user cases:
1. KFD wraps amdgpu_bo_create, they have no fallback case which is different
with amdgpu_gem_object_create.
since upstream branch has no amdgpu_amdkfd_gpuvm.c, which need KFD
guys add this flag to __alloc_memory_of_gpu:
+ flags |= AMDGPU_GEM_CREATE_NO_FALLBACK;
2. UMD can specify this flag for their allocation as well if they like.

Use the new callback to determine whether to use full
asic reset or per IP soft reset. Enables reset to
actually proceed on asics which don't support soft

amdgpu driver checks vgacon_text_force() after some initializations
but without cleaning up. This will result in leaks.
Move the check of vgacon_text_force() to the beginning of
amdgpu_init() for fixing it and also for optimization.

On large-BAR systems the VM page tables for compute are accessed by
the CPU. Always allow CPU access to the page directory so that it can
be used later by the CPU when a VM is converted to a compute VM.

Under some heavy computing environment(e.g. dgemm test), it
takes the asic over 10+ seconds to finish the dispatched job
which will trigger the timeout.
It's quite confusing although it does not seem to bring any
real problems. As a quick workround, we choose to not enfoce
the timeout setting on compute queues.
