Allow binding of user memory to the AGP GART on systems with HP
Quicksilver AGP bus. This resolves 'bind memory failed' error seen in
dmesg:
[29.365973] [TTM] AGP Bind memory failed.
…
[29.367030] [drm] Forcing AGP to PCI mode
The system doesn't more fail to bind the memory, and hence not falling
back to the PCI mode (if other failures aren't detected).
This is just a simple write down from the following patches:
agp/amd-k7: Allow binding user memory to the AGP GART
agp/hp-agp: Allow binding user memory to the AGP GART

Commit 338e4fab added a missing kfree if the alloc_pci_dev failed

kfree.

alloc_pci_dev allocates some memory, so that memory should be freed before
leaving the function in an error case.
A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
local idexpression x;
expression E;
identifier f1;
iterator I;
@@
x = alloc_pci_dev(...);
<... when != x
when != true (x == NULL || ...)
when != if (...) { <+...x...+> }
when != I (...) { <+...x...+> }
(
x == NULL
|
x == E
|
x->f1
)
...>
* return ...;
// </smpl>

agp: Switch mask_memory() method to take address argument again, not page
broke the parisc AGP driver (again). This patch fixes it.

In commit 07613ba2 ("agp: switch AGP to use page array instead of
unsigned long array") we switched the mask_memory() method to take a
'struct page *' instead of an address. This is painful, because in some
cases it has to be an IOMMU-mapped virtual bus address (in fact,
shouldn't it _always_ be a dma_addr_t returned from pci_map_xxx(), and
we just happen to get lucky most of the time?)

Fix those compiler warnings, which indeed point to a bug:
drivers/char/agp/parisc-agp.c:228: warning: initialization from incompatible pointer type
drivers/char/agp/parisc-agp.c:201: warning: 'parisc_agp_page_mask_memory' defined but not used

This switches AGP to use an array of pages for tracking the
pages allocated to the GART. This should enable GEM on PAE to work
a lot better as we can pass highmem pages to the PAT code and it will
do the right thing with them.

driver core: move klist_children into private structure
Broke our parisc build pretty badly because we touch the klists directly
in three cases (AGP, SBA and GSC). Although GregKH will revert this
patch, there's no reason we should be using the iterators directly, we
can just move to the standard device_for_each_child() API.

The pageattr-array patch that you currently have in tip/master only
enables it for intel-agp, not the others. The attached enables it for
all drivers currently directly using agp_generic_alloc_page() and
agp_generic_destroy_page() (ocal driver is amd-k7-agp).
The new agp_generic_alloc_pages() interface uses the also new
pageattr array interface API. This makes all AGP drivers that
up to now used generic_{alloc,destroy}_page() use it.

It's *wrong* to have
#define log2(n) ffz(~(n))
It should be *reversed*:
#define log2(n) flz(~(n))
or
#define log2(n) fls(n)
or just use
ilog2(n) defined in linux/log2.h.
This patch follows the last solution, recommended by Andrew Morton.
