Hi Andi, Here's a couple of patches to fix up COMPAT_VDSO: The first is a straightforward implementation of Jan's original idea of relocating the VDSO to match its mapped location. Unlike Jan and Zach's version, I changed it to relocate based on the phdrs rather than the sections; the result is pleasantly compact. The second patch takes advantage of the fact that all the COMPAT_VDSO work happens at runtime now, and allows compat mode to be enabled dynamically. If you specify vdso=2 on the kernel command line, it comes up in compat mode; vdso=1 is normal vdso mode, and vdso=0 disables vdso altogether. You can also switch modes with sysctl. Changes since last posting: - rebase sections as well as phdrs - relocate symbols - more robust DT_tag handling - handle dynamic compat mode switches a bit better Thanks to Jan and Roland for the review.
