Splitting the previous serie in two. This part contains assembly code changes required for PIE but without any direct dependencies with the rest of the patchset. Changes: - patch v7 (assembly): - Split patchset and reorder changes. - patch v6: - Rebase on latest changes in jump tables and crypto. - Fix wording on couple commits. - Revisit checkpatch warnings. - Moving to

...any error. But of course this does not mean the model was correctly designed. Am I right when I'm doing this or am I (most likely) completely wrong? Thanks in advance for your help.

Minor changes based on feedback and rebase from v9. Splitting the previous serie in two. This part contains assembly code changes required for PIE but without any direct dependencies with the rest of the patchset. Changes: - patch v10 (assembly): - Swap rax for rdx on entry/64 changes based on feedback. - Addressed feedback from Borislav Petkov on boot, paravirt, alternatives and
