Hi,

I've split the main x86/mm/kmemcheck.c file and made a subdirectory of many
files instead.

I have included the diffstat below, but I think the patch itself is too big
for the mailing list. It can instead be viewed at:

http://www.kernel.org/pub/linux/kernel/people/vegard/patc...

The RFC part: Is this a good thing to do? I personally hate the 4000-line
files that are so commonly found in the kernel, and therefore prefer this
split-up. On the other hand, C lacks namespaces, which sometimes leads to
some really long and ugly names just to prevent clashes in the future. But
it's your call, I'll just do whatever it takes to get in... ;-)

    kmemcheck: divide and conquer

    This patch splits the kmemcheck.c into a subdirectory of many files. This
    makes it easier to get around the different functions because they're now
    grouped together by file.
