ARM: 8329/1: miscellaneous vdso infrastructure, preparation Define the layout of the data structure shared between kernel and userspace. Track the vdso address in the mm_context; needed for communicating AT_SYSINFO_EHDR to the ELF loader. Add declarations for arm_install_vdso; implementation is in a following patch. Define AT_SYSINFO_EHDR, and, if CONFIG_VDSO=y, report the vdso shared object address via the ELF auxiliary vector. Note - this adds the AT_SYSINFO_EHDR in a new user-visible header asm/auxvec.h; this is consistent with other architectures.
