Roland McGrathf6b46eb2008-01-30 13:30:41 +0100[diff] [blame]2 * Linker script for 64-bit vDSO.
3 * We #include the file to define the layout details.
4 * Here we only choose the prelinked virtual address.
5 *
6 * This file defines the version script giving the user-exported symbols in
7 * the DSO. We can define local symbols here called VDSO* to make their
8 * values visible using the asm-x86/vdso.h macros from the kernel proper.
