[PATCH v3 0/2] livepatch, arm64/module: Enable late module relocations.

Posted by Dylan Hatch 6 months, 3 weeks ago

Late relocations (after the module is initially loaded) are needed when
livepatches change module code. This is supported by x86, ppc, and s390.
This series borrows the x86 methodology to reach the same level of
support on arm64, and moves the text-poke locking into the core livepatch
code to reduce redundancy.

Dylan Hatch (2):
  livepatch, x86/module: Generalize late module relocation locking.
  arm64/module: Use text-poke API for late relocations.
