Linux 5.7 rc2

Here we are, a week later, and rc2 looks pretty nice and calm. Ofcourse, it usually does that - people taking a breather after themerge window, and we may not have had enough time to see all theproblem reports yet.Everything continues to look fairly normal, with commit counts rightin the middle of what you'd expect for rc2. And most of the changesare tiny and don't look scary at all.In fact, about 30% of the patch is tooling, and even there a lot of itis because of one larger diff due to the x86 system call table beingre-synchronized with the main kernel side.Outside of that, we've got driver fixes (ethernet stands out, butthere's also other networking, GPU, sound, hwmon, i2c, clk..).  Andfilesystems (afs, btrfs, xfs, ext4, cifs, proc). And Documentation,networking and arch fixes. And small random things elsewhere.Some of the spread out noise is the replacement of zero-sized arrayswith flexible ones - we've had that come in through the varioussubsystems for a while now, and then Gustavo sent a pull request foranother random collection.Nothing that really should be seen as all that exciting. Which is allgood. The more noticeable one might be fixing the regression that wasdue to the EFI loaders not clearing the BSS section and us having lostthe workaround for that. That caused boot problems for some. Notperhaps exciting, but an example of the kind of solid (boring?) smallpedestrian things we've had.Shortlog appended so that you can scan the details if you want.
