[PATCH 0/2] x86/xen: Make idle tasks reliable

[Miroslav Benes]

The unwinder reports idle tasks' stack on XEN PV as unreliable which
complicates things for at least live patching. The two patches in the
series try to amend that by using similar approach as non-XEN x86 does.

However, I did not come up with a nice solution for secondary CPUs idle
tasks. The patch just shows the idea what should be done but it is an
ugly hack. Ideas are more than welcome.
