[PATCH v1 00/27] x86: PIE support and option to extend KASLR randomization
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

x86: PIE support and option to extend KASLR randomization
These patches make the changes necessary to build the kernel as Position
Independent Executable (PIE) on x86_64. A PIE kernel can be relocated below
the top 2G of the virtual address space. It allows to optionally extend the
KASLR randomization range from 1G to 3G.
Thanks a lot to Ard Biesheuvel & Kees Cook on their feedback on compiler
changes, PIE support and KASLR in general. Thanks to
