commit 2fc016c5bd8aad2e201cdf71b9fb4573f94775bd upstream.
Add macros for single bit definitions of a specific type. These are
similar to the BIT() macro that already exists, but with a few
exceptions:
1. The namespace is such that they can be used in uapi definitions.
2. The type is set with the _AC() macro to allow it to be used in
assembly.
3. The type is explicitly specified to be UL or ULL.
