    xen: arm: Correctly handle do_sysreg exception injection from 64-bit 
userspace
    
    The do_sysreg case was missing a return, so it would increment PC and
    inject the trap to the second instruction of the handler.
    
    This is CVE-2014-5148 / XSA-103.

    xen: arm: Handle traps from 32-bit userspace on 64-bit kernel as undef
    
    We are not setup to handle these properly. This turns a host crash
    into a trap to the guest kernel which will likely result in killing
    the offending process.
    
    This is part of CVE-2014-5147 / XSA-102.

    xen: arm: Correctly handle exception injection from userspace on 64-bit.
    
    Firstly we must be prepared to propagate traps from 32-bit userspace even 
for
    64-bit guests, so wrap the existing inject_undef??_exception into
    inject_undef_exception and use that when injecting an undef exception. The
    various other exception cases (aborts etc) already do this.
    
    Secondly when injecting the trap we must pick the correct exception vector
    depending on whether the source of the trap was 32-bit EL0, 64-bit EL0 or 
EL1.
    
    This is part of CVE-2014-5147 / XSA-102.

    xen: arm: handle AArch32 userspace when dumping 64-bit guest state.
    
    A 64-bit guest can still be in 32-bit mode when running userspace,
    handle this case by dumping the correct 32-bit state.
    
    Note that on ARM it is not possible to change mode without the help
    of the next exception level, hence there is no way a 64-bit guest can
    be running in 32-bit kernel modes.
    
    This is part of CVE-2014-5147 / XSA-102.

    x86/paging: make log-dirty operations preemptible
    
    Both the freeing and the inspection of the bitmap get done in (nested)
    loops which - besides having a rather high iteration count in general,
    albeit that would be covered by XSA-77 - have the number of non-trivial
    iterations they need to perform (indirectly) controllable by both the
    guest they are for and any domain controlling the guest (including the
    one running qemu for it).
    
    This is CVE-2014-5146 / XSA-97.
