The VEC has a different address (0x7ec13000) on the BCM2711 (used in
e.g. Raspberry Pi 4) compared to BCM283x (e.g. Pi 3 and earlier). This
was erroneously not taken account for.
Definition of the VEC in the devicetrees had to be moved from
bcm283x.dtsi to bcm2711.dtsi and bcm2835-common.dtsi to allow for this
differentiation.

Rebooting xtensa images loaded with the '-kernel' option in qemu does
not work. When executing a reboot command, the qemu session either hangs
or experiences an endless sequence of error messages.
Kernel panic - not syncing: Unrecoverable error in exception handler
Reset code jumps to the CPU restart address, but Linux can not recover
from there because code and data in the kernel init sections have been
discarded and overwritten at this point.
XTFPGA platforms have a means to reset the CPU by writing 0xdead into a
specific FPGA IO address. When used in QEMU the kernel image loaded with
the '-kernel' option gets restored to its original state allowing the
machine to boot successfully.
Use that mechanism to attempt a platform reset. If it does not work,
fall back to the existing mechanism.

Commit e31694e0a7 ("objtool: Don't make .altinstructions writable")
aligned objtool-created and kernel-created .altinstructions section
flags, but there remains a minor discrepency in their use of a section
entry size: objtool sets one while the kernel build does not.
While sh_entsize of sizeof(struct alt_instr) seems intuitive, this small
deviation can cause failures with external tooling (kpatch-build).
Fix this by creating new .altinstructions sections with sh_entsize of 0
and then later updating sec->sh_size as alternatives are added to the
section. An added benefit is avoiding the data descriptor and buffer
created by elf_create_section(), but previously unused by
elf_add_alternative().

In current code, when a PCI error state pci_channel_io_normal is detectd,
it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI
driver will continue the execution of PCI resume callback report_resume by
pci_walk_bridge, and the callback will go into amdgpu_pci_resume
finally, where write lock is releasd unconditionally without acquiring
such lock first. In this case, a deadlock will happen when other threads
start to acquire the read lock.
To fix this, add a member in amdgpu_device strucutre to cache
pci_channel_state, and only continue the execution in amdgpu_pci_resume
when it's pci_channel_io_frozen.

SYNC_STATE_ONLY device links intentionally allow cycles because cyclic
sync_state() dependencies are valid and necessary.
However a SYNC_STATE_ONLY device link where the consumer and the supplier
are the same device is pointless because the device link would be deleted
as soon as the device probes (because it's also the consumer) and won't
affect when the sync_state() callback is called. It's a waste of CPU cycles
and memory to create this device link. So reject any attempts to create
such a device link.
