Subject: [PATCH kvmtool 00/15] arm64: Handle PSCI calls in userspace

This is version 4 of the patch series, originally posted by Oliver [0]. Mostly
remains the same as v3, except for

 - Address Will's comment on the race between pause/resume - Patch 1
 - Rebase on to v6.17-rc7
 - Drop importing cputype.h, which was not used by the series
