dmabuf internals that nvgpu relies upon for storing meta-data for
compressible buffers changed in k6.1. For now, disable compression
on all k6.1+ kernels.
Additionally, fix numerous compilation issues due to the bit rotted
compression config. All normal Tegra products support compression
and thus have this config enabled. Over the last several years
compression dependent code crept in that wasn't protected under the
compression config.

There are three issues with shadow domain submission:
1. runlist mem is not being swapped with mem_hw for shadow domain when
there is non-shadow domain being bound to tsg which does not allow runlist
to have all the tsgs. To fix this nvgpu_runlist_swap_mem() is being called
for shadow domain as well.
2. tsg num_active_channels is being set as part of non-shadow domain which
does happen after shadow domain. Due to this, runlist tsg length is not
being set as part of runlist reconstruct and leaving tsg length 0 for last
tsg. To fix this, tsg num_active_channels always get set for shadow domain
as it gets configured first.
3. NV_BUILD_CONFIGURATION_VARIANT_IS_EMBEDDED is not solving the purpose
to differentiate l4t and embedded_linux builds so using
NV_BUILD_SYSTEM_TYPE in place of this to find out the build type.
L4t is using round robin scheduling and this issue coming with manual mode
scheduling so adding the fix only for manual mode scheduling support.

nvpmodel updates the devfreq frequency limits as per power requirements

to maximum supported frequency which may lead to leaking power and
over heating.
Add support to get the devfreq limits by registering PM_QOS notifiers.
Note that with this patch we enable CONFIG_GK20A_PM_QOS when PM_DEVFREQ
is enabled. So it will be enabled for all supported kernels (4.9, 4.14
kernels continue to support this. For 5.10+ kernels notifiers added in
this patch will be used. Thermal framework related notifiers for kernels
after 4.14 will not be registered as those use downstream interfaces
that are not available.)
We maintain devfreq min/max limits in the scale profile and update those
in the notifier calls. We use these limits to clamp the frequency in the
clock arbiter.

The REMAP ioctl accepts a list of operations (each a map or unmap) that
modify the VM area pages tracked by the virtual mmemory pool.
Inclusion of REMAP support in the nvgpu build is controlled by the new
CONFIG_NVGPU_REMAP flag. This flag is enabled by default for linux builds.
A new NVGPU_GPU_FLAGS_SUPPORT_REMAP characteristics flag is added for use

When a VM allocation tagged with NVGPU_VM_AREA_ALLOC_SPARSE is made the
base virtual memory pool resources are allocated. Per-page resources are
later allocated when the NVGPU_AS_IOCTL_REMAP ioctl is issued. All REMAP
resources are released when the corresponding VM area is freed.

Kstable branch is getting rid of all downstream patches. This also
removes support for NVGPU build as kernel overlays will no longer be
supported.
In order to move towards a uniform out of tree build
system, nvgpu must manage the CONFIGS present in Kconfig itself and stop
relying on Kconfigs.
A new file Makefile.linux.configs is created to house these configs temporarily.
This file is included as part of the linux Makefile. Eventually the plan is to
move towards using Makefile.shared.configs.
This takes us one more step closer to having out of tree module building
for NVGPU internal builds.
With this change, kstable can still go ahead with building extmod builds for NVGPU.
This also allows downstream builds to continue as in-tree builds as long as the
overlays are set for the downstream kernels.
