[Xen-devel] [RFC PATCH] Coverage support

[Frediano Ziglio <frediano.ziglio@xxxxxxxxxx>]

Updated set of patches for coverage.
Changes:
- implemented way of getting information
- use only 2 parameter in hypercall (still not sure it's better to use
  sysctl)
- use "coverage" for configuration option as suggested by Ian Campbell
- split header in include/public/gcov.h and include/xen/gcov.h to allow
  tools to include public header
- use weak to avoid defining compat_coverage_op

I manage to write 2 tools, one that call the new hypercall and dump the
blob in a file, one that split this file into required .gcda files. 
Both very hack ones and dirty but works and prove the hypervisor code is 
fine. Should I just send them anyway?

The forth patch allow to consume just 0 bytes if coverage is disabled.
