[PATCH v7 0/7] livepatch: Atomic replace feature

[Petr Mladek <pmladek@suse.com>]

The atomic replace allows to create cumulative patches. They
are useful when you maintain many livepatches and want to remove
one that is lower on the stack. In addition it is very useful when
more patches touch the same function and there are dependencies
between them.

Changes against v6:

  + used list_move when disabling replaced patches [Jason]
  + renamed KLP_FUNC_ORIGINAL -> KLP_FUNC_STATIC [Mirek]
  + used klp_is_func_type() in klp_unpatch_object() [Mirek]
  + moved static definition of klp_get_or_add_object() [Mirek]
  + updated comment about synchronization in forced mode [Mirek]
  + added user documentation
  + fixed several typos
