These do not meet stable criteria afaict: (3-5... I see this is
probably security bug; it would be good to mention in the preparation
patches what is going on because otherwise it is tricky to understand).

?? 03/72] mm: make page ref count overflow check tighter and m -- not sure description is good enough; preparation for later changes?
?? 04/72] mm: add try_get_page() helper function -- adds unused function
?? 05/72] mm: prevent get_user_pages() from overflowing page r -- over
100 line limit and depedns on previous patches. get_gate_page() change
not in -rc?.. it is in -next.
?? 08/72] s390: limit brk randomization to 32MB -- dunno, english is bad. It explains 1GB is a problem, but then it goes to 32MB?
?? 23/72] serial: ar933x_uart: Fix build failure with disabled -- this is not minimal fix; tricky to verify
?? 30/72] usb: gadget: net2272: Fix net2272_dequeue() -- dunno. "Only compile tested". Do we believe someone actually tested it before it went to stable?
?? 35/72] net: ks8851: Delay requesting IRQ until opened -- this fixes cosmetic problem in dmesg, not a serious bug.
?? 43/72] ARM: dts: imx6qdl: Fix typo in imx6qdl-icore-rqs.dts -- enables support for faster mmc on i.mx6. Not sure it qualifies as serious bug?
?? 46/72] net: xilinx: fix possible object reference leak -- patch to fix it up.
?? 58/72] leds: trigger: netdev: fix refcnt leak on interface -- cleanups with a fix in one package
?? 70/72] ptrace: take into account saved_sigmask in PTRACE{GE -- so
GETSIGMASK returns wrong mask to userspace. ... but does it cause any
problems and is there anyone relying on old behaviour?
