I noticed that the struct mm_struct has following layout change after this patch.
Without the patch:
spinlock_t page_table_lock; /* 124 4 */
/* --- cacheline 2 boundary (128 bytes) --- */
struct rw_semaphore mmap_lock; /* 128 40 */ ----> in one cache line
struct list_head mmlist; /* 168 16 */
int mm_lock_seq; /* 184 4 */

With the patch:
spinlock_t page_table_lock; /* 180 4 */
struct rw_semaphore mmap_lock; /* 184 40 */ ----> cross to two cache lines
/* --- cacheline 3 boundary (192 bytes) was 32 bytes ago --- */
struct list_head mmlist; /* 224 16 */

This matches the profiling data:
18.92 +4.0 22.89 perf-profile.calltrace.cycles-pp.osq_lock.rwsem_optimistic_spin.rwsem_down_write_slowpath.down_write_killable.do_madvise
25.94 +4.8 30.73 perf-profile.calltrace.cycles-pp.rwsem_optimistic_spin.rwsem_down_write_slowpath.down_write_killable.do_madvise.__x64_sys_madvise
30.65 +5.3 35.96 perf-profile.calltrace.cycles-pp.rwsem_down_write_slowpath.down_write_killable.do_madvise.__x64_sys_madvise.do_syscall_64
31.48 +5.3 36.82 perf-profile.calltrace.cycles-pp.down_write_killable.do_madvise.__x64_sys_madvise.do_syscall_64.entry_SYSCALL_64_after_hwframe

Tested following change (which can make mmap_lock in one cache line with my
local kernel config):

diff --git a/include/linux/mm_types.h b/include/linux/mm_types.h
index de10fc797c8e..9c53f4e691a9 100644
--- a/include/linux/mm_types.h
+++ b/include/linux/mm_types.h
@@ -659,6 +659,7 @@ struct mm_struct {
spinlock_t page_table_lock; /* Protects page tables and some
* counters
*/
+ unsigned long pad;
/*
* With some kernel config, the current mmap_lock's offset
* inside 'mm_struct' is at 0x120, which is very optimal, as

It could make mmap_lock in one cache line:
spinlock_t page_table_lock; /* 180 4 */
long unsigned int pad; /* 184 8 */
/* --- cacheline 3 boundary (192 bytes) --- */
struct rw_semaphore mmap_lock; /* 192 40 */
struct list_head mmlist; /* 232 16 */
int mm_lock_seq; /* 248 4 */

And the regression is gone.
