[PATCH v2 00/15] Introduce generic headers

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

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.

Some headers are still arguable if they should be in asm-generic, and it wasn't 
a response so
I decided to leave headers for now and made some updates for them.

Some patches related to delay.h, pci.h and xenoprof.h were sent as separate 
patches: [3], [4]
and [5].

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
