Using OABI, the call to put_user in do_signal can fail causing the
calling app to hang.

The solution is to check if put_user fails and force the app to
seg fault in that case.

Tested with multiple sleeping apps/threads (using the nanosleep syscall)
and suspend/resume.

I stumbled over two small things regarding the .index field assignment
in the dynamically created cpu frequency tables for pxa2xx and pxa3xx.

Even though that doesn't currently cause any problem, it should still be
fixed in case the logic in the CPUFREQ core changes.

d451564 broke ARM by requiring KM_IRQ_PTE, KM_NMI and KM_NMI_PTE to
always be defined.  Solve this by providing invalid definitions for
these constants, but only if CONFIG_DEBUG_HIGHMEM is enabled.
