Description
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: nv: Drop bogus WARN for write to ZCR_EL2
It is entirely possible for a guest to write to the ZCR_EL2 sysreg alias
while in a nested context, as it is expected if FEAT_NV2 is advertised
to the L1 hypervisor.
Get rid of the bogus WARN which, since the hyp vectors were installed at
this point, has the effect of a hyp_panic...
