From: Benjamin Herrenschmidt Date: Mon, 4 Jun 2007 05:15:39 +0000 (+1000) Subject: [POWERPC] Disable broken PPC_PTRACE_GETFPREGS on 32 bits X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0b3d5c48a98f7bd2d38962f5a67b480ac5656fb9;p=openwrt%2Fstaging%2Fblogic.git [POWERPC] Disable broken PPC_PTRACE_GETFPREGS on 32 bits The handling of PPC_PTRACE_GETFPREGS is broken on 32 bits kernel, it will only return half of the registers. Since that call didn't initially exist for 32 bits kernel (added recently), rather than fixing it, let's just remove it.
