    i386: Add Icelake-Server-v6 CPU model with 5-level EPT support
432cb7
432cb7
    Windows 11 with WSL2 enabled (Hyper-V) fails to boot with Icelake-Server
432cb7
    {-v5} CPU model but boots well with '-cpu host'. Apparently, it expects
432cb7
    5-level paging and 5-level EPT support to come in pair but QEMU's
432cb7
    Icelake-Server CPU model lacks the later. Introduce 'Icelake-Server-v6'
432cb7
    CPU model with 'vmx-page-walk-5' enabled by default.
