In devm_cxl_add_port() the port creation may fail and its associated
pointer does not contain a valid address. During error message
generation this invalid port address is used. Fix that wrong address
access.

Move cxl_await_media_ready() to cxl_pci probe before driver starts issuing
IDENTIFY and retrieving memory device information to ensure that the
device is ready to provide the information. Allow cxl_pci_probe() to succeed
even if media is not ready. Cache the media failure in cxlds and don't ask
the device for any media information.
The rationale for proceeding in the !media_ready case is to allow for
mailbox operations to interrogate and/or remediate the device. After
media is repaired then rebinding the cxl_pci driver is expected to
restart the capacity scan.

The Memory_Info_Valid bit (CXL 3.0 8.1.3.8.2) indicates that the CXL
Range Size High and Size Low registers are valid. The bit must be set
within 1 second of reset deassertion to the device. Check valid bit
before we check the Memory_Active bit when waiting for
cxl_await_media_ready() to ensure that the memory info is valid for
consumption. Also ensures both DVSEC ranges 1 and 2 are ready if DVSEC
Capability indicates they are both supported.

Derick noticed, when testing hot plug, that hot-add behaves nominally
after a removal. However, if the hot-add is done without a prior
removal, CXL.mem accesses fail. It turns out that the original
implementation of the port driver and region programming wrongly assumed
that platform-firmware always enables the host-bridge HDM decoder
capability. Add support turning on switch-level HDM decoders in the case
where platform-firmware has not.
The implementation is careful to only arrange for the enable to be
undone if the current instance of the driver was the one that did the
enable. This is to interoperate with platform-firmware that may expect
CXL.mem to remain active after the driver is shutdown. This comes at the
cost of potentially not shutting down the enable on kexec flows, but it
is mitigated by the fact that the related HDM decoders still need to be
enabled on an individual basis.

UAF happens.

Fix error handling in the arcfb_probe() function. If IO addresses are

The lifetime of object for asynchronous request packet is now maintained
by reference counting, while current implementation of firewire-net
releases the passed object in the handler.
This commit fixes the bug.

gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert.
So in gfx_v9_0_hw_fini, interrupt disablement for cp_ecc_error_irq
should be executed under such condition, otherwise, an amdgpu_irq_put
calltrace will occur.

sdma_v4_0_ip is shared on a few asics, but in sdma_v4_0_hw_fini,
driver unconditionally disables ecc_irq which is only enabled on
those asics enabling sdma ecc. This will introduce a warning in
suspend cycle on those chips with sdma ip v4.0, while without
sdma ecc. So this patch correct this.

[Description]
- Due to bandwidth / arbitration issues at 200Mhz DCFCLK,
we want to enforce minimum 60us of prefetch to avoid
intermittent underflow issues
- Since 60us prefetch is already enforced for UCLK DPM0,
and many DCFCLK's > 200Mhz are mapped to UCLK DPM1, in
theory there should not be any UCLK DPM regressions by
enforcing greater prefetch

of interface to set TX while keeping symclk on. Adding this workaround
to DCN314 will resolve the current issue.
