Bug 200066741
ACR ucode has mechanism to skip WPR blob copy for second time,
in case WPR size is sent as 0 to acr ucode.
With above there is a saving of around 0.5 ms, but, in
conjunction with acr change to disable LS sig verification,
and scrubbing empty spaces in WPR sections to 0. This change
can reduce railgate exit latency by 4ms
ACR ucodes to be checked in main, as a different CL, and after
getting prod signs for ACR

Make recovery a more straightforward process. When we detect a fault,
trigger MMU fault, and wait for it to trigger, and complete recovery.
Also reset engines before aborting channel to ensure no stray sync

Decrement the ref count on all mapped_buffers belonging to a va_node
when a va_node is freed. This prevents userspace from leaking some
mapped_buffers in some cases.
This does prevent userspace from keeping a buffer around after freeing
a space allocation if the buffer in question is not otherwise ref
counted. Not sure if this is a bad thing for userspace or not.

This speeds up one command buffer heavy benchmark from 82 FPS to 86

Implement several fixes for allowing the GVA address space to grow
to larger than 32GB and increase the address space to 128GB.
o Implement dynamic allocation of PDE backing pages. The memory
to store the PDE entries was hard coded to 1 page. Now the
number of pages necessary is computed dynamically based on the
size of the address space and the size of large pages.
o Fix an arithmetic problem in the gm20b sparse texture code
that caused large address spaces to be truncated when sparse
PDEs/PTEs were being filled in. This caused a kernel panic
when freeing the address space since a lot of the backing
PTE memory was not allocated.
o Change the address space split for large and small pages. Small
pages now occupy the bottom 16GB of the address space. Large
pages are used for the rest of the address space. Now, with a
128GB address space, there are 112GB of large page GVA available.
This patch exists to allow large (16GB) sparse textures to be allocated
without running into lack of memory issues and kernel panics.
