clang on RISC-V appears to be unaffected by the bug causing excessive
stack usage in calculate_bandwidth(). clang 16 with -fstack-usage
reports a 304 byte stack frame size with CONFIG_ARCH_RV32I, and 512
bytes with CONFIG_ARCH_RV64I.

LoongArch now provides kernel_fpu_begin() and kernel_fpu_end() that are
used like the x86 counterparts in commit 2b3bd32ea3a22ea2d ("LoongArch:
Provide kernel fpu functions"), so we can enable DC_FP on LoongArch for
supporting more DCN devices.

<title>powerpc/64: Always build with 128-bit long double</title>

<id>urn:sha1:78f0929884d4811c225fd2c57ecc602c84c07392</id>
<content type='text'>
The amdgpu driver builds some of its code with hard-float enabled,
whereas the rest of the kernel is built with soft-float.

When building with 64-bit long double, if soft-float and hard-float
objects are linked together, the build fails due to incompatible ABI
tags.

In the past there have been build errors in the amdgpu driver caused by
this, some of those were due to bad intermingling of soft &amp; hard-float
code, but those issues have now all been fixed since commit 58ddbecb14c7
("drm/amd/display: move remaining FPU code to dml folder").

However it's still possible for soft &amp; hard-float objects to end up
linked together, if the amdgpu driver is built-in to the kernel along
with the test_emulate_step.c code, which uses soft-float. That happens
in an allyesconfig build.

Currently those build errors are avoided because the amdgpu driver is
gated on 128-bit long double being enabled. But that's not a detail the
amdgpu driver should need to be aware of, and if another driver starts
using hard-float the same problem would occur.

All versions of the 64-bit ABI specify that long-double is 128-bits.
However some compilers, notably the kernel.org ones, are built to use
64-bit long double by default.

Apart from this issue of soft vs hard-float, the kernel doesn't care
what size long double is. In particular the kernel using 128-bit long
double doesn't impact userspace's ability to use 64-bit long double, as
musl does.

So always build the 64-bit kernel with 128-bit long double. That should
avoid any build errors due to the incompatible ABI tags. Excluding the
code that uses soft/hard-float, the vmlinux is identical with/without
the flag.

It does mean any code which is incorrectly intermingling soft &amp;
hard-float code will build without error, so those bugs will need to be
caught by testing rather than at build time.

For more background see:
  - commit d11219ad53dc ("amdgpu: disable powerpc support for the newer display engine")
  - commit c653c591789b ("drm/amdgpu: Re-enable DCN for 64-bit powerpc")

[Why &amp; How]
The only reason we have the DCN config is for
floating point support. Rename it to make that
clear and (hopefully) avoid misuse of the config
in the future.

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for
