    x86/percpu: Force INVALID_PERCPU_AREA into the non-canonical address region
    This causes accidental uses of per_cpu() on a pcpu with an 
    to result in a #GF for attempting to access the middle of the non-canonical
    virtual address region.
    This is preferable to the current behaviour, where incorrect use of

    implication in the context of PV guests.

commit ff239813b463309a7d41f9dacc84ac91e7aa9bd5
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>

    x86/idle: Fix get_cpu_idle_time()'s interaction with offline pcpus
    Checking for "idle_vcpu[cpu] != NULL" is insufficient protection against
    offline pcpus.  From a hypercall, vcpu_runstate_get() will determine "v !=
    current", and try to take the vcpu_schedule_lock().  This will try to look 
    per_cpu(schedule_data, v->processor) and promptly suffer a NULL structure
    deference as v->processors' __per_cpu_offset is INVALID_PERCPU_AREA.
    One example might look like this:
    Xen call trace:
       [<ffff82c4c0126ddb>] vcpu_runstate_get+0x50/0x113
       [<ffff82c4c0126ec6>] get_cpu_idle_time+0x28/0x2e
       [<ffff82c4c012b5cb>] do_sysctl+0x3db/0xeb8
       [<ffff82c4c023280d>] compat_hypercall+0xbd/0x116
    Pagetable walk from 0000000000000040:
     L4[0x000] = 0000000186df8027 0000000000028207
     L3[0x000] = 0000000188e36027 00000000000261c9
     L2[0x000] = 0000000000000000 ffffffffffffffff
    Panic on CPU 11:
    get_cpu_idle_time() has been updated to correctly deal with offline pcpus
    itself by returning 0, in the same way as it would if it was missing the
    idle_vcpu[] pointer.
    In doing so, XENPF_getidletime needed updating to correctly retain its
    described behaviour of clearing bits in the cpumap for offline pcpus.
    As this crash can only be triggered with toolstack hypercalls, it is not a
    security issue and just a simple bug.
