ARM:

* Take care of faults occuring between the PARange and
   IPA range by injecting an exception
 
 * Fix S2 faults taken from a host EL0 in protected mode
 
 * Work around Oops caused by a PMU access from a 32bit
   guest when PMU has been created. This is a temporary
   bodge until we fix it for good.
 
 x86:
 
 * Fix potential races when walking host page table
 
 * Fix shadow page table leak when KVM runs nested
 
 * Work around bug in userspace when KVM synthesizes leaf
   0x80000021 on older (pre-EPYC) or Intel processors
 
 Generic (but affects only RISC-V):
 
 * Fix bad user ABI for KVM_EXIT_SYSTEM_EVENT
