This should be:
NOTE_KERNELCAP_BEGIN(1, 1)
NOTE_KERNELCAP(0, "nosegneg")
NOTE_KERNELCAP_END
i.e. 1->0 in the "bit" member. (Note the ld.so.conf.d file must have the
matching bit number for ldconfig-based

It's not the indirection count that I worry about.

Yes he has already explained it and I am well aware of the difficulties

What lookup would you need to do? On x86_64 even the TLB use is
hidden by the existing 2M entries for 1-1 mappings.
Or are you
