From e090aa80321b64c3b793f3b047e31ecf1af9538d Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 8 Dec 2009 18:45:45 +0000 Subject: [PATCH] powerpc: Fix usage of 64-bit instruction in 32-bit altivec code e821ea70f3b4873b50056a1e0f74befed1014c09 introduced a bug by copying some 64-bit originated code as-is to be used by both 32 and 64-bit but this code contains a 64-bit ony "cmpdi" instruction. This changes it to cmpwi, which is fine since VRSAVE can only contains a 32-bit value anyway.
