From 0ad50c3896afbb3c103409a18260e601b87a744c Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 17 Dec 2012 16:01:45 -0800 Subject: compat: generic compat_sys_sched_rr_get_interval() implementation This function is used by sparc, powerpc tile and arm64 for compat support. The patch adds a generic implementation with a wrapper for PowerPC to do the u32->int sign extension. The reason for a single patch covering powerpc, tile, sparc and arm64 is to keep it bisectable, otherwise kernel building may fail with mismatched function declarations.
