+[AARCH64] GP bit (BTI) lost during two stages translation
+Description of problem:
+I noticed that the BTI faults were not reported.
+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.
