Spotted from davej's blog: "So far, nothing really amazing, just a rebase to 2.6.22rc4, and some specfile jiggery-pokery to move away from using rpm's %patch directive to a hand crafted macro that allows patch application with -F1 (%patch won't let you pass arbitrary flags to patch(1), and the code in rpm to handle this made my eyes bleed). The benefits of patches with no fuzz should be obvious, the diffs end up applying in the right places. This has caused problems in the past to the extent where we had one bug that made the kernel not boot."
Very sad that a kernel developer's eyes bleed so much that he can't read "man 1 patch" anymore. UPSTREAM and the other fork too, fixed.
Fixed in next rawhide push by rpm 4.4.2.1-rc1
