Single page and coherent memory blocks can use different DMA masks
when the macb accesses physical memory directly. The kernel is clever
enough to allocate pages that fit into the requested address width.
When using the ARM SMMU, the DMA mask must be the same for single
pages and big coherent memory blocks. Otherwise the translation
tables turn into one big mess.

Don't clip the damage rectangle against the viewport. This only
works if the viewport is located at the beginning of the video
memory and the video memory doesn't extend the screen (i.e., if
there's no overallocation).
Fbdev emulation transfers data from write operations into a
possible shadow buffer, then into a GEM buffer object, and finally
via graphics driver onto the screen.
If callers write outside the currently visible area, clipping the
damage rectangle against the viewport will loose these updates in
the shadow buffer and the fbdev's buffer object will contain stale
data. Panning the viewport to the stale area of the buffer will
display obsolete data.
Instead, mark all written areas as damaged, so that the damage
handler updates the buffer object from the shadow buffer for all
such areas. The graphics driver's later has the option of clipping
the damaged area against the viewport when updating the screen
from the buffer object.

The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.
This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.
tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16. To
avert any risk of bit overflow, we add an extra sanity check for this in
that function. We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer. This potential problem was identified by Eric Dumazet.

In commit da0363f7bf ("ASoC: qcom: Fix for DMA interrupt clear reg
overwriting") we changed regmap_write() to regmap_update_bits() so that
we can avoid overwriting bits that we didn't intend to modify.
Unfortunately this change breaks the case where a register is writable
but not readable, which is exactly how the HDMI irq clear register is
designed (grep around LPASS_HDMITX_APP_IRQCLEAR_REG to see how it's
write only). That's because regmap_update_bits() tries to read the
register from the hardware and if it isn't readable it looks in the
regmap cache to see what was written there last time to compare against
what we want to write there. Eventually, we're unable to modify this
register at all because the bits that we're trying to set are already
set in the cache.
This is doubly bad for the irq clear register because you have to write
the bit to clear an interrupt. Given the irq is level triggered, we see
an interrupt storm upon plugging in an HDMI cable and starting audio
playback. The irq storm is so great that performance degrades
significantly, leading to CPU soft lockups.
Fix it by using regmap_write_bits() so that we really do write the bits
in the clear register that we want to. This brings the number of irqs
handled by lpass_dma_interrupt_handler() down from ~150k/sec to ~10/sec.

It seems that calling invalidate_kernel_vmap_range() is more correct
to be called before dma_sync_*(), judging from the other thread:
https://lore.kernel.org/all/20220111085958.GA22795@lst.de/
Although this won't matter much in practice, let's fix the call order
for consistency.

dma_need_sync() checks each DMA address. Fix the incorrect usages
for non-contiguous and non-coherent page allocations.
Fortunately, there are no actual call sites that need manual syncs
yet.

The literals "big-endian" and "little-endian" may be potentially
occurred in other places. Dropping space allows linker to
merge them by using only a single copy.

The %p4cc specifier in some cases might get an unaligned pointer.
Due to this we need to make copy to local variable once to avoid
potential crashes on some architectures due to improper access.

For some reason we are selecting PRIO_HAS_PAGES when we don't have
mm.pages, and vice versa.
