Refresh patch "pci/switchtec: Don't use completion's wait queue" which was
already done as well in previous rt patchset, due to context changes in
4.19.116 caused by 12ce9fd7fc87 ("PCI/switchtec: Fix init_completion race
condition with poll_wait()").
Most of this is just resolving the same conflicts Salvatore already
handled locally.
"x86/ioapic: Don't let setaffinity unmask threaded EOI interrupt too
early" was refreshed instead of being dropped.
