____cacheline_maxaligned_in_smp is currently used to align critical structures
and avoid false sharing.  It uses per-arch L1_CACHE_SHIFT_MAX and people find
L1_CACHE_SHIFT_MAX useless.

However, we have been using ____cacheline_maxaligned_in_smp to align
structures on the internode cacheline size.  As per Andi's suggestion,
following patch kills ____cacheline_maxaligned_in_smp and introduces
INTERNODE_CACHE_SHIFT, which defaults to L1_CACHE_SHIFT for all arches.
Arches needing L3/Internode cacheline alignment can define
INTERNODE_CACHE_SHIFT in the arch asm/cache.h.  Patch replaces
____cacheline_maxaligned_in_smp with ____cacheline_internodealigned_in_smp

With this patch, L1_CACHE_SHIFT_MAX can be killed

The structure ide_driver_t have a .owner field which is a duplicate
of .gendriver.owner field (.gen_driver is a struct device_driver).

This patch removes ide_driver_t's owner field.

A nice feature of sysfs is that it can create the symlink from the
driver to the module that is contained in it.

It requires that the device_driver.owner is set, what is not the
case for many PCI drivers.

This patch allows pci_register_driver to set automatically the
device_driver.owner for any PCI driver.

Credits to Al Viro who suggested the method.

CONFIG_IDE_MAX_HWIFS is a generic thing, no need to have it duplicated
by every arch that uses it.

Devices driven by ide-cs will appear under /sys/devices instead of the
appropriate PCMCIA device. To fix this I had to extend the hw_regs_t
structure with a 'struct device' field, which allows us to set the
parent link for the appropriate hwif.

Patch to allocate the control structures for for ide devices on the node of
the device itself (for NUMA systems).  The patch depends on the Slab API
change patch by Manfred and me (in mm) and the pcidev_to_node patch that I
posted today.

Does some realignment too.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
