Kernel prepatch 4.4-rc7

Noting that "there is no rest for kernel developers," Linushas released the 4.4-rc7 prepatch. Still,it seems he plans to allow for a bit of rest in the near future: "Iexpect more of the same for next week, when I'd almost certainly ready tojust release the final 4.4, but will probably do an rc8 just to not openthe merge window while people are still recovering from theholidays."
