mm/memblock.c: cast constant ULLONG_MAX to phys_addr_t
This fixes a warning shown when phys_addr_t is 32-bit int when compiling with clang: mm/memblock.c:927:15: warning: implicit conversion from 'unsigned long long' to 'phys_addr_t' (aka 'unsigned int') changes value from 18446744073709551615 to 4294967295 [-Wconstant-conversion] r->base : ULLONG_MAX; ^~~~~~~~~~ ./include/linux/kernel.h:30:21: note: expanded from macro 'ULLONG_MAX' #define ULLONG_MAX (~0ULL) ^~~~~ Link: http://lkml.kernel.org/r/20180319005645.29051-1-stefan@agner.ch Signed-off-by: Stefan Agner <stefan@agner.ch> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Cc: Michal Hocko <mhocko@suse.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Pavel Tatashin <pasha.tatashin@oracle.com> Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
