    x86/msr: Disallow guest access to the RAPL MSRs
    
    Researchers have demonstrated using the RAPL interface to perform a
    differential power analysis attack to recover AES keys used by other cores 
in
    the system.
    
    Furthermore, even privileged guests cannot use this interface correctly, due
    to MSR scope and vcpu scheduling issues.  The interface would want to be
    paravirtualised to be used sensibly.
    
    Disallow access to the RAPL MSRs completely, as well as other MSRs which
    potentially access fine grain power information.
    
    This is part of XSA-351.

    x86/msr: fix handling of MSR_IA32_PERF_{STATUS/CTL}
    
    Currently a PV hardware domain can also be given control over the CPU
    frequency, and such guest is allowed to write to MSR_IA32_PERF_CTL.
    However since commit 322ec7c89f6 the default behavior has been changed
    to reject accesses to not explicitly handled MSRs, preventing PV
    guests that manage CPU frequency from reading
    MSR_IA32_PERF_{STATUS/CTL}.
    
    Additionally some HVM guests (Windows at least) will attempt to read
    MSR_IA32_PERF_CTL and will panic if given back a #GP fault:
    
      vmx.c:3035:d8v0 RDMSR 0x00000199 unimplemented
      d8v0 VIRIDIAN CRASH: 3b c0000096 fffff806871c1651 ffffda0253683720 0
    
    Move the handling of MSR_IA32_PERF_{STATUS/CTL} to the common MSR
    handling shared between HVM and PV guests, and add an explicit case
    for reads to MSR_IA32_PERF_{STATUS/CTL}.
    
    Restore previous behavior and allow PV guests with the required
    permissions to read the contents of the mentioned MSRs. Non privileged
    guests will get 0 when trying to read those registers, as writes to
    MSR_IA32_PERF_CTL by such guest will already be silently dropped.

    xen/arm: Always trap AMU system registers
    
    The Activity Monitors Unit (AMU) has been introduced by ARMv8.4. It is
    considered to be unsafe to be expose to guests as they might expose
    information about code executed by other guests or the host.
    
    Arm provided a way to trap all the AMU system registers by setting
    CPTR_EL2.TAM to 1.
    
    Unfortunately, on older revision of the specification, the bit 30 (now
    CPTR_EL1.TAM) was RES0. Because of that, Xen is setting it to 0 and
    therefore the system registers would be exposed to the guest when it is
    run on processors with AMU.
    
    As the bit is mark as UNKNOWN at boot in Armv8.4, the only safe solution
    for us is to always set CPTR_EL1.TAM to 1.
    
    Guest trying to access the AMU system registers will now receive an
    undefined instruction. Unfortunately, this means that even well-behaved
    guest may fail to boot because we don't sanitize the ID registers.
    
    This is a known issues with other Armv8.0+ features (e.g. SVE, Pointer
    Auth). This will taken care separately.
    
    This is part of XSA-351 (or XSA-93 re-born).
