Subject: [PATCH v8 09/12] dax: Fix alloc_dax_region() compile warning
Date: Wed, 06 Nov 2019 17:43:37 -0800	[thread overview]
Message-ID: <157309101783.1579826.6555129802030578776.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <157309097008.1579826.12818463304589384434.stgit@dwillia2-desk3.amr.corp.intel.com>

PFN flags are (unsigned long long), fix the alloc_dax_region() calling
convention to fix warnings of the form:

>> include/linux/pfn_t.h:18:17: warning: large integer implicitly truncated to unsigned type [-Woverflow]
    #define PFN_DEV (1ULL << (BITS_PER_LONG_LONG - 3))
