Another one reason to have them as generic is a simplification of adding support necessary to make a complete Xen build as it was/is being done in the patch series [1] and [2]. Also, instead of providing generic/stub headers, it was used "#ifdef CONFIG_* #include #endif" instead of providing empty headers. This patch series is a pre-requisite for "Enable build of full Xen for RISC-V" [3].

Update the patch series message as patch related to delay.h was merged. - Rebase on top of staging because half of the patches of the patch series were merged to staging branch. - Add A-by for some of the patches. - Add "depends on X86 || Arm" for CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS to be sure it won't be turned on by randconfig in CI. - Partly switch Arm and PPC to asm-generic/monitor.h. - Some other minor changes --- Changes in V4: - Update the cover letter message - Add Reviewed-by/Acked-by for patches: [PATCH v3 01/14] xen/asm-generic: introduce stub header paging.h [PATCH v3 03/14] xen/asm-generic: introduce generic hypercall.h [PATCH v3 04/14] xen/asm-generic: introduce generic header iocap.h [PATCH v3 05/14] xen/asm-generic: introduce stub header [PATCH v3 06/14] xen/asm-generic: introduce generic header percpu.h [PATCH v3 07/14] xen/asm-generic: introduce generalized hardirq.h [PATCH v3 08/14] xen/asm-generic: introduce generic div64.h header [PATCH v3 09/14] xen/asm-generic: introduce generic header altp2m.h [PATCH v3 10/14] xen/asm-generic: introduce stub header monitor.h [PATCH v3 11/14] xen/asm-generic: introduce stub header numa.h [PATCH v3 12/14] xen/asm-generic: introduce stub header softirq.h - Fix some code style and minor issues. - Use asm-generic version of device.h for Arm and PPC. --- Changes in V3: - Update the commit message of the cover letter. - Drop the following patch as it can be arch-specific enough: * [PATCH v2 09/15] xen/asm-generic: introduce generic header smp.h - Drop correspondent arch specific headers and use asm-generic version of a header. - Back to the patch series patches: * xen: ifdef inclusion of in * xen/asm-generic: ifdef inclusion of --- Changes in V2: - Update the commit message of the cover letter. - Drop the following patches because they are arch-specific or was sent as a separate patch: - xen/asm-generic: introduce stub header event.h - xen/asm-generic: introduce stub header spinlock.h -
