Subject: [PATCH] KVM: X86: Use the common definition - 'GPA_INVALID' for X86
Date:   Fri,  9 Dec 2022 10:36:22 +0800
Message-Id: <20221209023622.274715-1-yu.c.zhang@linux.intel.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

KVM already has a 'GPA_INVALID' defined as (~(gpa_t)0) in
kvm_types.h, and it is used by ARM and X86 xen code. We do
not need a replicated 'INVALID_GPA' for X86 specifically.
Just replace it with the common one.

Tested by rebuilding KVM.

No functional change intended.
