ppc/mmu_helper.c: do not truncate 'ea' in booke206_invalidate_ea_tlb()
'tlbivax' is implemented by gen_tlbivax_booke206() via
gen_helper_booke206_tlbivax(). In case the TLB needs to be flushed,
booke206_invalidate_ea_tlb() is called. All these functions, but
booke206_invalidate_ea_tlb(), uses a 64-bit effective address 'ea'.
booke206_invalidate_ea_tlb() uses an uint32_t 'ea' argument that
truncates the original 'ea' value for apparently no particular reason.
This function retrieves the tlb pointer by calling booke206_get_tlbm(),
which also uses a target_ulong address as parameter - in this case, a
truncated 'ea' address. All the surrounding logic considers the
effective TLB address as a 64 bit value, aside from the signature of
booke206_invalidate_ea_tlb().
Last but not the least, PowerISA 2.07B section 6.11.4.9 [2] makes it
clear that the effective address "EA" is a 64 bit value.
Commit 01662f3e5133 introduced this code and no changes were made ever
since. An user detected a problem with tlbivax [1] stating that this
address truncation was the cause. This same behavior might be the source
of several subtle bugs that were never caught.
For all these reasons, this patch assumes that this address truncation
is the result of a mistake/oversight of the original commit, and changes
booke206_invalidate_ea_tlb() 'ea' argument to 'vaddr'.

spapr_numa.c: fix FORM1 distance-less nodes
Commit 71e6fae3a99 fixed an issue with FORM2 affinity guests with NUMA
nodes in which the distance info is absent in
machine_state->numa_state->nodes. This happens when QEMU adds a default
NUMA node and when the user adds NUMA nodes without specifying the
distances.
During the discussions of the forementioned patch [1] it was found that
FORM1 guests were behaving in a strange way in the same scenario, with
the kernel seeing the distances between the nodes as '160', as we can
see in this example with 4 NUMA nodes without distance information:
Turns out that we have the same problem with FORM1 guests - we are
calculating associativity domain using zeroed values. And as it also
turns out, the solution from 71e6fae3a99 applies to FORM1 as well.
This patch creates a wrapper called 'get_numa_distance' that contains
the logic used in FORM2 to define node distances when this information
is absent. This helper is then used in all places where we need to read
distance information from machine_state->numa_state->nodes. That way
we'll guarantee that the NUMA node distance is always being curated
before being used.
After this patch, the FORM1 guest mentioned above will have the
following topology:

a node distance is smaller than the local distance.

The plan is to remove the call to the `check-avocado` target one

people to move to the new `check-avocado` target.
Later, the `check-acceptance` target can be removed. The intent
is to avoid a direct impact during the current soft freeze.

docs: remove non-reference uses of single backticks
The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.
This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.
Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.
