[PATCH 14/15] vdso: Add asm-generic/vdso/vsyscall.h
From: Thomas Weißschuh <hidden>
Date: 2026-09-09 08:52:01
Also in:
linux-arm-kernel, linux-mips, linux-riscv, linux-s390, linuxppc-dev, lkml, loongarch, sparclinux
Subsystem:
generic include/asm header files, generic vdso library, 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:
Arnd Bergmann, Andy Lutomirski, Thomas Gleixner, Vincenzo Frascino, 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
Most architectures' asm/vdso/vsyscall.h do not define any symbols. Add an empty asm-generic variant and replace the pointless architecture-specific copies.
