linux/list.h: drop use of prefetch() 2025-06-18T14:05:04+00:00 Rasmus Villemoes ravi@prevas.dk 2025-05-07T12:12:43+00:00 c1c2b5c6a4c09fe57933b70ec6289795f732ac83 The use of prefetch() in these list helpers was dropped back in 2011 in linux (e66eed651fd1 ("list: remove prefetching from regular list iterators")). No arch in U-Boot defines any actual prefetch(), and as the referenced commit says, it's usually not a win anyway. Whole-sale sync of list.h is not really feasible, but we can synchronize the macros containing a prefetch() with their linux implementations as of v6.15-rc5, also importing the various helpers needed, e.g. list_is_head() and list_next_entry().

      hlist: drop the node parameter from iterators

Currently, there is only one "user" of any of these, namely in
fs/ubifs/super.c, but that actually uses the "new-style" form, and
is (obviously, or it wouldn't have built) inside #ifndef __UBOOT__.

Before adding actual users of these, import the version as of linux
v6.1-rc1, including the hlist_entry_safe() helper used by the new
