Change device_driver_attach() and driver_attach() to take a const * to
struct device driver as neither of them modify the structure at all.
Also, for some odd reason, drivers/dma/idxd/compat.c had a duplicate
external reference to device_driver_attach(), so remove that to fix up
the build, it should never have had that there in the first place.

When erase/trim/discard completion was converted to mmc_poll_for_busy(),
optional support to poll with the host_ops->card_busy() callback was also
added.
The common sdhci's ->card_busy() turns out not to be working as expected
for the sdhci-brcmstb variant, as it keeps returning busy beyond the card's
busy period. In particular, this leads to the below splat for
mmc_do_erase() when running a discard (BLKSECDISCARD) operation during

PREEMPT_RT has a different locking implementation for ww_mutex. The
base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The
latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex'
for PREEMPT_RT builds.
Using mutex_lock() directly on the base mutex in
ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT.
The locking-selftest has its own defines to deal with this and it is
probably best to defines the needed one within the test program since
their usefulness is limited outside of well known selftests.
Provide ww_mutex_base_lock() which points to the correct function for
PREEMPT_RT and non-PREEMPT_RT builds.

MHI endpoint stack accidentally started allocating memory for objects from
DMA zone since commit 62210a26cd ("bus: mhi: ep: Use slab allocator
where applicable"). But there is no real need to allocate memory from this
naturally limited DMA zone. This also causes the MHI endpoint stack to run
out of memory while doing high bandwidth transfers.
So let's switch over to normal memory.

On platforms where VFs are using memory based interrupts, we
missed invalid access to no longer existing interrupt registers,
as we keep them marked with XE_REG_OPTION_VF. To fix that just
either setup memirq vectors in GuC or enable legacy interrupts.

Commit 05da7d9f71 ("drm/i915/gem: Downgrade stolen lmem setup
warning") adds a debug message where the "lmem_size" and
"dsm_base" variables are printed using the %lli identifier.
However, these variables are defined as resource_size_t, which
are unsigned long for 32-bit machines and unsigned long long for
64-bit machines.
The documentation (core-api/printk-formats.rst) recommends using
the %pa specifier for printing addresses and sizes of resources.
Replace %lli with %pa.
This patch also mutes the following sparse warning when compiling
with:

Shannon Nelson says:
====================
ionic: rework fix for doorbell miss
A latency test in a scaled out setting (many VMs with many queues)
has uncovered an issue with our missed doorbell fix from
commit b69585bfce ("ionic: missed doorbell workaround")
As a refresher, the Elba ASIC has an issue where once in a blue
moon it might miss/drop a queue doorbell notification from
the driver. This can result in Tx timeouts and potential Rx
buffer misses.
The basic problem with the original solution is that
we're delaying things with a timer for every single queue,
periodically using mod_timer() to reset to reset the alarm, and
mod_timer() becomes a more and more expensive thing as there
are more and more VFs and queues each with their own timer.
A ping-pong latency test tends to exacerbate the effect such
that every napi is doing a mod_timer() in every cycle.
An alternative has been worked out to replace this using
periodic workqueue items outside the napi cycle to request a
napi_schedule driven by a single delayed-workqueue per device
rather than a timer for every queue. Also, now that newer
firmware is actually reporting its ASIC type, we can restrict
this to the appropriate chip.
The testing scenario used 128 VFs in UP state, 16 queues per
VF, and latency tests were done using TCP_RR with adaptive
interrupt coalescing enabled, running on 1 VF. We would see
99th percentile latencies of up to 900us range, with some max
fliers as much as 4ms.
With these fixes the 99th percentile latencies are typically well
under 50us with the occasional max under 500us.
