Cover letter [patch-early-RFC 00/10] LTTng architecture dependent instrumentation

Hi,

Here is the architecture dependent instrumentation for LTTng. Not all architectures are supported, and some of them have missing instrumentation points.

The most complete should be :
x86_32, x86_64, powerpc, mips and arm.

It depends on the kernel trace thread flag patchset.

It instruments :
- traps/faults
- system calls
- kernel thread creation
- IPC calls
