Preempt fences can sleep waiting for an exec queue suspend operation to
complete. If the system_unbound_wq is used for waiting and the number of
waiters exceeds max_active this will result in other users of the
system_unbound_wq getting starved. Use a device private work queue for
preempt fences to avoid starvation of the system_unbound_wq.
Even though suspend operations can complete out-of-order, all suspend
operations within a VM need to complete before the preempt rebind worker
can start. With that, use a device private ordered wq for preempt fence
waiting.

Rebinding might allocate page-table bos, causing evictions.
To support blocking locking during these evictions,
perform the rebinding in the drm_exec locking loop.
Also Reserve fence slots where actually needed rather than trying to
predict how many fence slots will be needed over a complete
wound-wait transaction.

For each rebind we insert a GuC TLB invalidation and add a
corresponding unordered TLB invalidation fence. This might
add a huge number of TLB invalidation fences to wait for so
rather than doing that, defer the TLB invalidation to the
next ring ops for each affected exec queue. Since the TLB
is invalidated on exec_queue switch, we need to invalidate
once for each affected exec_queue.
v2:
- Simplify if-statements around the tlb_flush_seqno.
(Matthew Brost)
- Add some comments and asserts.

cxl: remove CONFIG_CXL_PMU entry in drivers/cxl/Kconfig
The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.
Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.
There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.
Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

Doing a XE_EXEC with num_batch_buffer == 0 makes signals passed as
argument to be signaled when the last real XE_EXEC is completed.
But to do that it was first pinning all VMAs in drm_gpuvm_exec_lock(),
this patch remove this pinning as it is not required.
This change also help Mesa implementing memory over-commiting recovery
as it needs to unbind not needed VMAs when the whole VM can't fit
in GPU memory but it can only do the unbiding when the last XE_EXEC
is completed.
So with this change Mesa can get the signal it want without getting
out-of-memory errors.

the Intel RAPL driver, new model-specific EPP handling in intel_pstate

Pull KUnit updates from Shuah Khan:
- fix to make kunit_bus_type const
- kunit tool change to Print UML command
- DRM device creation helpers are now using the new kunit device
creation helpers. This change resulted in DRM helpers switching from
using a platform_device, to a dedicated bus and device type used by
kunit. kunit devices don't set DMA mask and this caused regression on
some drm tests as they can't allocate DMA buffers. Fix this problem
by setting DMA masks on the kunit device during initialization.
- KUnit has several macros which accept a log message, which can
contain printf format specifiers. Some of these (the explicit log
macros) already use the __printf() gcc attribute to ensure the format
specifiers are valid, but those which could fail the test, and hence
used __kunit_do_failed_assertion() behind the scenes, did not.
These include: KUNIT_EXPECT_*_MSG(), KUNIT_ASSERT_*_MSG(), and
KUNIT_FAIL()
A nine-patch series adds the __printf() attribute, and fixes all of
the issues uncovered.

This function does not build on 32-bit targets when the compiler
fails to reduce DIV_ROUND_UP() into a shift:
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by xe_migrate.c
>>> drivers/gpu/drm/xe/xe_migrate.o:(pte_update_size) in archive vmlinux.a
There are two instances in this function. Change the first to
use an open-coded shift with the same behavior, and the second
one to a 32-bit calculation, which is sufficient here as the size
is never more than 2^32 pages (16TB).

When the driver is built-in but the tests are in loadable modules,
the helpers don't actually get put into the driver:
ERROR: modpost: "xe_kunit_helper_alloc_xe_device" [drivers/gpu/drm/xe/tests/xe_test.ko] undefined!
Change the Makefile to ensure they are always part of the driver
even when the rest of the kunit tests are in loadable modules.

clang complains about a nonsensical test on builds with a 32-bit phys_addr_t,
which means resizing will always fail:
drivers/gpu/drm/xe/xe_mmio.c:109:23: error: result of comparison of constant 4294967296 with expression of type 'resource_size_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
109 | root_res->start > 0x100000000ull)
| ~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~
Previously, BAR resize was always disallowed on 32-bit kernels, but
this apparently changed recently. Since 32-bit machines can in theory
support PAE/LPAE for large address spaces, this may end up useful,
so change the driver to shut up the warning but still work when
phys_addr_t/resource_size_t is 64 bit wide.

Mesa has been issuing a single bind operation per ioctl since xe.ko
changed to GPUVA due xe.ko bug #746. If I change Mesa to try again to
issue every single bind operation it can in the same ioctl, it hits
the MAX_BINDS assertion when running Vulkan conformance tests.
Test dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8
issues 960 bind operations in a single ioctl, it's the most I could
find in the conformance suite.
I don't see a reason to keep the MAX_BINDS restriction: it doesn't
seem to be preventing any specific issue. If the number is too big for
the memory allocations, then those will fail. Nothing related to
num_binds seems to be using the stack. Let's just get rid of it.

Those cases missed in previous uAPI cleanups were mostly accidentally
brought in from i915 or created to exercise the possibilities of gpuvm
but they are not used by userspace yet, so let's remove them. They can
still be brought back later if needed.
v2:
- Fix XE_VM_FLAG_FAULT_MODE support in xe_lrc.c (Brian Welty)
- Leave DRM_XE_VM_BIND_OP_UNMAP_ALL (José Roberto de Souza)
- Ensure invalid flag values are rejected (Rodrigo Vivi)

KUNIT_FAIL() is used to fail the xe_migrate test when an error occurs.
However, there's a mismatch in the format specifier: '%li' is used to
log 'err', which is an 'int'.
Use '%i' instead of '%li', and for the case where we're printing an
error pointer, just use '%pe', instead of extracting the error code
manually with PTR_ERR(). (This also results in a nicer output when the
error code is known.)
