From e7084fd52ed71249ab2ce7a7d89d601c9d1f904c Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 5 Mar 2012 13:40:24 -0800 Subject: x32: Switch to a 64-bit clock_t clock_t is used mainly to give the number of jiffies a certain process has burned. It is entirely feasible for a long-running process to consume more than 2^32 jiffies especially in a multiprocess system. As such, switch to a 64-bit clock_t for x32, just as we already switched to a 64-bit time_t. clock_t is only used in a handful of places, and as such it is really not a very significant change. The one that has the biggest impact is in struct siginfo, but since the *size* of struct siginfo doesn't change (it is padded to the hilt) it is fairly easy to make this a localized change. This also gets rid of sys_x32_times, however since this is a pretty late change don't compactify the system call numbers; we can reuse system call slot 521 next time we need an x32 system call.
