    At once clean up formatting of the touched code and drop a stray loop

    x86/EPT: work around hardware erratum setting A bit
    
    Since commit 191b3f3344ee ("p2m/ept: enable PML in p2m-ept for
    log-dirty"), the A and D bits of EPT paging entries are set
    unconditionally, regardless of whether PML is enabled or not. This
    causes a regression in Xen 4.6 on some processors due to Intel Errata
    AVR41 -- HVM guests get severe memory corruption when the A bit is set
    due to incorrect TLB flushing on mov to cr3. The erratum affects the
    Atom C2000 family (Avoton).
    
    To fix, do not set the A bit on this processor family.

    credit1: fix tickling when it happens from a remote pCPU
    
    especially if that is also from a different cpupool than the
    processor of the vCPU that triggered the tickling.
    
    In fact, it is possible that we get as far as calling vcpu_unblock()-->
    vcpu_wake()-->csched_vcpu_wake()-->__runq_tickle() for the vCPU 'vc',
    but all while running on a pCPU that is different from 'vc->processor'.
    
    For instance, this can happen when an HVM domain runs in a cpupool,
    with a different scheduler than the default one, and issues IOREQs
    to Dom0, running in Pool-0 with the default scheduler.
    In fact, right in this case, the following crash can be observed:

    In this case, pCPU 7 is not in Pool-0, while the (Dom0's) vCPU being
    woken is. pCPU's 7 pool has a different scheduler than credit, but it
    is, however, right from pCPU 7 that we are waking the Dom0's vCPUs.
    Therefore, the current code tries to access csched_balance_mask for
    pCPU 7, but that is not defined, and hence the Oops.
    
    (Note that, in case the two pools run the same scheduler we see no
    Oops, but things are still conceptually wrong.)
    
    Cure things by making the csched_balance_mask macro accept a
    parameter for fetching a specific pCPU's mask (instead than always
    using smp_processor_id()).
