b9d188d974 video: tegra: nvmap: Deprecate cachelistsync functions 
Remove cachelistsync functions from nvmap as they were only relevant for
older chips.

25bc2a3b96 tegra: nvmap: Clean-up OOT NvMap 
Remove macro-protected dead code. NVMAP_LOADABLE_MODULE enables NvMap as
an OOT module, while NVMAP_UPSTREAM_KERNEL is a config for kstable/OOT
kernel. For Kernel 5.10+ both are always defined, So the related macro
protected code can be safely removed.

069925e74b video: tegra: nvmap: Make ioremap_prot depend on GENERIC_IOREMAP 
The function ioremap_prot() has been exported by the Linux kernel since
v5.9. However, it is only available if GENERIC_IOREMAP is enabled. Since
Linux v6.0, when the ARM64 __ioremap() function was removed, was
GENERIC_IOREMAP enabled for ARM64 by default. Rather than depend on
kernel version for selecting if ioremap_prot is used, use ioremap_prot
if GENERIC_IOREMAP is enabled.

This is a better solution for working with 3rd party Linux kernels that
may backport upstream changes to the kernel and hence are not compatible
with these existing version checks.

edf9d114e1 video: tegra: nvmap: Don't perform repetitive ioremap 
__ioremap function called during cache maint takes more time in case of
multiple processes compared to single process. This is impacting camera
tests when multiple cameras are used. For carveouts, nvmap performs page
by page ioremap and then cache maint on it. Optimize this with following
steps:
- During first cache_maint of the buffer, perform ioremap on entire
buffer and save the kernel V.A.
- Next time, when cache_maint is called on the same buffer, we will
reuse the saved kernel V.A.

6937db210f video: tegra: nvmap: Add CBC carveout support 
- Add CBC carveout suport in nvmap.
- Chunk size for CBC is 2MB, hence each bit from bitmap for CBC carveout
indicate 2MB physically contiguous chunk.
- In case of allocation from CBC, first try to allocate the entire chunk
in physically contiguous manner, if it's not possible then allocate in
chunks of 2MB. All page pointers to these chunks will be stored in
nvmap_handle struct.
- Modify all other operations like vmap, kmap, mmap as per the above
restrictions.

in NvMap, define prototype in nvmap_priv.h, private header.
