Starting with GCC 12.1, the created .gcda format can't be read by gcov
tool. There are 2 significant changes to the .gcda file format that
need to be supported:
a) [gcov: Use system IO buffering]
(23eb66d1d46a34cb28c4acbdf8a1deb80a7c5a05) changed that all sizes in
the format are in bytes and not in words (4B)
b) [gcov: make profile merging smarter]
(72e0c742bd01f8e7e6dcca64042b9ad7e75979de) add a new checksum to the
file header.
Tested with GCC 7.5, 10.4, 12.2 and the current master.

Inside the zs_destroy_pool() function, there can still be NULL size_class
pointers: if when the next size_class is allocated, inside
zs_create_pool() function, kzalloc will return NULL and handling the error
condition, zs_create_pool() will call zs_destroy_pool().

Fuzzing produced an invalid argument to vma_merge() which was caught by
the newly added verification of the number of VMAs being removed on
process exit. Analyzing the failure eventually resulted in finding an
issue with the search of a VMA that started at address 0, which caused an
underflow and thus the loss of many VMAs being tracked in the tree. Fix
the underflow by changing the search of the maple tree to use the start
address directly.

Commit 8795e182b0 ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
uncovered a bug in amdgpu that required a reordering of the driver
init sequence to avoid accessing a special register on the GPU
before it was properly set up leading to an PCI AER error. This
reordering uncovered a different hw programming ordering dependency
in some APUs where the SDMA doorbells need to be programmed before
the GFX doorbells. To fix this, move the SDMA doorbell programming
back into the soc15 common code, but use the actual doorbell range
values directly rather than the values stored in the ring structure
since those will not be initialized at this point.
This is a partial revert, but with the doorbell assignment
fixed so the proper doorbell index is set before it's used.

Commit c347a787e3 (drbd: set ->bi_bdev in drbd_req_new) moved a
bio_set_dev call (which has since been removed) to "earlier", from
drbd_request_prepare to drbd_req_new.
The problem is that this accesses device->ldev->backing_bdev, which is
not NULL-checked at this point. When we don't have an ldev (i.e. when
the DRBD device is diskless), this leads to a null pointer deref.
So, only allocate the private_bio if we actually have a disk. This is
also a small optimization, since we don't clone the bio to only to
immediately free it again in the diskless case.

__le32 and __le64 types aren't portable and are not available on
FreeBSD (which uses the same uAPI).
Instead of attempting to always output little endian, just use native
endianness in the dumps. Tools can detect the endianness in use by
looking at the 'magic' field, but equally we don't expect big-endian to
be used with Mali (there are no known implementations out there).

The two structs internal to struct panfrost_dump_object_header were
named, but sadly that is incompatible with C++, causing an error: "an
anonymous union may only have public non-static data members".
However nothing refers to struct pan_reg_hdr and struct pan_bomap_hdr
and there's no need to export these definitions, so lets drop them. This
fixes the C++ build error with the minimum change in userspace API.

Commit 35a3b82f1b ("drm/connector: Introduce drmm_connector_init")
introduced the function drmm_connector_init() with a parameter for an
optional ddc pointer to the i2c controller used to access the DDC bus.
However, the underlying call to __drm_connector_init() was always
setting it to NULL instead of passing the ddc argument around.
This resulted in unexpected null pointer dereference on platforms
expecting to get a DDC controller.

The xrgb2101010 format conversion test (unlike for other formats) does
an endianness conversion on the results. However, it always converts
TEST_BUF_SIZE 32-bit integers, which results in reading from (and
writing to) more memory than in present in the result buffer. Instead,
use the buffer size, divided by sizeof(u32).
The issue could be reproduced with KASAN:
./tools/testing/kunit/kunit.py run --kunitconfig drivers/gpu/drm/tests \
--kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \
--kconfig_add CONFIG_KASAN_KUNIT_TEST=y \

If the cable is disconnected the PHY seems to toggle between MDI and
MDI-X modes. With the MDI crossover status interrupt active this causes
roughly 10 interrupts per second.
As the crossover status isn't checked by the driver, the interrupt can
be disabled to reduce the interrupt load.

When we compile-in the CCI along with the imx412 driver and run on the RB5
we see that i2c_add_adapter() causes the probe of the imx412 driver to
happen.
This probe tries to perform an i2c xfer() and the xfer() in i2c-qcom-cci.c
fails on pm_runtime_get() because the i2c-qcom-cci.c::probe() function has
not completed to pm_runtime_enable(dev).
Fix this sequence by ensuring pm_runtime_xxx() calls happen prior to adding
the i2c adapter.

Assigning the device's dma_range_map from the iterator variable after

won't work either. Fix this.
