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>.
|
|
