It looks like this is causing widespread build breakage in kselftest in
-next for arm64, there are *many* errors in the form:
In file included from test_signals_utils.c:14:
/build/stage/build-work/usr/include/asm/unistd.h:2:10: fatal error: unistd_64.h: No such file or directory
2 | #include <unistd_64.h>
| ^~~~~~~~~~~~~
which obviously looks like it's tied to the above but I've not fully
understood the patch/series yet. Build log at:
https://builds.sirena.org.uk/82d01fe6ee52086035b201cfa1410a3b04384257/arm64/defconfig/build.log
A bisect appears to confirm that it's this commit, which is in -next as
6e4a077c0b607c674536908c5b68f1c31e4e26ec.
