Upstream commit 81c9d43f94870be66146739c6e61df40dc17bb64 was backported into the Red Hat Enterprise Linux 8 kernel tree, adding:
+ KERN_PANIC_PRINT=78, /* ulong: bitmask to print system info on panic */
This results in a misc/check-installed-headers-c test failure:
*** Obsolete types detected:
/usr/include/linux/sysctl.h: KERN_PANIC_PRINT=78, /* ulong: bitmask to print system info on panic */
In glibc upstream, this was fixed by this commit:

Use a proper C tokenizer to implement the obsolete typedefs test.
The test for obsolete typedefs in installed headers was implemented
using grep, and could therefore get false positives on e.g. “ulong”
in a comment. It was also scanning all of the headers included by
our headers, and therefore testing headers we don’t control, e.g.
Linux kernel headers.
This patch splits the obsolete-typedef test from
scripts/check-installed-headers.sh to a separate program,
scripts/check-obsolete-constructs.py. Being implemented in Python,
it is feasible to make it tokenize C accurately enough to avoid false
positives on the contents of comments and strings. It also only
examines $(headers) in each subdirectory--all the headers we install,
but not any external dependencies of those headers. Headers whose
installed name starts with finclude/ are ignored, on the assumption
that they contain Fortran. […]
