[RFC PATCH 0/4] -mm-only hugetlb updates

[Nishanth Aravamudan <nacc@us.ibm.com>]

As Nick requested, I've moved /sys/kernel/hugepages to
/sys/kernel/mm/hugepages. I put the creation of the /sys/kernel/mm
kobject in mm_init.c and that required removing the conditional
compilation of that file. This also necessitated a bit of Documentation
updates (and the addition of the /sys/kernel/mm ABI file). Finally, I
realized that kobject usage doesn't require CONFIG_SYSFS, so I was able
to remove one ifdef from hugetlb.c.

Andrew, I believe these patches, if acceptable, should be folded in
place, if possible, in the hugetlb series (that is, the sysfs location
should only ever have appeared to be /sys/kernel/mm/hugepages). The ease
with which that can occur I guess depends on where Mel's
DEBUG_MEMORY_INIT patches are in the series.

1/4: mm: remove mm_init compilation dependency on CONFIG_DEBUG_MEMORY_INIT
2/4: mm: create /sys/kernel/mm
3/4: hugetlb: hang off of /sys/kernel/mm rather than /sys/kernel
4/4: hugetlb: remove CONFIG_SYSFS dependency

Thanks,
Nish
