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:

Use the common attribute rather than setting the section name directly. The common linker script defines expect the newer naming. Signed-off-by:

Since we are now discarding .exit.text at runtime instead of link time, we need to place all .text sections ahead of the .data sections. Otherwise, a really large attached initramfs may cause link errors as it pushes the PC relative relocations behind the limits of the Blackfin ISA (~16meg). The instructions in the .exit.text are unable to call back into the .text sections leading to a link failure. Signed-off-by:

SMP systems require per-cpu local clock event devices in order to enable HRT support. One a BF561, we can use local core timer for this purpose. Originally, there was one global core-timer clock event device set up for core A. To accomplish this feat, we need to split the gptimer0/core timer logic so that each is a standalone clock event. There is no requirement that we only have one clock event source anyways. Once we have this, we just define per-cpu clock event devices for each local core timer. Signed-off-by:
