Some CAN controllers don't implement a FIFO in hardware, but fill their
mailboxes in a particular order (from lowest to highest or highest to lowest).
This makes problems to read the frames in the correct order from the hardware,
as new frames might be filled into just read (low) mailboxes. This gets worse,
when following new frames are received into not read (higher) mailboxes.
On the bright side some these CAN controllers put a timestamp on each received
CAN frame. This patch adds support to offload CAN frames in interrupt context,
order them by timestamp and then transmitted in a NAPI context.

Some CAN controllers have a usable FIFO already but can still benefit
from off-loading the CAN controller FIFO. The CAN frames of the FIFO are
read and put into a skb queue during interrupt and then transmitted in a
NAPI context.

snd_seq_pool_done() syncs with closing of all opened threads, but it
aborts the wait loop with a timeout, and proceeds to the release
resource even if not all threads have been closed. The timeout was 5
seconds, and if you run a crazy stuff, it can exceed easily, and may
result in the access of the invalid memory address -- this is what
syzkaller detected in a bug report.
As a fix, let the code graduate from naiveness, simply remove the loop
timeout.

The mediatek IOMMU driver enables some drivers that it does not directly
rely on, and that causes a warning for build testing:

Back when this was first written, dma_supported() was somewhat of a
murky mess, with subtly different interpretations being relied upon in
various places. The "does device X support DMA to address range Y?"
uses assuming Y to be physical addresses, which motivated the current
iommu_dma_supported() implementation and are alluded to in the comment
therein, have since been cleaned up, leaving only the far less ambiguous
"can device X drive address bits Y" usage internal to DMA API mask
setting. As such, there is no reason to keep a slightly misleading
callback which does nothing but duplicate the current default behaviour;
we already constrain IOVA allocations to the iommu_domain aperture where
necessary, so let's leave DMA mask business to architecture-specific
code where it belongs.

Currently, the IPMMU/VMSA driver supports 32-bit I/O Virtual Addresses
only, and thus sets io_pgtable_cfg.ias = 32. However, it doesn't force
a 32-bit IOVA space through the IOMMU Domain Geometry.
Hence if a device (e.g. SYS-DMAC) rightfully configures a 40-bit DMA
mask, it will still be handed out a 40-bit IOVA, outside the 32-bit IOVA
space, leading to out-of-bounds accesses of the PGD when mapping the
IOVA.
Force a 32-bit IOMMU Domain Geometry to fix this.

We had all these corrected in commit 0c8c6ba00cbf ("pinctrl: sunxi:
make bool drivers explicitly non-modular") but this new one recently
crept in.
The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/sunxi/Kconfig:config PINCTRL_SUN5I
drivers/pinctrl/sunxi/Kconfig: def_bool MACH_SUN5I
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

The rework of the suspend/resume handling uses the wrong #ifdef check, leading
