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. CPU: Montecito 1.4GHz, 4 sockets, 8core. NFS + Montecito + 2.6.23-rc2 23 SIGILLS in 1000 trial ext3 + Montecito + 2.6.23-rc2 0 erros in 1000 trial NFS + Itanium2(model2 revision2) + 2.6.23-rc2 0 errors in 1000 trial NFS + Montecito + 2.6.23-rc2 + patch. 0 errors in 1000 trial == Thanks, -Kame
