Hi,
congrats to Linux v5.11-rc7.
after commit 6342adcaa683 ("entry: Ensure trap after single-step on
system call return"):
$ git grep '\_TIF_SINGLESTEP' arch/x86/
arch/x86/include/asm/thread_info.h:#define _TIF_SINGLESTEP
(1 << TIF_SINGLESTEP)
Is this a leftover and can be removed (now)?

Some post-mortem:

module="drivers/net/ethernet/mellanox/mlx5/core/mlx5_core.ko"
Module has DW_ATE_unsigned_160 and DW_ATE_unsigned_1:
