Sean Christopherson d61a12cb9a KVM: selftests: Fix divide-by-zero bug in memslot_perf_test ... Check that the number of pages per slot is non-zero in get_max_slots() prior to computing the remaining number of pages. clang generates code that uses an actual DIV for calculating the remaining, which causes a #DE if the total number of pages is less than the number of slots. traps: memslot_perf_te[97611] trap divide error ip:4030c4 sp:7ffd18ae58f0 error:0 in memslot_perf_test[401000+cb000] Fixes: a69170c65a ("KVM: selftests: memslot_perf_test: Report optimal memory slots") Signed-off-by: Sean Christopherson <seanjc@google.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20221213001653.3852042-4-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		2022-12-27 06:00:46 -05:00
