[PATCH] Kprobes- robust fault handling for i386

[Keshavamurthy, Anil S]

Prasanna,
	For better review comments, can you please split your patch
into following, currently finding it hard to follow the kprobes states.
1) [PATCH]Fault handling due to calling pre_handler
2) [PATCH]Fault handling due to calling post_handler
3) [PATCH]Fault handling due to single_stepping
4) [PATCH]Fault handling due to single_stepping reentrant probe

Patches 3 and 4 above are required only to support user probes,
so for now I think you can skip them.

Also another suggesting, rename the kprobes states to something more
meaning full. Say
KPROBE_IN_PRE_HANDLER - This states indicates we are calling pre_handler
KPROBE_IN_POST_HANDLER - This states indicates we are calling
post_handler
KPROBES_IN_SS - We are trying to single step
KPROBES_IN_REENTER_SS - We are trying to single step reentrant probes 
[...]


Thanks,
