What should happen is:

Thanks very much for the explanation, hopefully I have enough material to fly on
my own now.

Now, when you get the fault inside arm_copy_from_user(), you can
print the DACR value saved at the time the fault was generated by
printing the word above struct pt_regs on the stack - add to
arch/arm/mm/fault.c:do_DataAbort():

if (addr == 0xbf00202c) printk("DACR=0x%08x\n", *(u32 *)(regs + 1));

before the "if (!inf->fn(addr, fsr & ~FSR_LNX_PF, regs))" line.
That'll tell us what the DACR register was when we saved it.

If it isn't 0x75, then the next part of the puzzle is going to be
working out why it isn't.

It's 0x55. I'll track down how this happens, there are not that many places
where DACR is touched, and I'm in a very controlled environement, so I can
cunningly place JTAG breakpoints and watch DACR.

I'll report once I have a better idea what is happening, that might take me a
couple of days given that most of my workforce is available on weekends only.

Thanks again for the free lesson.
