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.
Thanks!
