Linus Torvalds 4ea3c64252 powerpc fixes for 5.18 #2 
- Fix KVM "lost kick" race, where an attempt to pull a vcpu out of the guest could be
    lost (or delayed until the next guest exit).
 
  - Disable SCV (system call vectored) when PR KVM guests could be run.
 
  - Fix KVM PR guests using SCV, by disallowing AIL != 0 for KVM PR guests.
 
  - Add a new KVM CAP to indicate if AIL == 3 is supported.
 
  - Fix a regression when hotplugging a CPU to a memoryless/cpuless node.
 
  - Make virt_addr_valid() stricter for 64-bit Book3E & 32-bit, which fixes crashes seen
    due to hardened usercopy.
 
  - Revert a change to max_mapnr which broke HIGHMEM.
