[PATCH v4 00/14] Introduce generic headers



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.

Patch related to delay.h [3] was sent separately.

This patch series is a pre-requisite for "Enable build of full Xen for RISC-V" 
[4].

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 <asm/random.h>
    [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 <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 07/29] xen/asm-generic: introduce stub header 
guest_atomics.h
         - [PATCH v1 10/29] xen/asm-generic: introduce stub header iommu.h
         - [PATCH v1 12/29] xen/asm-generic: introduce stub header pci.h 
because separate patch was sent [5]
         - [PATCH v1 14/29] xen/asm-generic: introduce stub header setup.h
         - [PATCH v1 15/29] xen/asm-generic: introduce stub header xenoprof.h 
because of [3].
         - [PATCH v1 16/29] xen/asm-generic: introduce stub header flushtlb.h
         - [PATCH v1 22/29] xen/asm-generic: introduce stub header delay.h 
because of [3]
         - [PATCH v1 23/29] xen/asm-generic: introduce stub header domain.h
         - [PATCH v1 24/29] xen/asm-generic: introduce stub header 
guest_access.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.
