PNP: check for conflicts with all resources, not just earlier ones
This patch removes a use of "idx" in pnp_check_port() and similar
functions, in preparation for replacing idx with a pointer to the
resource itself.
I split this out because it changes the behavior slightly: we used
to check for conflicts only with earlier resources, e.g., we checked
resource 2 against resources 0 and 1 but not against 3, 4, etc. Now
we will check against all resources except 2.
Since resources are assigned in ascending order, the old behavior
was probably safe, but I don't like to depend on that ordering.

This adds a pnp_get_resource() that works the same way as
platform_get_resource(). This will enable us to consolidate
many pnp_resource_table references in one place, which will
make it easier to make the table dynamic.

PNP: factor pnp_init_resource_table() and pnp_clean_resource_table()

These are no longer used in the PNP core either, so we can just remove
them completely.
It's possible that there are out-of-tree drivers that use these
interfaces. They should be changed to either (1) use PNP quirks
to work around broken hardware or firmware, or (2) use the sysfs
interfaces to control resource usage from userspace.

PNP: remove pnp_resource_table from internal pnp_clean_resource_table interface
This changes pnp_clean_resource_table() to take a pnp_dev pointer
rather than a pnp_resource_table pointer. This reduces the visibility

Add pnp_init_resources(struct pnp_dev *) to replace
pnp_init_resource_table(), which takes a pointer to the
pnp_resource_table itself. Passing only the pnp_dev * reduces
the possibility for error in the caller and removes the
pnp_resource_table implementation detail from the interface.
Even though pnp_init_resource_table() is exported, I did not
export pnp_init_resources() because it is used only by the PNP

PNP: remove pnp_resource_table from internal get/set interfaces
When we call protocol->get() and protocol->set() methods, we currently

This removes the pnp_resource_table arguments to make it clear that

of zeros in the image mapped in to user processes.
This changes it to put the vdso.so image into normal initdata as we

gone, so the user VMA is one page instead of two. The image that
was already copied around at boot time is now in initdata, so we
