Since commit 89958b7cd9 ("drm/bridge: panel: Infer connector type from
panel by default"), drm_panel_bridge_add() and their variants can return
NULL and an error pointer. This is fine but none of the actual users of
the API are checking for the NULL value. Instead of change all the
users, seems reasonable to return an error pointer instead. So change
the returned value for those functions when the connector type is unknown.

When AMD memory encryption is enabled, some devices may use more than
256KB/sec from the atomic pools. It would be more appropriate to scale
the default size based on memory capacity unless the coherent_pool
option is used on the kernel command line.
This provides a slight optimization on initial expansion and is deemed
appropriate due to the increased reliance on the atomic pools. Note that
the default size of 128KB per pool will normally be larger than the
single coherent pool implementation since there are now up to three
coherent pools (DMA, DMA32, and kernel).
Note that even prior to this patch, coherent_pool= for sizes larger than
1 << (PAGE_SHIFT + MAX_ORDER-1) can fail. With new dynamic expansion
support, this would be trivially extensible to allow even larger initial
sizes.

When a device requires unencrypted memory and the context does not allow

This avoids the remap when CONFIG_DMA_DIRECT_REMAP is not enabled and the

CONFIG_AMD_MEM_ENCRYPT in a subsequent patch.
Keep all memory in these pools unencrypted. When set_memory_decrypted()
fails, this prohibits the memory from being added. If adding memory to
the genpool fails, and set_memory_encrypted() subsequently fails, there
is no alternative other than leaking the memory.

When an atomic pool becomes fully depleted because it is now relied upon
for all non-blocking allocations through the DMA API, allow background
expansion of each pool by a kworker.
When an atomic pool has less than the default size of memory left, kick
off a kworker to dynamically expand the pool in the background. The pool
is doubled in size, up to MAX_ORDER-1. If memory cannot be allocated at
the requested order, smaller allocation(s) are attempted.
This allows the default size to be kept quite low when one or more of the
atomic pools is not used.
Allocations for lowmem should also use GFP_KERNEL for the benefits of
reclaim, so use GFP_KERNEL | GFP_DMA and GFP_KERNEL | GFP_DMA32 for
lowmem allocations.
This also allows __dma_atomic_pool_init() to return a pointer to the pool
to make initialization cleaner.
Also switch over some node ids to the more appropriate NUMA_NO_NODE.

The following execution path is possible:
fsnotify()
[ realign the stack and store previous SP in R10 ]
<IRQ>
[ only IRET regs saved ]
common_interrupt()
interrupt_entry()
<NMI>
[ full pt_regs saved ]
...
[ unwind stack ]
When the unwinder goes through the NMI and the IRQ on the stack, and
then sees fsnotify(), it doesn't have access to the value of R10,
because it only has the five IRET registers. So the unwind stops
prematurely.
However, because the interrupt_entry() code is careful not to clobber
R10 before saving the full regs, the unwinder should be able to read R10
from the previously saved full pt_regs associated with the NMI.
Handle this case properly. When encountering an IRET regs frame
immediately after a full pt_regs frame, use the pt_regs as a backup
which can be used to get the C register values.
Also, note that a call frame resets the 'prev_regs' value, because a
function is free to clobber the registers. For this fix to work, the
IRET and full regs frames must be adjacent, with no FUNC frames in
between. So replace the FUNC hint in interrupt_entry() with an
IRET_REGS hint.

When unwinding an inactive task, the ORC unwinder skips the first frame
by default. If both the 'regs' and 'first_frame' parameters of
unwind_start() are NULL, 'state->sp' and 'first_frame' are later
initialized to the same value for an inactive task. Given there is a
"less than or equal to" comparison used at the end of __unwind_start()
for skipping stack frames, the first frame is skipped.
Drop the equal part of the comparison and make the behavior equivalent
to the frame pointer unwinder.

UNWIND_HINT_FUNC has some limitations: specifically, it doesn't reset

the unwinder could continue to find the registers, but when when it's
this close to kernel exit, unwind hints aren't really needed anymore and
it's fine to just use an empty hint which tells the unwinder to stop.

The PUSH_AND_CLEAR_REGS macro zeroes each register immediately after
pushing it. If an NMI or exception hits after a register is cleared,
but before the UNWIND_HINT_REGS annotation, the ORC unwinder will
wrongly think the previous value of the register was zero. This can
confuse the unwinding process and cause it to exit early.
Because ORC is simpler than DWARF, there are a limited number of unwind
annotation states, so it's not possible to add an individual unwind hint
after each push/clear combination. Instead, the register clearing
instructions need to be consolidated and moved to after the
UNWIND_HINT_REGS annotation.
