FYI, v17 will be based on tip:x86/debug. But note that, when run against that branch, it'll spit out a lot of these warnings: objtool: arch/x86/ia32/sys_ia32.o: __ex_table size not a multiple of 12 objtool: arch/x86/ia32/ia32_signal.o: __ex_table size not a multiple of 12 objtool: arch/x86/entry/common.o: __ex_table size not a multiple of 12 Those warnings mean it's expecting the new exception table format which was added in: 548acf19234d ("x86/mm: Expand the exception table logic to allow new handling options") So that commit is needed to avoid the warnings.
