RH-Commit: [1/2] e514a00305cb0caab9d3acc0efb325853daa6d51

Upstream Status: RHEL-only
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2124757

Based on upstream commit e4082063e47e9731dbeb1c26174c17f6038f577f
("linux-headers: Update to v5.18-rc6"), but this is focusing on
the file linux-headers/linux/kvm.h only (since the other changes
related to the VFIO renaming might break some stuff).

(cherry picked from commit 71516db15469a02600932a5c1f0d4a9626a91193)
