Change log
v6 -> v7
- Divide into two patches to make a code review easier.
Summery of each patch is as follows.
- Patch 1/2
- Add an irq_vector tracing infrastructure.
- Create idt_table for tracing. It is refactored to avoid duplicating
existing logic.
- Dupli

Hello Mister Mattock.
I hope this email will not bother you. It's about the eGalax
Touchscreen driver you modify more or less recently.
I try to use it on a archos 9 tablet PC, with tricks from that link and others:

[Purpose of this patch]
As Vaibhav explained in the thread below, tracepoints for irq vectors
are useful.
http://www.spinics.net/lists/mm-commits/msg85707.html
The current interrupt traces from irq_handler_entry and irq_handler_exit
provide when an interrupt is handled. They provide good data
[Issue]
Currently, irq vector handlers for tracing are just
copied non-trace handlers by simply inserting tracepoints.
It is difficult to manage the codes.
[Solution]
This patch shares common codes between non-trace and trace handlers
as follows to make them manageable and readable.
Non-trace

Hello,
I have a user with uid=1000 that runs a process, let's say with pid 42.
If I do a readlink on /proc/42/exe from another process run by that
same user,
it reads the link correctly.
If root calls readlink on that same link, it works correctly.
The problem is that I have another process t
