Subject: [PATCH 09/10] KVM: selftests: Make set_memory_region_test common to all architectures
Date: Fri, 10 Apr 2020 16:17:06 -0700	[thread overview]
Message-ID: <20200410231707.7128-10-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200410231707.7128-1-sean.j.christopherson@intel.com>

Make set_memory_region_test available on all architectures by wrapping
the bits that are x86-specific in ifdefs.  All architectures can do
no-harm testing of running with zero memslots, and a future testcase
to create the maximum number of memslots will also be architecture
agnostic.
