I''m afraid this series is rather a grab bag and it is distressingly large at this stage. With this series I can boot an Xgene board until it fails to find its SATA controller. This is a dom0 issue for which patches are pending from APM (/me nudges Anup). As well as the APM specific platform stuff there are also some generic improvements which were either necessary or useful during this

George has release acked all of these. Otherwise mostly minor updates this time around. Summary: A == acked, M == modified A xen: arm64: Add 8250 earlyprintk support A xen: arm64: Add Basic Platform support for APM X-Gene Storm. A xen: arm64: Add APM implementor id to processor implementers. M xen: arm: add a quirk to handle platforms with unusual GIC layout A xen: arm: allow platform

Andrey, I believe that on Xen we should disable kasan, would like confirmation from someone on xen-devel though. Here's the thing though -- if true -- I'd like to do it *properly*, where *properly* means addressing a bit of architecture. A simple Kconfig slap seems rather reactive. I'd like to address a way to properly ensure we don't run into this and other similar issues in the

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

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

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

Fix several warnings and broken links. This series was generated against linux-next, but was rebased to be applied at docs-next. It should apply cleanly on either tree.
