Revision 88a7c26af8dab2f2d69f5a6067eb670694ec38c0 authored by Andy Lutomirski on 04 January 2015, 18:36:19 UTC, committed by Ingo Molnar on 09 January 2015, 10:12:28 UTC
On x86_64, at least, task_pt_regs may be only partially initialized in many contexts, so x86_64 should not use it without extra care from interrupt context, let alone NMI context. This will allow x86_64 to override the logic and will supply some scratch space to use to make a cleaner copy of user regs.
