Increases the limit of NR_CPUS to 4096 and introduces a
boolean called "MAXSMP" which when set (e.g. "allyesconfig")
will set NR_CPUS = 4096 and NODES_SHIFT = 9 (512).
I've been running this config (4k NR_CPUS, 512 Max Nodes)
on an AMD box with 2 dual-cores and 4gb memory. I've also
successfully booted it in a simulated 2cpus/1Gb environment.

Increase stack size for the kernel bootloader decompressor. This is
needed to boot a kernel with NR_CPUS = 4096. I tested with 8k stack
size but that wasn't sufficient.

cool!
this depends on the cpumask changes to work correctly (i.e. to boot at
all), right?

Yes, it overflows the stack quite quickly without the cpumask changes.
I didn't do any testing to see what's the minimal set of changes.

I'm not really getting the point of MAXSMP - people should simply pick
their values, and when they want the maximum "(2-4096)" and "(1-15)"
already provide this information (except that your patch hides the
latter information from the user).
And with your patch, even with MAXSMP=y people could still set
NR_CPUS=7 and NODES_SHIFT=15 or whatever else they want...
More interesting would be why you want it to set NODES_SHIFT to
something less than the maximum value of 15. I'm getting the fact that
2^15 > 4096 and that 15 might be nonsensical high, but this sounds more
like requiring a patch to limit the range to 9?

I guess the main effect is that "MAXSMP" represents what's really
usable for an architecture based on other factors. The limit of
NODES_SHIFT = 15 is that it's represented in some places as a signed
16-bit value, so 15 is the hard limit without coding changes, not
an architecture limit.

This is the x86-specific Kconfig file that presents the x86 specific
limits to the users.
If NODES_SHIFT=15 is offered to the user although it's higher than the
current architecture limit on x86 then this is simply a bug that should
be fixed.

NODES_SHIFT also controls how many page flag bits are set aside for the
node number. If you limit x86_64 to 512 nodes then lets keep this at 9.

if I set NR_CPUS to 128 instead of 4096 it will be ok.

Hi Yinghai,
Thanks for the feedback! Would you send me your config file and
other details (like cpu type/mem size/etc.) and I'll attempt
to reproduce the failure.
(My problem is that only the AMD box is a real "workstation", the
Intel box is a dual quad-cpu server so it's really deficient in I/O.)
Thanks,
Mike

* [PATCH 0/2] NR_CPUS: increase maximum NR_CPUS to 4096

To: Ingo Molnar; +Cc: Thomas Gleixner, H. Peter Anvin, Andrew Morton, linux-kernel
* Increases the limit of NR_CPUS to 4096 and introduces a
boolean called "MAXSMP" which when set (e.g. "allyesconfig")
will set NR_CPUS = 4096 and NODES_SHIFT = 9 (512).
I've been running this config (4k NR_CPUS, 512 Max Nodes)
on an AMD box with 2 dual-cores and 4gb memory as well as an
Intel box with 4 single-core cpus and 8Mb. I've also
successfully booted it in a simulated 2cpus/1Gb environment.
Based on:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

+ sched-devel/latest .../mingo/linux-2.6-sched-devel.git
