MLX5_GENERAL_OBJECT_TYPES types bitfield is 64-bit field.
Defining an enum for such bit fields on 32-bit platform results in below
warning.
./include/vdso/bits.h:7:26: warning: left shift count >= width of type [-Wshift-count-overflow]
^
./include/linux/mlx5/mlx5_ifc.h:10716:46: note: in expansion of macro ‘BIT’
MLX5_HCA_CAP_GENERAL_OBJECT_TYPES_SAMPLER = BIT(0x20),
^~~
Use 32-bit friendly BIT_ULL macro.
Fixes: 2a2970891647 ("net/mlx5: Add sample offload hardware bits and structures")

Or even better is to use "1ULL << 0x20" directly because we are not
including bits.h in this mlx5_ifc.h file.
Should I resend?
Thanks

I will change this and attach this patch to my PR of the SF support.
Thanks,

Looks like the SF discussion will not wind down in time to make this
merge window, so I think I'm going to take this in after all. Okay?
