Subject: list, perf: fix list_force_poison() build regression
In file included from
/home/sfr/next/next/tools/include/linux/list.h:5:0,
from arch/../util/map.h:6,
from arch/../util/event.h:8,
from arch/../util/debug.h:7,
from arch/common.c:4:
include/linux/list.h: In function 'list_force_poison':
include/linux/list.h:123:56: error: unused parameter 'entry' [-Werror=unused-parameter]
static inline void list_force_poison(struct list_head *entry)
perf does not like the empty definition of list_force_poison. For
simplicity just switch to list_del in the non-debug case.
Fixes "mm, dax, pmem: introduce {get|put}_dev_pagemap() for dax-gup" in
-next.
