v3: - Change commit message
    - Changed VIRTUAL_BUG_ON to ASSERT



Looking at the commit message you don't mention any renaming...

    - Dropped useless inner paranthesis for some macros

I don't understand why this suddenly appears in the code when you moved
away
in patch #1 in xen/numa.h.


Particularly MAX_NUMNODES required by this header file with this
patch changes for compilation.
Though I can include xen/numa.h here but xen/numa.h is including
asm/numa.h back.

I will add separate patch for this defines movement and drop from
this patch.


Why adding a separate patch? The code should not have been moved away in
patch #1 as you did.

In patch#1 , I have not moved MAX_NUMNODES. It is kept in xen/numa.h file
In this patch, when VIRTUAL_BUG_ON is changed to ASSERT, in asm-x86/numa.h,
it requires MAX_NUMNODES define. So I have moved it from xen/numa.h to
asm-x86/numa.h

I am sorry but looked at your patch #1. You moved NR_NODE_MEMBLKS in patch #1 from asm-x86/numa.h to xen/numa.h. And then you moved it again here.


So, I was thinking of  adding small patch to move both MAX_NUMNODES and
NR_NODE_MEMBLKS to asm-x86/numa.h

Or better, you can do in xen/numa.h:

#define MAX_NUMNODES ...
#define NR_NODE_...

#include <asm/numa.h>
