Backport upstream proposal for fix.

Fixes: br-m68k-68040-full failure.

I haven't found this in autobuild [1], there are just problems with
fanotify tests missing MAX_HANDLE_SZ, which are fixed in next version
(second patch).

Kind regards,
Petr

+Subject: [PATCH] cacheflush01: Rewrite into new API
+
+This syscall is currently (v5.9) supported on these architectures:
+arc, csky, mips, m68k, nds32, sh
+
+constants are missing for m68k, not sure if the testcase is valid for it.
+Untested.
+
+Test for __LTP__NR_INVALID_SYSCALL saves adding autotools check for
+<asm/cachectl.h>.
