Intel Xeon Phi (KNC) MPSS modules for CentOS 7.5, 7.6, 7.7 and 7.8

The latest version (as of October 4th 2019) of the MPSS software stack for the first generation Intel Xeon Phi (aka KNC) is 3.8.6. Unfortunately, this version of the mpss stack does not support the newer RHEL/CentOS 7 kernels 3.10.0-862 (7.5), 3.10.0-957 (7.6), 3.10.0-1062 (7.7) and 3.10.0-1127 (7.8).
Even though Intel released version 3.8.5 well after RHEL 7.5 and 7.6 were released, and similarly, released version 3.8.6 after RHEL 7.7 was released, they state that this newer release only addresses critical customer issues and security hotfixes. Apparently, they find it important to address security issues in the MPSS stack and the KNC itself, but they do not care about security issues (SPECTRE anyone?) in the host operating system.

Therefore, I've grabbed the mpss-modules source tarball and patched it, so that it can be compiled for a 3.10.0-862, 3.10.0-957, 3.10.0-1062 or 3.10.0.1127 kernel. The resulting RPM and Source RPM (SRPM) can be download here, both for MPSS 3.8.6 and the previous 3.8.5 release. The same patch is used for the 3.10.0-862 and 3.10.0-957 kernels, but for the 3.10.0-1062 patch, the file micscif/micscif_select.c was added. For the 3.10.0-1127 patch, the file host/vmcore.c was added to work around an overlapping function name.
Note that the mpss-modules source tarballs for MPSS 3.8.4, 3.8.5 and 3.8.6 seem different, but a diff -r on the source trees resulted in zero difference.

Installation

You can install or upgrade the mpss-modules file using
  rpm -ivh https://www.nikhef.nl/~janjust/mpss/mpss-modules-3.10.0-1062.el7.x86_64-3.8.6-1.x86_64.rpm
Note
Normally, a weak-updates link is created when a module is installed, e.g.
  $ ls -al /lib/modules/3.10.0-862.6.3.el7.x86_64/weak-updates/
  total 4
  drwxr-xr-x 2 root root   20 Jul  5 16:58 .
  drwxr-xr-x 7 root root 4096 Jul  5 16:58 ..
  lrwxrwxrwx 1 root root   47 Jul  5 16:58 mic.ko -> /lib/modules/3.10.0-862.el7.x86_64/extra/mic.ko
This link is needed for the existing kernel to find the mic.ko file. If the module cannot be found after installing the mpss-modules RPM then you can simply create it yourself, or re-install the kernel RPM.
