83d435dd6e Fix example error_injection_tool
I got a "sched_setaffinity:: Invalid argument" error when using
err_injection_tool to inject error on a system with over 32 cpus.

Error information when injecting an error on a system with over 32 cpus:
$ ./err_injection_tool -i
/sys/devices/system/cpu/cpu0/err_inject//err_type_info
Begine at Tue Mar 26 11:20:08 2013
Configurations:
On cpu32: loop=10, interval=5(s) err_type_info=4101,err_struct_info=95
Error sched_setaffinity:: Invalid argument
All done

This because there is overflow when calculating the cpumask: the
type of (1<<k) is int, while mask[j] is unsigned long. When k > 31,
(1<<k) is truncated to ZERO, resulting in a unexpected cpumask.

01dd2fbf0d typo fixes
Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.

Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.

e1b43bd556 [IA64] Fix example error injection program
Progam accessed using /sys/devices/system/node/node0/cpu%d/err_inject/
This path only exists for CONFIG_NUMA=y systems.  Better to use
/sys/devices/system/cpu/cpu%d/err_inject/ which is available on all
systems.

bf62852784 [IA64] Itanium MC Error Injection Tool: Doc and sample application
This patch contains a documention and sample application. Since the sample
application has ~1000 lines of code, it might not be suitable in a kernel
documention in kenrel tree. If you think this is not good place to hold
the sample application, please let me know and I'm open to other choices
e.g. sourceforge etc.
