Subject: [PATCH v1 1/1] lib/string: add ULL suffix to the constant definition
Date: Tue, 10 Nov 2015 14:23:38 +0200 [thread overview]
Message-ID: <1447158218-34479-1-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
8-byte constant is too big for long and compiler complains about this.
lib/string.c:907:20: warning: constant 0x0101010101010101 is so big it is long
Append ULL suffix to explicitly show its type.
