arm64: Remove shadowed asm-generic headers

2016-09-09T14:05:08Z

We've grown our own versions of bug.h, ftrace.h, pci.h and topology.h, so generating the generic ones as well is unnecessary and a potential source of build hiccups. At the very least, having them present has confused my source-indexing tool, and that simply will not do. Signed-off-by: Robin Murphy Signed-off-by: Will Deacon

arm64: Create sections.h

2016-08-25T17:00:29Z

Each time new section markers are added, kernel/vmlinux.ld.S is updated, and new extern char __start_foo[] definitions are scattered through the tree. Create asm/include/sections.h to collect these definitions (and include the existing asm-generic version).

arm64: Implement optimised IP checksum helpers

2016-06-21T14:09:11Z

AArch64 is capable of 128-bit memory accesses without alignment restrictions, which makes it both possible and highly practical to slurp up a typical 20-byte IP header in just 2 loads. Implement our own version of ip_fast_checksum() to take advantage of that, resulting in considerably fewer instructions and memory accesses than the generic version. We can also get more optimal code generation for csum_fold() by defining it a slightly different way round from the generic version, so throw that into the mix too.

ARM64: PCI: Remove generated include of asm-generic/pci-bridge.h

2016-02-05T22:29:12Z

arm64 generates asm/pci-bridge.h, which merely includes the now-empty asm-generic/pci-bridge.h. Stop generating asm/pci-bridge.h, and stop including it. Signed-off-by: Bjorn Helgaas Acked-by: Will Deacon

mm: clean up per architecture MM hook header files

2015-07-17T23:39:53Z

Commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty header file (mm-arch-hooks.h) for every architecture, even those which doesn't need to define mm hooks. As suggested by Geert Uytterhoeven, this could be cleaned through the use of a generic header file included via each per architecture asm/include/Kbuild file. The PowerPC architecture is not impacted here since this architecture has to defined the arch_remap MM hook.

net, lib: kill arch_fast_hash library bits

2014-12-10T20:17:46Z

As there are now no remaining users of arch_fast_hash(), lets kill it entirely. This basically reverts commit 71ae8aac3e19 ("lib: introduce arch optimized hash library") and follow-up work, that is f.e., commit 237217546d44 ("lib: hash: follow-up fixups for arch hash"), commit e3fec2f74f7f ("lib: Add missing arch generic-y entries for asm-generic/hash.h") and last but not least commit 6a02652df511 ("perf tools: Fix include for non x86 architectures").

arm64: PCI/MSI: Use asm-generic/msi.h

2014-11-26T15:55:11Z

In order to support CONFIG_GENERIC_MSI_IRQ_DOMAIN, we need to define msi_alloc_info_t. As the generic version exposed in asm-generic/msi.h is perfectly convenient, import this file as asm/msi.h.
