[PATCH 0/1] replace lttng with lttng-2.0 in core-tools-profile, v2

[tom.zanussi]

From: Tom Zanussi <tom.zanussi@intel.com>

The current packagegroup-core-tools-profile pulls in 'legacy' lttng
packages, which are useless with the linux-yocto kernels since those
don't include lttng support.

lttng-2.0 does seem to work, if the patch for lttng-modules that I just
sent to oe-core is applied as well (lttng-modules: update SRCREV and
remove is_compat_task).

I've only done minimal testing using qemux86, but even so it should at
least be better than the curent situation.

Sending this patch to poky instead of oe-core since it could be that
legacy lttng is what's being used by most people, but it clearly doesn't
work for yocto.

v2: the current lttng2 recipes don't build for mips.  From the recipes:

  # Due to liburcu not building for MIPS currently this recipe needs to
  # be limited also.
  # So here let us first suppport x86/arm/powerpc platforms now.

NOTE: this patch requires the accompanying oe-core patch to be applied
as well:

[PATCH 1/1] packagegroup-core-tools-profile: replace 'legacy' lttng with lttng 2.0

[tom.zanussi]

From: Tom Zanussi <tom.zanussi@intel.com>

packagegroup-core-tools-profile currently pulls in the 'legacy' lttng
packages, which are useless without legacy lttng support in the kernel.

This makes packagegroup-core-tools-profile pull in the lttng 2.0
packages instead, which don't need any kernel modifications to work.
