Kernel Build Problems

Problem: OpenVZ 2.6.18 + patch-ovz028stab047.1 fails to build

Building a 2.6.18 kernel with patch-ovz028stab047.1 fails in Stage 2 with an error related to grsecurity.

Solution

Make the following 1-line patch to grsecurity/grsec_disabled.c, configure the kernel to disable grsecurity and build the kernel again.

I believe this problem is solved in the 049 version of the patch.
