Subject: [RFC 04/11] Drivers: hv: Use HV_HYP_PAGE in hv_synic_enable_regs()
Date: Tue, 21 Jul 2020 09:41:28 +0800
Message-ID: <20200721014135.84140-5-boqun.feng@gmail.com> (raw)
In-Reply-To: <20200721014135.84140-1-boqun.feng@gmail.com>

Both the base_*_gpa should use the guest page number in Hyper-V page, so
use HV_HYP_PAGE instead of PAGE.
