Subject: [PATCH v9 02/14] KVM: Declare kvm_arch_flush_remote_tlbs() globally
Date: Fri, 11 Aug 2023 04:51:15 +0000 [thread overview]
Message-ID: <20230811045127.3308641-3-rananta@google.com> (raw)
In-Reply-To: <20230811045127.3308641-1-rananta@google.com>
There's no reason for the architectures to declare
kvm_arch_flush_remote_tlbs() in their own headers. Hence to
avoid this duplication, make the declaration global, leaving
the architectures to define only __KVM_HAVE_ARCH_FLUSH_REMOTE_TLBS
as needed.
