Except in cases where compatibile implementations already exist (e.g. atomic.h and bitops.h), the newly added definitions are simple. The patch series is based on the following patch series: - [PATCH v6 0/9] Introduce generic headers [1] - [PATCH] move __read_mostly to xen/cache.h [2] - [PATCH] xen: move BUG_ON(), WARN_ON(), ASSERT(), ASSERT_UNREACHABLE() to xen/bug.h [3] - [XEN PATCH v2 1/3] xen: introduce STATIC_ASSERT_UNREACHABLE() [4] - [PATCH] xen/lib: introduce generic find next bit operations [5] Right now, the patch series doesn't have a direct dependency on [2] and it provides __read_mostly in the patch: [PATCH v3 26/34] xen/riscv: add definition of __read_mostly However, it will be dropped as soon as [2] is merged or at least when the final version of the patch [2] is provided.
