Should ensure that they work. Need to be done for both native/compat C/R.
=== Fixes for older kernels ===
=== Fixes for older kernels ===
For kernels with backported mainline patches for 32-bit C/R (like vzkernel) there are a couple of things to do like different sizes of vdso/vvar (or vvar may not be even present).
