very nice!

could we please split this up into several, gradual steps that bring 
setup_32.c and setup_64.c to exactly the same content - where the final 
patch just renames arch/x86/kernel/setup_32.c to arch/x86/kernel/setup.c 
and deletes arch/x86/kernel/setup_64.c ?

it would still result in exactly the same end result - but is much more 
bisectable (and reviewable, etc.). A bit like how arch/x86/mm/ioremap.c 
or arch/x86/mm/pageattr.c was unified.

maybe it can be done in less than 10 patches - but it guess it should be 
rather something in the neighborhood of 20 patches. Changes like this:

-       /*
-        * NOTE: before this point _nobody_ is allowed to allocate
-        * any memory using the bootmem allocator.  Although the
-        * allocator is now initialised only the first 8Mb of the kernel
-        * virtual address space has been mapped.  All allocations before

-        * variant (which allocates DMA'able memory) and care must be taken
-        * not to exceed the 8Mb limit.
-        */

should be in a separate patch - you removed this restriction from the 
x86 architecture via your earlier patches, so the removal of the comment 
comes from that (and deserves a separate commit), not purely from the 
mechanic unification in the end.

other changes like this:

-#ifdef CONFIG_X86_FIND_SMP_CONFIG
+#if defined(CONFIG_X86_FIND_SMP_CONFIG) && defined(CONFIG_X86_32) || \
+    defined(CONFIG_X86_MPPARSE) && defined(CONFIG_X86_64)

here you fix coding style:

-        /*
-         * Parse SRAT to discover nodes.
-         */
-        acpi_numa_init();
+       /*
+        * Parse SRAT to discover nodes.
+        */
+       acpi_numa_init();

etc. etc. You do a lot more very useful work than the plain single 
unification patch you sent tells us - all these changes should be split 
up.

[ and in the unlikely event of there being a bug somewhere in this 1600
  lines patch, a splitup is also useful for finding bugs :-) ]

OK,  someone (Mike Triavis) already stole setup.c for X86_NUMA.

You need to change that setup.c to other name. or split it away...

hm, that change was supposed to be the seed of a unification. So if it 
actually hinders you, feel free to move it to a different file. 
Obviously it is setup_32.c and setup_64.c that should be unified into 
setup.c.

One thing I was trying to do was to merge more stuff from setup_32/64 into
setup.c.  Unfortunately, there was some test failures on i386 that I did not
have time to debug.  But the file existed before my time. ;-)

Why does the current setup.c need to be renamed and not simply add the merged
changes into it?  

Thanks,
Mike

Ingo want make setup_32.c have everything (in 10 patches), and then
rename setup_32.c to setup.c and delete setup_64.c

will move numa related to setup_numa.c or numa.c

FWIW, I personally would like to see initialization-only code moved out 
of arch/x86/kernel at some point.  Right now "kernel" is a catch-all, in 
particular, it mixes drivers, runtime core code, and initialization code.

Did you CC: this to me to indicate that "x86_64: replace end_pfn with 
num_physpages" conflicts massively with this patch?  Fortunately I don't 
depend on it, so I don't mind much.

How does "max_pfn" differ from "num_physpages"?  Should one of them go 
as well?

64bit setup_arch assign num_physpages with end_pfn...

and max_pfn is defined in linux/bootmem.h
num_physpages  is defined in linux/mm.h

I posted a patch to remove end_pfn and replace it with num_physpages 
everywhere, which obviously clashed badly with your patch ;)

Do they contain separate values?  Do they mean different things?

32bit has max_pfn, max_low_pfn, max_pfn_mapped...and min_low_pfn.

x86 64 bit that they are same. num_phypages = max_pfn
32 bit when HIGHMEM=y, it is same.num_phypages = max_pfn
         when HIGHMEM=n, num_phypages = max_low_pfn

yeah, wanted to notify you, in case you were wondering about interaction 
in this area :)
