That's because the GP (guarded page) information is lost during the two stages translation in get_phys_addr_twostage(). The "guarded" information is correctly retrieved by the first call to get_phys_addr_nogpc() but overwritten by the the second call to get_phys_addr_nogpc(). The call to combine_cacheattrs() copies cacheattrs1.guarded but this field is never modified. The attached patch fixes the issue for me.
