This patch set is for fixing SIGILL trouble in NFS by adding sync_icache_dcache() before set_pte(). (see patches for detail) Tested with my NUMA box and works well.
Chanves V6 -> V7 - dropped add-on patches for cpu family handling. For this post, I wrote an easy test for this SIGILL/NFS problem. Please verify. This is my result. == Distro: RHEL5.
