[PATCH 0/4] livepatch: Add garbage collection for shadow variables

[Marcos Paulo de Souza <mpdesouza@suse.com>]

Hello reviewers,

These patches were originally created by Petr. The patches 3 and 4 were
originally one bigger patch but they are more easily reviewed split.

The patches 1 and 2 are code improvements.
Patch 3 adds a new struct called klp_shadow_type that combines the id, ctor and
dtor of a shadow variable. This patch is needed by patch 4.

Patch 4 adds the garbage collection.

Thanks for reviewing!
