[Xen-devel] L1TF Patch Series v8

[Norbert Manthey <nmanthey@xxxxxxxxx>]

This patch series attempts to mitigate the issue that have been raised in the
XSA-289 (https://xenbits.xen.org/xsa/advisory-289.html). To block speculative
execution on Intel hardware, an lfence instruction is required to make sure
that selected checks are not bypassed. Speculative out-of-bound accesses can
be prevented by using the array_index_nospec macro.

The major change compared to version 8 is in grant_table handling, protecting
a few more version comparisons.

Best,
Norbert
