Subject: [PATCH 0/2] introduce kaslr_offset() and its users

There is already in-kernel code which computes the offset that has been 
used for kASLR -- that's dump_kernel_offset() notifier. As there is now a 
potential second user coming, it seems reasonable to provide a common 
helper that will compute the offset.

- Patch 1/2 introduces kaslr_offset() which computes the kASLR offset, and 
  converts dump_kernel_offset() to make use of it
- Patch 2/2 extends the - currently limited - functionality of 
  livepatching when kASLR has been enabled and is active

----------------------------------------------------------------

      x86: introduce kaslr_offset()
      livepatch: x86: make kASLR logic more accurate
