From 48edd768850825a4d01e5e5e737122333fc55cdf Mon Sep 17 00:00:00 2001 From: Petr Vorel Date: Fri, 2 Oct 2020 21:29:58 +0200 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 .
