I've just patched one of my older Core2 "Conroe", LFS-7.7, up to 4.4.110. It's an i686 system. With each minor-version patch "make oldconfig" was run. I saw no kernel config parameter for PAGE_TABLE_ISOLATION when I rebuilt the patched kernel. I can find no evidence it has been built into this kernel. I did get some hits for "kaiser" in the source code, arch/x86/mm/kaiser.c, and the mm/Makefile looks for CONFIG_PAGE_TABLE_ISOLATION. The make log I kept does not contain the string "kaiser", nor does /boot/System.map.
Any ideas? TIA.
