[PATCH 17/17] vdso: Remove kconfig symbol GENERIC_VDSO_DATA_STORE
From: Thomas Weißschuh <hidden>
Date: 2024-12-16 14:11:04
Also in:
linux-arch, linux-arm-kernel, linux-mips, linux-riscv, linux-s390, lkml, loongarch
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, 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, Michael Ellerman, Huacai Chen, Thomas Bogendoerfer, Paul Walmsley, Palmer Dabbelt, Albert Ou, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Linus Torvalds, Ingo Molnar, Borislav Petkov, Dave Hansen
All users of HAVE_GENERIC_VDSO have been switched over to the generic storage logic. The dedicated kconfig symbol can be removed and replaced by HAVE_GENERIC_VDSO.
