Refactoring 'test' functions into kunit tests, to test utf-8 support in
unicode subsystem.
This allows the utf8 tests to be run alongside the KUnit test suite
using kunit-tool, quickly compiling and running all desired tests as
part of the KUnit test suite, instead of compiling the selftest module
and loading it.
The refactoring kept the original testing logic intact, while adopting a
testing pattern across different kernel modules and leveraging KUnit's
benefits.

This commit introduces KUnit tests for the intlog2 and intlog10
functions, which compute logarithms in base 2 and base 10, respectively.
The tests cover a range of inputs to ensure the correctness of these
functions across common and edge cases.

Commit df542f6693 ("net: stmmac: Switch to zero-copy in
non-XDP RX path") makes DMA write received frame into buffer at offset
of NET_SKB_PAD and sets page pool parameters to sync from offset of
NET_SKB_PAD. But when Header Payload Split is enabled, the header is
written at offset of NET_SKB_PAD, while the payload is written at
offset of zero. Uncorrect offset parameter for the payload breaks dma
coherence [1] since both CPU and DMA touch the page buffer from offset
of zero which is not handled by the page pool sync parameter.
And in case the DMA cannot split the received frame, for example,
a large L2 frame, pp_params.max_len should grow to match the tail
of entire frame.

====================
xsk: the lost bits from Chapter III
Before introducing libeth_xdp, we need to add a couple more generic
helpers. Notably:
* 01: add generic loop unrolling hint helpers;
* 04: add helper to get both xdp_desc's DMA address and metadata
pointer in one go, saving several cycles and hotpath object
code size in drivers (especially when unrolling).
Bonus:
* 02, 03: convert two drivers which were using custom macros to
generic unrolled_count() (trivial, no object code changes).

Currently, when your driver supports XSk Tx metadata and you want to
send an XSk frame, you need to do the following:
* call external xsk_buff_raw_get_dma();
* call inline xsk_buff_get_metadata(), which calls external
xsk_buff_raw_get_data() and then do some inline checks.
This effectively means that the following piece:
addr = pool->unaligned ? xp_unaligned_add_offset_to_addr(addr) : addr;
is done twice per frame, plus you have 2 external calls per frame, plus
this:
meta = pool->addrs + addr - pool->tx_metadata_len;
if (unlikely(!xsk_buff_valid_tx_metadata(meta)))
is always inlined, even if there's no meta or it's invalid.
Add xsk_buff_raw_get_ctx() (xp_raw_get_ctx() to be precise) to do that
in one go. It returns a small structure with 2 fields: DMA address,
filled unconditionally, and metadata pointer, non-NULL only if it's
present and valid. The address correction is performed only once and
you also have only 1 external call per XSk frame, which does all the
calculations and checks outside of your hotpath. You only need to
check `if (ctx.meta)` for the metadata presence.
To not copy any existing code, derive address correction and getting
virtual and DMA address into small helpers. bloat-o-meter reports no
object code changes for the existing functionality.

There are cases when we need to explicitly unroll loops. For example,
cache operations, filling DMA descriptors on very high speeds etc.
Add compiler-specific attribute macros to give the compiler a hint
that we'd like to unroll a loop.
Example usage:
#define UNROLL_BATCH 8
unrolled_count(UNROLL_BATCH)
for (u32 i = 0; i < UNROLL_BATCH; i++)
op(priv, i);
Note that sometimes the compilers won't unroll loops if they think this
would have worse optimization and perf than without unrolling, and that
unroll attributes are available only starting GCC 8. For older compiler
versions, no hints/attributes will be applied.
For better unrolling/parallelization, don't have any variables that
interfere between iterations except for the iterator itself.

Include the standard "[PLANE:%d:s]" stuff in all plane debugs
(or rather all I was able to find), to provide better information
on which plane we're actually talking about.
There are a few spots where we care about the CRTC as well, so
include that where appropriate.

struct intel_display will replace struct drm_i915_private as
the main thing for display code. Convert the skl+ universal plane
code to use it.
Note that we still have two straggles in the form on
HAS_FLAT_CCS() and the pxp stuff.

intel_sprite.c was partially converted to struct intel_display.
Finish the job now that we can deal with the platform checks
as well.
And while at it we also move the 'display' variable declaration
to be the first thing in most functions, consistency. We can
actually do that now since intel_display() accepts the intel_plane
and intel_plane_state types.

Pass intel_display to the display power stuff. These are spread
all over the place so tend to hinder clean conversions of whole
files.
TODO: The gt part/unpark power domain shenanigans need some
kind of more abstract interface...

Make the intel_fb_bo.h interfaces operated purely in base
drm_ types so that each driver (i915 and xe) doesn't have to
know about each other, or the display stuff.

Pass the device argument as drm_device to intel_plane_fb_max_stride()
to decouple i915_gem_dumb_create() vs. the display code a bit.
xe currently doesn't even call this, but it probably should...

Now that intel_scanout_needs_vtd_wa() is no longer used from
the gem code we can convert it to take struct intel_display.
which will help with converting the low level plane code over
as well.
