drm/amdkfd: Relocate TBA/TMA to opposite side of VM hole
The TBA and TMA, along with an unused IB allocation, reside at low
addresses in the VM address space. A stray VM fault which hits these
pages must be serviced by making their page table entries invalid.
The scheduler depends upon these pages being resident and fails,
preventing a debugger from inspecting the failure state.
By relocating these pages above 47 bits in the VM address space they
can only be reached when bits [63:48] are set to 1. This makes it much
less likely for a misbehaving program to generate accesses to them.
The current placement at VA (PAGE_SIZE*2) is readily hit by a NULL
access with a small offset.
v2:
- Move it to the reserved space to avoid concflicts with Mesa
- Add macros to make reserved space management easier
v3:
- Move VM max PFN calculation into AMDGPU_VA_RESERVED macros

drm/amdgpu: Enable seq64 manager and fix bugs
- Enable the seq64 mapping sequence.
- Fix wflinfo va conflict and other bugs.

drm/amdgpu: Enable seq64 manager and fix bugs
- Enable the seq64 mapping sequence.
- Fix wflinfo va conflict and other bugs.
v1:
- The seq64 area needs to be included in the AMDGPU_VA_RESERVED_SIZE
otherwise the areas will conflict with user space allocations (Alex)
- It needs to be mapped read only in the user VM (Alex)
v2:
- Instead of just one define for TOP/BOTTOM
reserved space separate them into two (Christian)
- Fix the CPU and VA calculations and while at it
also cleanup error handling and kerneldoc (Christian)

drm/amdgpu: Implement a new 64bit sequence memory driver
Developed a new driver which allocates a 64bit memory on
each request in sequence order. At the moment, user queue
fence memory is the main consumer of this seq64 driver.
v2: Worked on review comments from Christian for the following
modifications
- Move driver name from "semaphore" to "seq64"
- Remove unnecessary PT/PD mapping
- Move enable_mes check into init/fini functions.
v3: Worked on review comments from Christian
- drop enable_mes check
- use DECLARE_BITMAP for bit array
- added kerneldoc for seq64
v4: Worked on review comments from Christian
- Rename amdgpu_seq64_get name with amdgpu_seq64_alloc
v5: Worked on review comments from Christian
- Fix seq64 lockdep warning
- move fpriv->seq64_va check into amdgpu_seq64_unmap()
- make the function amdgpu_seq64_unmap() return as void.
- reserve the buffers as not interruptible.
v6: port to drm_exec (Alex)
v7: disable for now (Arun)
