From c7f65094f7e2b8463a7c002e967e78db8f30468a Mon Sep 17 00:00:00 2001 From: hank Date: Tue, 20 Sep 2011 13:53:39 -0700 Subject: time: Change jiffies_to_clock_t() argument type to unsigned long commit cbbc719fccdb8cbd87350a05c0d33167c9b79365 upstream. The parameter's origin type is long. On an i386 architecture, it can easily be larger than 0x80000000, causing this function to convert it to a sign-extended u64 type. Change the type to unsigned long so we get the correct result.
