Ping again. This patchset is adding a generic infrastructure for luks support in crash dumping, and it adds the support in x86 ARCH. Since the x86 related change is only located in kdump only files, won't impact other x86 codes. Could you consider pick this into your tree? And by the way, this is a kdump only fix, not related to KHO (Kexec HandOver) which David suggested to adapt to earlier. Explained it here to remove misunderstanding.
