Hello.
Just merged the two dicussed patches and fixed an overlooked warning.
v2
- insert a patch refactoring validate_prctl_map
- move find_vma out of the arg_lock critical section

- squash get_cmdline and prctl_set_mm patches (to keep locking
consistency)

The CPU accessible DMA pool is general and not used only for PQ.
Accordingly, this patch rename the "free_cpu_pq_pool" label with

Audio DMA(ADMA) interface is a gateway in the AHUB for facilitating DMA
transfers between memory and all of its clients. Currently the driver
supports Tegra210 based platforms. This series adds support for Tegra186
and Tegra194 based platforms and fixes few functional issues.
Patches in the series
Tegra186 Audio DMA controller has new updates from Tegra210 version.
Thus add new compatibility binding string and the same can be used
by Tegra194 as well.

Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with

debugging is enabled:

Remove the print completely, as it's useless without the address.
Based on commit 0f1bf7e398224
Add Tegra186 specific macro defines and chip_data structure for chip
specific information. New compatibility is added to select relevant
chip details. There is no major change for Tegra194 and hence it can
use the same chip data.

This patch allows to define the max prescaler by compatible.
To set a large range of timeout, the prescaler should be set
dynamically (from the timeout request) to improve the resolution
in order to have a timeout close to the expected value.

The FPU is not a super-Linuxy internal detail, so remove the _GPL
