d099fc8f54 drm/ttm: new TT backend allocation pool v3 
This replaces the spaghetti code in the two existing page pools.

First of all depending on the allocation size it is between 3 (1GiB) and
5 (1MiB) times faster than the old implementation.

It makes better use of buddy pages to allow for larger physical contiguous
allocations which should result in better TLB utilization at least for
amdgpu.

Instead of a completely braindead approach of filling the pool with one
CPU while another one is trying to shrink it we only give back freed
pages.

This also results in much less locking contention and a trylock free MM
shrinker callback, so we can guarantee that pages are given back to the
system when needed.

Downside of this is that it takes longer for many small allocations until
the pool is filled up. We could address this, but I couldn't find an use
case where this actually matters. We also don't bother freeing large
chunks of pages any more since the CPU overhead in that path isn't really
that important.

The sysfs files are replaced with a single module parameter, allowing
users to override how many pages should be globally pooled in TTM. This
unfortunately breaks the UAPI slightly, but as far as we know nobody ever
depended on this.

Zeroing memory coming from the pool was handled inconsistently. The
alloc_pages() based pool was zeroing it, the dma_alloc_attr() based one
wasn't. For now the new implementation isn't zeroing pages from the pool
either and only sets the __GFP_ZERO flag when necessary.

The implementation has only 768 lines of code compared to the over 2600
of the old one, and also allows for saving quite a bunch of code in the
drivers since we don't need specialized handling there any more based on
kernel config.

Additional to all of that there was a neat bug with IOMMU, coherent DMA
mappings and huge pages which is now fixed in the new code as well.

v2: make ttm_pool_apply_caching static as reported by the kernel bot, add
    some more checks
v3: fix some more checkpatch.pl warnings

db9c1734ad drm/ttm: stop dangerous caching attribute change 
When we swapout/in a BO we try to change the caching
attributes of the pages before/after doing the copy.

On x86 this is done by calling set_pages_uc(),
set_memory_wc() or set_pages_wb() for not highmem pages
to update the linear mapping of the page.

On all other platforms we do exactly nothing.

Now on x86 this is unnecessary because copy_highpage() will
either create a temporary mapping of the page which is wb
anyway and destroyed immediately again or use the linear
mapping with the correct caching attributes.

So stop this nonsense and just keep the caching as it is and
return an error when a driver tries to change the caching of
an already populated TT object.

This is much more defensive since changing caching
attributes is platform and driver specific and usually
doesn't work after the page was initially allocated.
