lutomirski, Thomas Gleixner, Vincenzo Frascino, Andrew Morton, Madhavan Srinivasan, Huacai Chen, Thomas Bogendoerfer, Paul Walmsley, Palmer Dabbelt, Albert Ou, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, "David S. Miller", Andreas Larsson, Linus Torvalds, Ingo Molnar, Borislav Petkov, Dave Hansen
All architectures using the generic vDSO library should enable VDSO_CHECK. Now that this is the case, enable VDSO_CHECK automatically.
