Linux 4.11 rc2

As usual, the week after rc1 tends to be fairly quiet when people arestill looking for bugs and taking a breather after the merge window.But we've got a healthy number of fixes in, and there's somecleanup/prep patches for the upcoming 5-level page table support thatI took after the merge window just to make the next merge windoweasier.There's also a (small) late random driver update.But most of it is just fixes, with arch and drivers being the bulk ofit (powerpc and i915 stand out, respectively) but with a noticeablecomponent elsewhere (mm patches mainly through Andrew, some fsupdatres, radix tree test updates etc).Shortlog appended with details, go forth and test. I think we're infine shape for this stage in the development kernel, it shouldn't beparticularly scary to just say "I'll be a bit adventurous and test anrc2 kernel". Yes, it's early rc time still, but go on, help us makesure we're doing ok..                   Linus
