Linux 5.6 rc3

Fairly normal rc3 as far as I can tell. We've seen bigger, but we'veseen smaller ones too. Maybe this is slightly on the low side ofaverage at this time, which would make sense since this was a smallermerge window. Anyway, too much noise in the signal to be sure eitherway.The overall stats look fairly regular too: about 55% drivers (staging,sound, gpu, networking,  and usb look noticeable, with some noiseelsewhere). The bulk of the staging diff is actually the vsoc removal,so that's nice.Outside of drivers, we have the usual suspects: arch fixes (powerpc,s390, x86, but also a late csky update that I couldn't find it inmyself to worry about). Filesystems (ext4 and btrfs) and networking.And misc sprinkles of small fixes elsewhere.See the appended shortlog for details,             Linus
