The use of 64-bit math on i386 causes build failures:
vdso_standalone_test_x86.c:(.text+0x101): undefined reference to `__umoddi3'
vdso_standalone_test_x86.c:(.text+0x12d): undefined reference to `__udivdi3'Commit adb19fb66ee (Documentation: add makefiles for more targets) is
now building this by default, so it's failing the kernel build entirely.Switching the declaration from uint64_t to time_t does the right thing
and handles the x32 case automatically.Signed-off-by: Jeff Mahoney

glibc versions older than 2.16 don't include sys/auxv.h which this
executable uses.
Since we don't have a good way to test for specific glibc versions in
kbuild, just disable it for now.Signed-off-by: Peter Foley

This adds a new vdso_test.c that's written entirely in C. It also
makes all of the vDSO examples work on 32-bit x86.Cc: Stefani Seibold

This thing is hopelessly x86_64-specific: it's an example of how to
access the vDSO without any runtime support at all.Signed-off-by: Andy Lutomirski

It turns out that parsing the vDSO is nontrivial if you don't already
have an ELF dynamic loader around. So document it in Documentation/ABI
and add a reference CC0-licenced parser.This code is dedicated to Go issue 1933:
