  Revert "powerpc: Set max_mapnr correctly" (2022-04-07 08:54:35 +1000)

- ------------------------------------------------------------------
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.

Thanks to: Christophe Leroy, Fabiano Rosas, Kefeng Wang, Nicholas Piggin, Srikar Dronamraju.
