when allocating userptr buffer in system ram with size bigger
than or equal 512G, TTM has limit and returns error, to split one
big buffer into multiple small buffers in vm_object will solve
this issue.

If unmap from GPU return failed, for example, unmap user queue buffer
while queue is active, we should not free obj->mapped_node_id_array,
otherwise, the following unmap user queue buffer after queue is
destroyed still return failed.

Since GFX950 can support page table fragment up to 18 without
performance loss. So set GFX950 default svm.alignment_order to 18.

This reverts commit 80da7d5ee4.
Reason for revert: This will put back the change ID - Id1154f08f6ba21c633905fd46b06053994d6f3cc to ROCR repo, which will prevent memory allocations from being automatically granted the 'executable' flag, addressing previously - incorrect and unsafe behavior in ROCm driver.

This reverts commit 75143555fa.
Reason for revert:
This is currently breaking some tools. Will put it back as soon as tools update their code.

Fixed multiple issues related to memory management, atomicity,
and error handling across various functions: handle null checks,
use-after-free, unchecked returns, and memory leaks.

Currently registering graphics memory without specifying a target
node will return a memory handle that's not a virtual address.
As a result, ROCr is forced to register with a target node for
IPC usage.
Mapping memory without specifying a target node afterwards will
result in mapping to the target node that was imported because the
previous import call flags this node targeting action to future mapping.
For ROCr IPC usage, ROCr wants to map to all GPU nodes if the target node
is not specified.
Allow the caller to register graphics handles that returns a virtual
address without having to specify the target node so that the caller
can make a subsequent map call to all GPUs.

We had skipped doing it for PAGE_SIZE, but it should be left as the
regular PAGE_SHIFT name, especially for users who are using different
headers. We want PAGE_SHIFT and PAGE_SIZE to be consistent with one
another, so set them both explicitly to the same value if either
of them is undefined

To support fully-static library ROCm builds, ensure that all global
symbols are prefixed with something meaningful to avoid collisions with
other libraries
A script was made using" objdump -C -t" to get a list of symbols,
then checking if the global symbols have a meaningful prefix (for thunk:
hsakmt or kmt in various cases)
