Andrzej Hajda
andrzej.hajda at intel.com
Thu Jan 5 01:54:26 PST 2023
__xchg will be used for non-atomic xchg macro.
Signed-off-by: Andrzej Hajda <andrzej.hajda at intel.com>
Reviewed-by: Arnd Bergmann <arnd at arndb.de>
---
v2: squashed all arch patches into one
v3: fixed alpha/xchg_local, thx to lkp at intel.com
v4: adjusted indentation (Heiko)
