Subject: [PATCH v3 1/3] PCI: hv: Move hypercall related definitions into tlfs header
Date: Mon, 10 Feb 2020 11:39:51 +0800
Message-ID: <20200210033953.99692-2-boqun.feng@gmail.com> (raw)
In-Reply-To: <20200210033953.99692-1-boqun.feng@gmail.com>

Currently HVCALL_RETARGET_INTERRUPT and HV_PARTITION_ID_SELF are defined
in pci-hyperv.c. However, similar to other hypercall related
definitions, it makes more sense to put them in the tlfs header file.

Besides, these definitions are arch-dependent, so for the support of
virtual PCI on non-x86 archs in the future, move them into arch-specific
tlfs header file.
