[PATCH v2 00/27] x86: PIE support and option to extend KASLR randomization
Changes:
- patch v2:
- Adapt patch to work post KPTI and compiler changes
- Redo all performance testing with latest configs and compilers
- Simplify mov macro on PIE (MOVABS now)
- Reduce GOT footprint
- 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
