The existing generic touch code only reports events after reading an
entire HID report, which practically means that only data about the last
contact in a report will ever be provided to userspace. This patch uses
a trick from hid-multitouch.c to discover what type of field is at the
end of each contact; when such a field is encountered all the stored
contact data will be reported.

If a HID descriptor places HID_DG_CONTACTID before HID_DG_X and HID_DG_Y then
the ABS_X and ABS_Y will not be automatically initialized by the call to
input_mt_init_slots. To ensure that this is not a problem, we relocate that
call to occur after HID parsing has been completed and we've initalized all the
multitouch axes.

It is not necessarily sufficient to look only at the physical and logical
usages when determining if a field is for the pen or touch. Some fields
are not contained in a sub-collection and thus only have an application
usage. Not checking the application usage in such cases causes us to
ignore the field entirely, which may lead to incorrect behavior.

Provide the resolution of several angular axes (tilt, pen rotation, puck
rotation) to userspace. Because these values are natively degree-based, we
need to convert them to into units/radian as required by the input_absinfo
struct. To ensure wraparound behaves properly for the rotation axes, the
converted value was rounded up rather than rounded nearest.

Notably, the touchring axes (ABS_WHEEL and ABS_THROTTLE) are left without a
a declared resolution because the their low resolution cannot be accurately
represented (the worst-case rounding-induced error would be ~16 degrees).
Pre-scaling the values and range by at least 10x would reduce the error in
the resolution to acceptable levels, but the xf86-input-wacom driver is not
able to use pre-scaled values for these axes at this time.

Centers the ABS_TILT_{X,Y} axes so that a value of zero is reported when

The commit which introduced TransducerSerialNumber (368c9664) is missing
two crucial implementation details. Firstly, the commit does not set the
type/code/bit/max fields as expected later down the code which can cause
the driver to crash when a tablet with this usage is connected. Secondly,
the call to 'set_bit' causes MSC_PULSELED to be sent instead of the
expected MSC_SERIAL. This commit addreses both issues.

When unmapping a range of pages in zap_pte_range, the page being
unmapped is added to an mmu_gather_batch structure for asynchronous
freeing. If we run out of space in the batch structure before the range
has been completely unmapped, then we break out of the loop, force a
TLB flush and free the pages that we have batched so far. If there are
further pages to unmap, then we resume the loop where we left off.

Unfortunately, we forget to update addr when we break out of the loop,
which causes us to truncate the range being invalidated as the end
address is exclusive. When we re-enter the loop at the same address, the
page has already been freed and the pte_present test will fail, meaning
that we do not reconsider the address for invalidation.

This patch fixes the problem by incrementing addr by the PAGE_SIZE
before breaking out of the loop on batch failure.

In certain circumstances the PSL (Power Service Layer, which provides
translation services for CXL hardware) can send an interrupt for a
segment miss that the kernel has already handled. This can happen if
multiple translations for the same segment are queued in the PSL before
the kernel has restarted the first translation.

The CXL driver does not expect this situation and does not check if a
segment had already been handled. This could cause a duplicate segment
table entry which in turn caused a PSL error taking down the card.

This patch fixes the issue by checking for existing entries in the
segment table that match the segment we are trying to insert, so as to
avoid inserting duplicate entries.

This patch makes copro_calculate_slb() mask the ESID by the correct mask
for 1T vs 256M segments.

This has no effect by itself as the extra bits were ignored, but it
makes debugging the segment table entries easier and means that we can
directly compare the ESID values for duplicates without needing to worry
about masking in the comparison.

This will be used to simplify a comparison in the following patch.

This moves the segment table hash calculation from cxl_load_segment()
into find_free_sste() since that is the only place it is actually used.

This patch simplifies the process of finding a free segment table entry
by disabling the secondary hash. This reduces the number of possible
entries in the segment table for a given address from 16 to 8.

Due to the large segment sizes we use it is extremely unlikely that the
secondary hash would ever have been used in practice, so this should not
have any negative impacts and may even improve performance due to the
reduced number of comparisons that software & hardware need to perform.

This patch clears the SC bit in the hardware's state register
(CXL_PSL_SR_An) to disable the secondary hash in the hardware since we
can no longer fill out entries using it.

Ben says although the code is not correct "[this] fix was completely
wrong and does more damages than it fixes things."
