We want to report all system calls (even invalid ones) to the tracing layers, so check the NR only after we've notified. Signed-off-by: -

On Blackfin systems, the hardware single step exception triggers before the system call exception, so we need to save this info to process it later on. Otherwise, single stepping in userspace misses a few insns right after the system call. This is based a bit on the SuperH code added in commit 4b505db9. Reported-by:

We don't want to let user space modify the SYSCFG register arbitrarily as the settings are system wide (SNEN/CNEN) and can cause misbehavior. The only other bit here (SSSTEP) has proper controls via PTRACE_SINGLESTEP. Signed-off-by: -

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in <asm/ptrace.h> and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. 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. Signed-off-by:

This functions are implicitly called by core functions like cpu_relax(), and since those functions may be called early on before common code has initialized the per-cpu data area, we need to tweak the stats gathering. Now the statistics are maintained in common bss which makes these funcs safe to use as soon as the C runtime env is setup. Signed-off-by:

Since GCC doesn't support __builtin_frame_address(n) where n!=0, add our own function to walk the stack frame pointers. Signed-off-by:

Some userspace applications use this member in diagnosing crashes. It also makes some LTP tests pass (i.e. the Blackfin arch behaves more like everyone else). Signed-off-by:

When the kernel is executing out of parallel flash (XIP), we can't have the flash go into an erase/programming cycle, otherwise the instruction fetching steps fail and everything crashes. Signed-off-by:

The locking code in the address dumper needs to grab the mm's mmap_sem so that other CPUs do not get an inconsistent view. On UP systems this really wasn't a problem, but it is easy to trigger a race on SMP systems when another CPU removes a mapping. Signed-off-by:

During very early init, the stack pointer is given a slightly incorrect value (&init_thread_union). The value is later adjusted to the right one during early init (&init_thread_union + THREAD_SIZE), but it is used a few times in between. While the few functions used don't actually put things onto the stack (due to optimization), it's best if we simply use the right value from the start. Signed-off-by:
