Linux 5.12-rc4

From: Linus Torvalds
Date: Sun Mar 21 2021 - 18:41:06 EST

Very much an average rc4, possibly just a tad on the smaller side of average.

Nothing here particularly stands out. The diffstat looks a bit more
spread out than it perhaps normally would do, because of the removal
of the (never used) MODULE_SUPPORTED_DEVICE() thing that causes some
trivial line removal in various drivers, but not only did it never do
anything, it wasn't actually even all that common (ie it certainly
wasn't a "most drivers" kind of situation).

Anyway, drivers (sound, gpu, nvme, USB), some filesystem updates,
io-uring (signal fixes and cleanups), arch fixes (mostly RISC-V and
x86 kvm), and just random small things all over.

So I'll just tempt the fates and say that everything looks pretty
normal and this release seems to look good despite the rc1 hiccup,
