+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>.
