arm: Drop sp from clobber list
This gives
warning: listing the stack pointer register ‘sp’ in a clobber list is
deprecated
note: the value of the stack pointer after an ‘asm’ statement must be the
same as it was before the statement
with gcc 9. Obviously, this cannot be fulfilled in the given case as it
is one of the purposes of the assembly block. But as there is no code
after it anyway, it's safe to drop sp from the clobbering list.

The Linux kernel commit c55af7f719cb writes:
"Such a mismatch could be intentional (to fix wrong register values).
If its not intentional (e.g. due to wrong DT information) this will
very likely cause a malfunction of the driver as SMMU_CB_BASE is
derived from the size of the mapped region. The warning helps to
identify the root cause in this case."

It's a bit wasteful, but the alternative can be that the guest moves the

sub-page dispatching. That is first of all a source for mistakes
(specifically in combination with generated configs), and it may even be
suboptimal in case exceeding, full-page access on that physical region

arm64: smmu: Refactor smmu device setup and usage
We only need iommu_units from the system configuration during setup.
Afterwards, we work solely against entries of smmu_device.
Rework the usage of the latter by filling the smmu_device array
independently of the iommu_units and iterating over the former later on.
Introduce an iterator macro for this. Helps to simplify the code.

We do not handle faults, e.g. by resuming them later on. Stalling
failed transactions will soon lead to a stalled SMMU, blocking even
valid transactions.
This could easily be reproduced by stealing a used StreamID from the
root cell. On the Zynqmp, this lead to all transactions of the root cell
to be blocked.

arm64: smmu: Refactor S2CR handling
There is no need to cache the value we write to S2CRn. Drop the related
data structure and pass the values to be written to arm_smmu_write_s2cr
directly. This implies dropping arm_smmu_write_sme, open-coding it.
Still a net gain as a lot of boilerplate code can be dropped.
Along this cleanup, convert arm_smmu_s2cr_type and arm_smmu_s2cr_privcfg
into defines, only encoding what we use. There is no value in enums.

inmates: x86: add cache access time test
On x86_64 systems, this test inmate measures the time that is required to read
a value from main memory. Via rdtsc, it measures the CPU cycles that are
required for the access. Access can either happen cached, or uncached. In case
of uncached access, the cache line will be flushed before access.
This tool repeats the measurement for 10e6 times, and outputs the
average cycles that were required for the access. Before accessing the
actual measurement, a dummy test is used to determine the average
overhead of one single measurement.
And that's pretty useful, because this tool gives a lot of insights of
differences between the root and the non-root cell: With tiny effort, we
can also run it on Linux.
If the 'overhead' time differs between root and non-root cell, this can
be an indicator that there might be some timing or speed differences
between the root and non-root cell.
If the 'uncached' or 'cached' average time differs between the non-root
and root cell, it's an indicator that both might have different hardware
configurations / setups.
