Update 2.6.16.20 to 2.6.16.22, import 2.6.17.3, and mask 2.6.15-r7 for all systems except IP22, as this is the last known kernel that worked on IP22 in 64bit mode. 2.6.16.22 and 2.6.17.3 include SquashFS for the first time, as well as being the barrier between linuxthreads and nptl support. This means 2.6.17 is enabled only in the 2006.1 nptl sub-profiles, and masked in all other profiles. It is intended to be used with a transitional linuxthreads->nptl userland, as linuxthreads support will die with 2.6.16*.
