Subject: [Xen-devel] [PATCH v4 1/2] xen: switch pdx_init_mask to return uint64_t
Date: Mon, 17 Jun 2019 11:50:16 -0700	[thread overview]
Message-ID: <20190617185017.32661-1-sstabellini@kernel.org> (raw)
In-Reply-To: <alpine.DEB.2.21.1906171146440.2072@sstabellini-ThinkPad-T480s>

Also change srat_region_mask to uint64_t as it is used to store the
return value of pdx_init_mask. uint64_t is always greater or equal to
u64.
