This patch adds tracepoints throughout the cxl driver, which can provide
insight into:
- Context lifetimes
- Commands sent to the PSL and AFU and their completion status
- Segment and page table misses and their resolution
- PSL and AFU interrupts
- slbia

I noticed ksm spending quite a lot of time in memcmp on a large
KVM box. The current memcmp loop is very unoptimised - byte at a
time compares with no loop unrolling. We can do much much better.
Optimise the loop in a few ways:
- Unroll the byte at a time loop

The number of I2C adapters which are not fully I2C compatible is rising,
sadly. Drivers usually do handle the flaws, still the user receives only
some errno for a transfer which normally can be expected to work. This
patch introduces a formal description of flaws. One advantage is that

Recently, a number of submitted I2C master drivers could not fully handle all
I2C type transfers due to limited HW. So, they had to bail out with some errno
although the user supplied a valid I2C transfer. In order to centralize such
quirks, a central structure describing the quirks is introduced.
Let the core do the checks if HW quirks prevent a transfer. Saves code
from drivers and adds consistency.
