- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
the entire panic handling code in our fbdev emulation. We might
restore kms panic output, but not through the bazillion of legacy
code layers called fbdev/fbcon, there's just no way to make that
work safely.
- With the module check change FBINFO_DEFAULT is always 0, so can be
removed too.
That removes another change to cargo-cult stuff in kms drivers, yay!

A couple of Kconfig changes which make it much easier to switch to the
new CONFIG_ORC_UNWINDER:
1) Remove x86 dependencies on CONFIG_FRAME_POINTER for lockdep,
latencytop, and fault injection. x86 has a 'guess' unwinder which
just scans the stack for kernel text addresses. It's not 100%
accurate but in many cases it's good enough. This allows those users
who don't want the text overhead of the frame pointer or ORC
unwinders to still use these features. More importantly, this also
makes it much more straightforward to disable frame pointers.
2) Make CONFIG_ORC_UNWINDER depend on !CONFIG_FRAME_POINTER. While it
would be possible to have both enabled, it doesn't really make sense
to do so. So enforce a sane configuration to prevent the user from
making a dumb mistake.
With these changes, when you disable CONFIG_FRAME_POINTER, "make
oldconfig" will ask if you want to enable CONFIG_ORC_UNWINDER.

Add the new ORC unwinder which is enabled by CONFIG_ORC_UNWINDER=y.
It plugs into the existing x86 unwinder framework.
It relies on objtool to generate the needed .orc_unwind and
.orc_unwind_ip sections.
For more details on why ORC is used instead of DWARF, see
Documentation/x86/orc-unwinder.txt - but the short version is
that it's a simplified, fundamentally more robust debugninfo
data structure, which also allows up to two orders of magnitude
faster lookups than the DWARF unwinder - which matters to
profiling workloads like perf.
Thanks to Andy Lutomirski for the performance improvement ideas:
splitting the ORC unwind table into two parallel arrays and creating a
fast lookup table to search a subset of the unwind table.

The i40e driver attempts to display the UDP tunnel name by doing a check
against the type, where for non-zero types we use "vxlan" and for zero
type we use "geneve". This is not future proof, because if new tunnel
types get added, we'll incorrectly label them. It also depends on the
value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle.
Instead, replace this with a function that can return a constant string
depending on the type. For now we'll use "unknown" for types we don't
know about, and we can expand this in the future if new types get added.

During certain events such as a CORER, multiple devices will run a work
task to handle some cleanup. This can cause issues due to
a single-threaded workqueue which can mean that a device doesn't cleanup
in time. Prevent this by removing the single-threaded restriction on the
module workqueue. This avoids the need to add more complex yielding
logic in our service task routine. This is also similar to what other

- This is part of a 'VPFE_CMD_S_CCDC_RAW_PARAMS' ioctl command that is

- The code to allocate the table never gets called after we copy_from_user

- We then go on to use an address provided by user space as both the

In venus_boot(), we pass a pointer to a phys_addr_t
into dmam_alloc_coherent, which the compiler warns about:
platform/qcom/venus/firmware.c: In function 'venus_boot':
platform/qcom/venus/firmware.c:63:49: error: passing argument 3 of 'dmam_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
To avoid the error refactor venus_boot function by discard
dma_alloc_coherent invocation because we don't want to map the
memory for the device. Something more, the usage of
DMA mapping API is actually wrong and the current
implementation relies on several bugs in DMA mapping code.
When these bugs are fixed that will break firmware loading,
so fix this now to avoid future troubles.
The meaning of venus_boot is to copy the content of the
firmware buffer into reserved (and memblock removed)
block of memory and pass that physical address to the
trusted zone for authentication and mapping through iommu
form the secure world. After iommu mapping is done the iova
is passed as ane entry point to the remote processor.
After this change memory-region property is parsed manually
and the physical address is memremap to CPU, call mdt_load to
load firmware segments into proper places and unmap
reserved memory.

The problem is that in the error case, we've incremented the data ptr
but not decremented rem_bytes, and keep reading (presumably garbage)
until eventually we go beyond the end of the buffer.
Instead, on first error, we should probably just bail out. Other
option is to increment read_bytes by sizeof(u32) before the switch,
rather than only accounting for the ptype header in the non-error
case. Note that in this case it is HFI_ERR_SYS_INVALID_PARAMETER,
ie. an unrecognized/unsupported parameter, so interpreting the next
word as a property type would be bogus. The other error cases are
due to truncated buffer, so there isn't likely to be anything valid
to interpret in the remainder of the buffer. So just bailing seems
like a reasonable solution.

The problem as usual are incorrect #ifdefs, so the easiest fix
is to do away with the #ifdef completely and mark the suspend/resume
handlers as __maybe_unused, which they are.

The persistent_config option is used to make the CEC settings persistent by using
the eeprom inside the device to store this information. This was on by default, which
caused confusion since this device now behaves differently from other CEC devices
which all come up unconfigured.
Another reason for doing this now is that I hope a more standard way of selecting
persistent configuration will be created in the future. And for that to work all
CEC drivers should behave the same and come up unconfigured by default.
None of the open source CEC applications are using this CEC framework at the moment
so change this behavior before it is too late.

I noticed an array underflow in ov5693_enum_frame_size(). The code
looks like this:
int index = fse->index;
if (index >= N_RES)
retur -EINVAL;
fse->index is a u32 that comes from the user. We want negative values
to be counted as -EINVAL but they aren't. There are several ways to fix
this but I feel like the best fix for future proofing is to change the
type of N_RES from int to unsigned long to make it the same as if we
were comparing against ARRAY_SIZE().

The vimc platform drivers define a platform device ID table but these
are not set to the .id_table field in the platform driver structure.
So the platform device ID table is only used to fill the aliases in
the module but are not used for matching (works because the platform
subsystem fallbacks to the driver's name if no .id_table is set).
But this also means that the platform device ID table isn't used if
the driver is built-in, which leads to the following build warning:
This causes the following build warnings when the driver is built-in:

When adding a large scatterlist entry that covers more than the L3
superpage size (1GB) but has an alignment such that we must use L2
superpages (2MB) , we give dma_pte_free_level() a range that causes it
to free the L3 pagetable we're about to populate. We fix this by telling
dma_pte_free_pagetable() about the pagetable level we're about to populate
to prevent freeing it.
For example, mapping a scatterlist with entry lengths 854MB and 1194MB
at IOVA 0xffff80000000 would, when processing the 2MB-aligned second
entry, cause pfn_to_dma_pte() to create a L3 directory to hold L2
superpages for the mapping at IOVA 0xffffc0000000. We would previously
call dma_pte_free_pagetable(domain, 0xffffc0000, 0xfffffffff), which
would free the L3 directory pfn_to_dma_pte() just created for IO PFN
0xffffc0000. Telling dma_pte_free_pagetable() to retain the L3
directories while using L2 superpages avoids the erroneous free.

When a PCI device has DMA quirks, we need to ensure that an upstream
IOMMU knows about all possible aliases, since the presence of a DMA
quirk does not preclude the device still also emitting transactions
(e.g. MSIs) on its 'real' RID. Similarly, the rules for bridge aliasing
are relatively complex, and some bridges may only take ownership of
transactions under particular transient circumstances, leading again to
multiple RIDs potentially being seen at the IOMMU for the given device.
Take all this into account in the OF code by translating every RID
produced by the alias walk, not just whichever one comes out last.
Happily, this also makes things tidy enough that we can reduce the
number of both total lines of code, and confusing levels of indirection,
by pulling the "iommus"/"iommu-map" parsing helpers back in-line again.
