Signed-off-by: Oleksii Kurochko --- - [PATCH] move __read_mostly to xen/cache.h [2] 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. Considering that there is still no still final decision regarding patch [2] my suggestion is to merge RISC-V specific patch and just drop the changes in patch [2]. [2] https://lore.kernel.org/xen-devel/f25eb5c9-7c14-6e23-8535-2c66772b333e@suse.com/ --- Change in V8: - update the footer after Signed-off. --- Changes in V4-V7: - Nothing changed.
