The critical difference is that this version defaults to the compatible vdso-less mode instead of the modern incompatible mode. Changes from v1: - CONFIG_ENABLE_VDSO32_BY_DEFAULT now defaults to n - Improved the config text and description - Improved the kernel parameter docs Andy Lutomirski (2): x86: Remove compat vdso support x86_32: Remove user bit from identity map PDE Documentation/kernel-parameters.txt | 23 +++- arch/x86/Kconfig | 28 +++-- arch/x86/include/asm/elf.h | 4 - arch/x86/include/asm/fixmap.h | 8 -- arch/x86/include/asm/pgtable_types.h | 7 +- arch/x86/include/asm/vdso.h | 5 +- arch/x86/vdso/vdso-layout.lds.S | 2 +- arch/x86/vdso/vdso32-setup.c | 234 ++++------------------------------- arch/x86/vdso/vdso32/vdso32.lds.S | 2 - 9 files changed, 62 insertions(+), 251 deletions(-) -- 1.8.5.3
