Subject: linux/list.h: drop fallback definition of prefetch()
X-Git-Tag: v2025.10-rc1~118^2~12^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1d19bbcb68280814952bdc18d7dec6d083b2c0ef;p=thirdparty%2Fu-boot.git

linux/list.h: drop fallback definition of prefetch()

None of the list helpers use prefetch() anymore, and no C code relies
on getting this definition from list.h. In any case, such an arch/cpu
specific thing does not belong in a header that just consists of cpp
helper macros.
