This is the third and smallest of the SoC specific updates.
Changes include:
* SMP support for the Xilinx zynq platform
* Smaller imx changes
* LPAE support for mvebu
* Moving the orion5x, kirkwood, dove and mvebu platforms
to a common "mbus" driver for their internal devices.
It would be good to get feedback on the location of the "mbus"
driver. Since this is used on multiple platforms may potentially
get shared with other architectures (powerpc and arm64), it
was moved to drivers/bus/. We expect other similar drivers to
get moved to the same place in order to avoid creating more
top-level directories under drivers/ or cluttering up the
messy drivers/misc/ even more.

If this option is disabled, you allow userspace (root) access to all

access to this is obviously disastrous, but specific access can

When a user program crashes due to an exception, the kernel can

print a brief message explaining what the problem was. This is

sometimes helpful for debugging but serves no purpose on a

|
production system. Most people should say N here.
|

In addition, you need to pass user_debug=N on the kernel command
|
|
line to enable this feature. N consists of the sum of:
|
|
|
|
1 - undefined instruction events
|
|
2 - system calls

4 - invalid data aborts

8 - SIGSEGV faults

Semihosting enables code running on an ARM target to use

the I/O facilities on a host debugger/emulator through a

simple SVC call. The host debugger or emulator must have
|
|
semihosting enabled for the special svc call to be trapped

otherwise the kernel will crash.

This is known to work with OpenOCD, as well as
|

ARM's Fast Models, or any other controlling environment
|
|
that implements semihosting.
