livepatch: doc: remove the limitation for schedule() patching

2017-01-11T01:33:39Z

The Limitations section of the documentation describes the impossibility to livepatch anything that is inlined to __schedule() function. This had been true till 4.9 kernel came. Thanks to commit 0100301bfdf5 ("sched/x86: Rewrite the switch_to() code") from Brian Gerst there is __switch_to_asm function now (implemented in assembly) called properly from context_switch(). RIP is thus saved on the stack and a task would return to proper version of __schedule() et al. functions. Of course __switch_to_asm() is not patchable for the reason described in the section. But there is no __fentry__ call and I cannot imagine a reason to do it anyway. Therefore, remove the paragraphs from the section.

livepatch: Add some basic livepatch documentation

2016-04-27T20:01:32Z

livepatch framework deserves some documentation, definitely. This is an attempt to provide some basic info. I hope that it will be useful for both LivePatch producers and also potential developers of the framework itself.
