Subject: [PATCH v6 5/7] KVM: x86: hyperv: valid_bank_mask should be 'u64'
Date:   Wed, 26 Sep 2018 19:02:57 +0200
Message-Id: <20180926170259.29796-6-vkuznets@redhat.com>
In-Reply-To: <20180926170259.29796-1-vkuznets@redhat.com>
References: <20180926170259.29796-1-vkuznets@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This probably doesn't matter much (KVM_MAX_VCPUS is much lower nowadays)
but valid_bank_mask is really u64 and not unsigned long.
