Revision c45442055dfdeb265cc20c9eeaa9fd11a75fbf51 authored by Arnd Bergmann on 22 February 2016, 21:58:34 UTC, committed by Dan Williams on 24 February 2016, 01:17:20 UTC
A recent bugfix changed pfn_t to always be 64-bit wide, but did not
change the code in pmem.c, which is now broken on 32-bit architectures
as reported by gcc:
In file included from ../drivers/nvdimm/pmem.c:28:0:
drivers/nvdimm/pmem.c: In function 'pmem_alloc':
include/linux/pfn_t.h:15:17: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
#define PFN_DEV (1ULL << (BITS_PER_LONG_LONG - 3))
This changes the intermediate pfn_flags in struct pmem_device to
be 64 bit wide as well, so they can store the flags correctly.
