For the actual patches, I will refer you to the following Linux Kernel
mailing list post --

https://lkml.org/lkml/2017/12/4/709

Please note that in the Red Hat distributions' kernel (and, thus,
CentOS, Scientific Linux et al) the configuration option appears as
CONFIG_KAISER=y. That is a result of Red Hat applying the earliest
viable set of patches to their kernels. For the latest, current,
kernel sources from kernel.org the configuration option appears as
CONFIG_PAGE_TABLE_ISOLATION=y, as will be seen from the above mailing
list post. I would like to stress that from an end-user's viewpoint,
CONFIG_KAISER=y is equivalent to CONFIG_PAGE_TABLE_ISOLATION=y.

The namespace change came about as "Several people including Linus
requested to change the KAISER name." and some potential candidates
were offered under point (2) of the above mailing list post.
