mm/page_alloc: Revert pahole zero-sized workaround
Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to local_lock") folded in a workaround patch for pahole that was unable to deal with zero-sized percpu structures. A superior workaround is achieved with commit a0b8200d06ad ("kbuild: skip per-CPU BTF generation for pahole v1.18-v1.21"). This patch reverts the dummy field and the pahole version check. Fixes: dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to local_lock") Signed-off-by: Mel Gorman <mgorman@techsingularity.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
