v5.1.0-rc0 release

ppc patch queue 2020-06-26

Here's another pull request for qemu-5.1.  Not very much in this one,
just a handful of assorted minor fixes and cleanups.

I'm about to go on holiday for a couple of weeks, so this will be my
last PR before the freeze, and maybe the last for 5.1 at all.  If
there's some super important fix we need, Greg Kurz will handle it.

4.2.1

ppc patch queue 2020-05-27

Here's the next pull request for qemu-5.1.  It includes:
 * Support for the scv and rfscv POWER9 instructions in TCG
 * Support for the new SPAPR_LMB_FLAGS_HOTREMOVABLE flag, which
   provides a way for guests to know memory which should be removable
   (so the guest can avoid putting immovable allocations there).
 * Some fixes for the recently added partition scope radix translation
   in softmmu
 * Assorted minor fixes and cleanups

It includes one patch to avoid a clash with SELinux when using NVLink
VFIO devices.  That's not technically within the files under my
maintainership, but it is in a section of the VFIO quirks code that's
specific to the POWER-only NVLink devices, and has an ack from Alex
Williamson.
