From 59bab33a4f57f886c5f8a4d1f2bed728ec185d16 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 3 Aug 2022 13:47:33 +0200 Subject: powerpc/ppc-opcode: Fix PPC_RAW_TW() PPC_RAW_TW() is erroneously defined with base code 0x7f000008 instead of 0x7c000008. That's invisible because its only user is PPC_RAW_TRAP() which is 0x7fe00008, but fix it anyway to avoid any risk of future bug.
