  x86/pci/xen: Disable PCI/MSI[-X] masking for XEN_HVM guests (2022-04-29 14:37:39 +0200)

----------------------------------------------------------------
- A fix to disable PCI/MSI[-X] masking for XEN_HVM guests as that is
solely controlled by the hypervisor

- A build fix to make the function prototype (__warn()) as visible as
the definition itself

- A bunch of objtool annotation fixes which have accumulated over time

- An ORC unwinder fix to handle bad input gracefully

- Well, we thought the microcode gets loaded in time in order to restore
the microcode-emulated MSRs but we thought wrong. So there's a fix for
that to have the ordering done properly

- Add new Intel model numbers

- A spelling fix
