Some headers are common between several architectures, so the current patch series
provide them.
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 <asm/*.h> #endif" instead of providing empty headers.
This patch series is a pre-requisite for "Enable build of full Xen for RISC-V" [3].

Changes in V9:
- Drop the patch "[PATCH v8 1/7] automation: ensure values in EXTRA_FIXED_RANDCONFIG
are separated by new line" as better solution was suggested.
- introduce new follow-up patch for "xen/asm-generic: introduce generic device.h"
( it can be merged with patches 4,5 of this patch series ).
- All other changes please find in revision log to a patch.
---
Changes in V8:
- Add Acked-by Acked-by: Tamas K Lengyel <tamas@tklengyel.com> for patches:
[PATCH v7 4/7] xen/asm-generic: ifdef inclusion of <asm/mem_access.h>
[PATCH v7 3/7] xen/asm-generic: introduce stub header monitor.h
- Update the commit messages for patches:
[PATCH v7 5/7] xen/asm-generic: introduce generic device.h
[PATCH v7 6/7] xen/arm: switch Arm to use asm-generic/device.h
- Drop #ifdef HAS_PCI in asm-generic/device.h to be consistent with other pci-related
things in the header.
- Code styles fixes.
---
Changes in V7:
- The following patches were dropped because of rebasing as they were merged
to staging:
- [PATCH v6 3/9] xen/asm-generic: introduce generic div64.h header
- [PATCH v6 6/9] xen/asm-generic: introduce stub header softirq.h
- [PATCH v6 7/9] xen: ifdef inclusion of <asm/grant_table.h> in <xen/grant_table.h>
- [PATCH v6 8/9] xen/asm-generic: ifdef inclusion of <asm/mem_access.h>
- [PATCH v6 5/9] xen/asm-generic: introduce stub header numa.h was dropped becaus of
the patch: "[PATCH v2] NUMA: no need for asm/numa.h when !NUMA"
- Drop definition of arch_monitor_domctl_event for PPC.
- define arch_monitor_domctl_event in asm-generic/monitor.h.
- Add "define HAS_ARCH_MONITOR_DOMCTL_EVENT" in arm/.../monitor.h as it has arch
specific implementation.
- keeping DEVICE_PCI_HOSTBRIDGE available for every build based on the reply:
https://lore.kernel.org/xen-devel/926a5c12-7f02-42ec-92a8-1c82d060c710@xen.org/
- add comment above enum device_type.h with explanation about DEV_TYPE_MAX.
- drop #ifdef HAS_PCI around "(device_get_class(dev) == DEVICE_PCI_HOSTBRIDGE))" in ARM code.
- separate patch "[PATCH v6 9/9] xen/asm-generic: introduce generic device.h" into 3 patches.
---
Changes in V6:
- Fix the build script to work properly with EXTRA_FIXED_RANDCONFIG.
- Introduce separate randconfig yaml with fixed configs for RISC-V.
- Disable CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS for PPC and RISC-V.
- Remove change in Kconfig/common for CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS.
- Rebase on top of the latest staging.
---
Changes in V5:
- 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:

---
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 <asm/grant_table.h> in <xen/grant_table.h>
* xen/asm-generic: ifdef inclusion of <asm/mem_access.h>
---
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
- [PATCH v1 03/29] xen/asm-generic: introduce stub header cpufeature.h

- [PATCH v1 25/29] xen/asm-generic: introduce stub header irq.h ( probably not so generic as I expected, I'll back to it if it will be necessary in the future )
- [PATCH v1 28/29] xen/asm-generic: introduce stub header p2m.h ( probably not so generic as I expected, I'll back to it if it will be necessary in the future )
- For the rest of the patches please look at changes for each patch separately.
