We've had misc reports of random IOMMU page faults when
this is used.  It's just a rarely used optimization anyway, so
let's just disable it.  It can still be toggled via the
module parameter for testing.

Add a module parameter to control the AGP aperture.  The AGP
aperture is an aperture in the GPU's internal address space
which provides direct non-paged access to the platform address
space.  This access is non-snooped so only uncached memory
can be accessed.

Add a knob so that we can toggle this for debugging.

[WHY]
DENTIST hangs when OTG is off and encoder is on. We were not
disabling the encoder properly when switching from extended mode to
external monitor only.

[HOW]
Disable the encoder using an existing enable/disable fifo helper instead
of enc35_stream_encoder_enable.

[WHY]

2. Only change windows memory to inbox.

[WHY]
On s0i3, IPS mask isn't saved and restored.
It is reset to zero on exit.

If it is cleared unexpectedly, driver will
proceed operations while DCN is in IPS2 and
cause a hang.

[HOW]
Negate the bit logic. Default value of
zero indicates it is still in IPS2. Driver
must poll for the bit to assert.

When ddc_service_construct() is called, it explicitly checks both the
link type and whether there is something on the link which will
dictate whether the pin is marked as hw_supported.

If the pin isn't set or the link is not set (such as from
unloading/reloading amdgpu in an IGT test) then fail the
amdgpu_dm_i2c_xfer() call.

The r535_gsp_cmdq_get() function returns error pointers but this code
checks for NULL.  Also we need to propagate the error pointer back to
the callers in r535_gsp_rpc_get().  Returning NULL will lead to a NULL
pointer dereference.

The if we hit the "continue" statement on the first iteration through
the loop then "handle_mux" needs to be set to NULL so we continue
looping.

Fix the ordering so we won't get following warning:

Merge tag 'parisc-for-6.7-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc architecture fixes from Helge Deller:

 - Include the upper 5 address bits when inserting TLB entries on a
   64-bit kernel.

   On physical machines those are ignored, but in qemu it's nice to have
   them included and to be correct.

 - Stop the 64-bit kernel and show a warning if someone tries to boot on
   a machine with a 32-bit CPU

 - Fix a "no previous prototype" warning in parport-gsc

Pull probes fixes from Masami Hiramatsu:

 - Documentation update: Add a note about argument and return value
   fetching is the best effort because it depends on the type.

 - objpool: Fix to make internal global variables static in
   test_objpool.c.

 - kprobes: Unify kprobes_exceptions_nofify() prototypes. There are the
   same prototypes in asm/kprobes.h for some architectures, but some of
   them are missing the prototype and it causes a warning. So move the
   prototype into linux/kprobes.h.

 - tracing: Fix to check the tracepoint event and return event at
   parsing stage. The tracepoint event doesn't support %return but if
   $retval exists, it will be converted to %return silently. This finds
   that case and rejects it.

 - tracing: Fix the order of the descriptions about the parameters of
   __kprobe_event_gen_cmd_start() to be consistent with the argument
   list of the function.
