From: Christoph Hellwig Date: Tue, 25 Nov 2008 07:10:03 +0000 (+0100) Subject: remove __ARCH_WANT_COMPAT_SYS_PTRACE X-Git-Tag: v2.6.28-rc7~57 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=96b8936a9ed08746e47081458a5eb9e43a751e24;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git remove __ARCH_WANT_COMPAT_SYS_PTRACE All architectures now use the generic compat_sys_ptrace, as should every new architecture that needs 32bit compat (if we'll ever get another). Remove the now superflous __ARCH_WANT_COMPAT_SYS_PTRACE define, and also kill a comment about __ARCH_SYS_PTRACE that was added after __ARCH_SYS_PTRACE was already gone.
