[Why]
svm ranges can have mixed pages from device or system memory.
A good example is, after a prange has been allocated in VRAM and a
copy-on-write is triggered by a fork. This invalidates some pages
inside the prange. Endding up in mixed pages.
[How]
By classifying each page inside a prange, based on its type. Device or
system memory, during dma mapping call. If page corresponds
to VRAM domain, a flag is set to its dma_addr entry for each GPU.
Then, at the GPU page table mapping. All group of contiguous pages within
the same type are mapped with their proper pte flags.
v2:
Instead of using ttm_res to calculate vram pfns in the svm_range. It is now
done by setting the vram real physical address into drm_addr array.
This makes more flexible VRAM management, plus removes the need to have
a BO reference in the svm_range.
v3:
Remove mapping member from svm_range

The documentation around PrepareMp1ForUnload message says that
anything sent to SMU after this command would be stalled as the
PMFW would not be in a state to take further job requests.
Technically this is right in case of S3 scenario. But, this might
not be the case during s0ix as the PMC driver would be the last
to send the SMU on the OS_HINT. If SMU gets a PrepareMp1ForUnload
message before the OS_HINT, this would stall the entire S0ix process.
Results show that, this message to SMU is not required during S0ix

On the Loongson64 platform used with Radeon GPU, shutdown or reboot failed

radeon_suspend_kms() puts the hw in the suspend state, especially set fb
state as FBINFO_STATE_SUSPENDED:
if (fbcon) {
console_lock();
radeon_fbdev_set_suspend(rdev, 1);
console_unlock();
}
Then avoid to do any more fb operations in the related functions:
if (p->state != FBINFO_STATE_RUNNING)
return;
So call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64 to fix
this issue, it looks like some kind of workaround like powerpc.

The ttm caching flags (ttm_cached, ttm_write_combined etc) are
used to determine a buffer object's mapping attributes in both
CPU page table and GPU page table (when that buffer is also
accessed by GPU). Currently the ttm caching flags are set in
function amdgpu_ttm_io_mem_reserve which is called during
DRM_AMDGPU_GEM_MMAP ioctl. This has a problem since the GPU
mapping of the buffer object (ioctl DRM_AMDGPU_GEM_VA) can
happen earlier than the mmap time, thus the GPU page table
update code can't pick up the right ttm caching flags to
decide the right GPU page table attributes.
This patch moves the ttm caching flags setting to function
amdgpu_vram_mgr_new - this function is called during the
first step of a buffer object create (eg, DRM_AMDGPU_GEM_CREATE)
so the later both CPU and GPU mapping function calls will
pick up this flag for CPU/GPU page table set up.
