The patch titled
cris arch-v10: use generic ptrace_resume code
has been removed from the -mm tree. Its filename was
cris-arch-v10-use-generic-ptrace_resume-code.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: cris arch-v10: use generic ptrace_resume code
From: Christoph Hellwig <hch@xxxxxx>
Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT and
PTRACE_KILL. This also makes PTRACE_SINGLESTEP return -EIO while it
previously succeeded despite not actually causing any kind of single
stepping.
Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which
it previously wasn't which is consistent with all architectures using the
modern ptrace code.
