From bb2c458b8b8c8a53f65b78051d22a0f13d53abcb Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Sun, 28 Nov 2010 06:33:14 +0000 Subject: [PATCH] powerpc: Update compat_arch_ptrace Update compat_arch_ptrace to follow recent changes in PTRACE_GET_DEBUGREG and the addition of PPC_PTRACE_{GETHWDBGINFO|{SET|DEL}HWDEBUG}. The latter three can be forwarded to arch_ptrace unchanged.
