[PATCH v3] mm/thp: fix __split_huge_pmd_locked() for migration PMD
A migrating transparent huge page has to already be unmapped. Otherwise,
the page could be modified while it is being copied to a new page and
data could be lost. The function __split_huge_pmd() checks for a PMD
migration entry before calling __split_huge_pmd_locked() leading one to
think that __split_huge_pmd_locked() can handle splitting a migrating PMD.
However, the code always increments the

[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

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

[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
