This modifies the SMP trampoline and all of the associated code so
it can jump to a 64bit kernel loaded at an arbitrary address.
The dependencies on having an idenetity mapped page in the kernel

But I'm not sure this fix is correct or not. please review.

I would poke Eric Biederman(sp?) about this one. Maybe its even solved by
the MSI-enable-related patch he posted in the past

Each resource accounting container is supposed to

As part of this layer the write protect and card detect lines need to be read.
The method for determining the state of these lines will be board specific.

Ok, this is definitely faster on Core 2 as well, so "numbers talk,

Hmm.. It doesn't look *wrong*, but could you please
- split it up a bit (some of it is 100% obvious, ie the comment fixes)
- write an explanation for the individually split up patches
- not use attachments, but just make it i
That old ptrace check seems pretty questionable to me. I think what you
want is for the nommu world's get_user_pages/access_process_vm when called
with force=1,write=1 on a read-only MAP_PRIVATE page to do something more
morally similar to the mmu world's COW than it does now.
Thanks,

The number increases with the number numa nodes. We have had trouble with

Guarantee a mininum number of objects per slab
The number of objects per slab is important for SLUB because it determines
the number of allocations that can be performed without having to consult
per node slab lists. Add another boot option "min_objects=xx" that
