When the clients are 32 bits while the kernel is 64 bits,
we need to translate the memory address before accessing.
The previous commit was refreshed by ddk update.

user_atom.atom_number can be indirectly controlled by user-space,
hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/arm/midgard/mali_kbase_jd.c:1397 kbase_jd_submit() warn:
potential spectre issue 'jctx->atoms' [r]
katom = &jctx->atoms[user_atom.atom_number];
Fix this by sanitizing user_atom.atom_number
before 'katom = &jctx->atoms[user_atom.atom_number];'.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Mali sync timeline in Utgard DDK r7p0-00rel1 depends on CONFIG_SYNC.
But, CONFIG_SYNC is no longer supported by kernel v4.19.
This modification is from ARM release：DX910-SW-99002-r9p0-01rel0.tgz

1. use the same mutex to serialize the calls from user application.
2. keep iommu attached state when last video is closed,
because the user application may still access the buffer allocated
by v4l2 driver.

when use hdmi-in chip with isp, it needs to pull out/plug in hdmi cable
when stream is on.
many error logs are reported in interrupt function when pull out/plug in
hdmi cable, then the system will be dead.
so we stop isp when too many error logs are reported.

V4L2_BUF_TYPE_META_OUTPUT was added by commit 72148d1a57
("media: v4l: Add support for V4L2_BUF_TYPE_META_OUTPUT") but the patch
missed adding the type to the macro telling whether a given type is an
output type or not. Do that now. Getting this wrong leads to handling the
buffer as a capture buffer in a lot of places.
