8061cf233b misc: mods: fix offset for large allocations 
Fix MODS_VIRTUAL_TO_PHYSICAL for allocations exceeding 4GB

It's unlikely for us to support such large allocations,
but if we ever did, integer overflow would truncate the
allocation offset, resulting in the incorrect PA being
returned.

This change also brings the driver up to date with
the Perforce copy and fixes the version.

2ce330f11a misc: mods: Replace CONFIG_ARCH_TEGRA 
The perforce version of the MODS kernel driver
does not pull in any of the Tegra specific driver
functions. This prevents the perforce driver
from being compiled on any Tegra system or non
Tegra system with CONFIG_ARCH_TEGRA=y.

To allow the perforce driver to be compiled
replace CONFIG_ARCH_TEGRA with MODS_HAS_TEGRA
which is set based on CONFIG_ARCH_TEGRA in git
but left unset in perforce.

62a67b00a8 Fix Smmu IOVA contiguous checking error 
To allocate larger buffer, MODS code is allocating noncontiguous pages
and then calls dma buffer api to do smmu mapping to get a continuous
iova address. This change will fix the error when the scatterlist's
dma  address is 0xffffffffffffffff, skip checking the sg since it's
already merged to the head node.

b5b2def304 misc: mods: improve logging and fix SRIOV 
* Add new cl_* macros for printing client-specific messages.
  This adds client index to messages in code which is called from
  user space.  This makes it easier to diagnose errors when multiple
  clients (processes) open the driver.
* Use kernel print levels appropriate to messages being printed.
* Print process pid when opening the driver.
* Print information about access token being set or released.
* Print information about PCI devices being enabled or disabled.
  PCI device enablement is tied to the driver getting ownership
  of the device.  It also prevents multiple MODS instances from
  owning the same PCI device.
* Print info about device DMA mask, print device DMA mask when DMA
  mapping fails.
* Print more info about SRIOV actions.
* Disable SRIOV when the driver is being closed by the process
  which enables SRIOV.  Leaving SRIOV enabled when disabling PCI
  device is an error and leads to stale functions, unusable on
  subsequent MODS runs.
* Clean up log messages in a few places.

1bc2ff7f74 misc: mods: use kmap when clearing cache

Use kmap_atomic assuming that cache clearing does not sleep.
