This is meant to allow for different canary values per task. On ARM, GCC expects the canary value to be found in a global variable called __stack_chk_guard. So this variable has to be updated with the value stored in the task struct whenever a task switch occurs. Because the variable GCC expects is global, this cannot work on SMP unfortunately. So, on SMP, the same initial canary value is kept throughout, making this feature a bit less effective although it is still useful. One way to overcome this GCC limitation would be to locate the __stack_chk_guard variable into a memory page of its own for each CPU, and then use TLB locking to have each CPU see its own page at the same virtual address for each of them.

This introduces new symbols SOC_IMX1, SOC_IMX21 and SOC_IMX27. They are selected by the old symbols for now. There is no substitute for MACH_MX2 as most usages of MX2 only means MX21 + MX27 but not MX25. Later the choice about CPU and CPU family should go away and the individual machines should select the right SOC symbol. This is a precondition to support more than one SOC in a single kernel image.

This was done to match the original DNS-323 firmware which blinks during the boot process and sets the LED to solid when booting has completed. However, the downside of this behaviour is that it requires userland code to change the LED, even for those who don't care about the behaviour of the original firmware. Therefore, change it to solid again and let those who care about the original behaviour change the behaviour from userland.

According to an engineer from QNAP, the setting of MPP44 depends on the firmware rather than hardware. Presumably, this means that you could fake the MPP44 value by changing the boot loader.
