similar to: [PATCH v11 00/11] x86: PIE support to extend KASLR randomization

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

Changes: - patch v5: - Adapt new crypto modules for PIE. - Improve per-cpu commit message. - Fix xen 32-bit build error with .quad. - Remove extra code for ftrace. - patch v4: - Simplify early boot by removing global variables. - Modify the mcount location script for __mcount_loc intead of the address read in the ftrace implementation. - Edit commit description to

Changes: - patch v4: - Simplify early boot by removing global variables. - Modify the mcount location script for __mcount_loc intead of the address read in the ftrace implementation. - Edit commit description to explain better where the kernel can be located. - Streamlined the testing done on each patch proposal. Always testing hibernation, suspend, ftrace and kprobe to

Changes: - patch v1: - Simplify ftrace implementation. - Use gcc mstack-protector-guard-reg=%gs with PIE when possible. - rfc v3: - Use --emit-relocs instead of -pie to reduce dynamic relocation space on mapped memory. It also simplifies the relocation process. - Move the start the module section next to the kernel. Remove the need for -mcmodel=large on modules. Extends
