Switch to the generic noncoherent direct mapping implementation. Signed-off-by: Christoph Hellwig Acked-by: Yoshinori Sato

time: Add an asm-generic/compat.h file

2018-04-19T11:28:51Z

We have a couple of files that try to include asm/compat.h on architectures where this is available. Those should generally use the higher-level linux/compat.h file, but that in turn fails to include asm/compat.h when CONFIG_COMPAT is disabled, unless we can provide that header on all architectures. This adds the asm/compat.h for all remaining architectures to simplify the dependencies. Architectures that are getting removed in linux-4.17 are not changed here, to avoid needless conflicts with the removal patches. Those architectures are broken by this patch, but we have already shown that they have no users. Signed-off-by: Arnd Bergmann

arch: Remove clkdev.h asm-generic from Kbuild

2018-01-03T17:02:11Z

Now that every architecture is using the generic clkdev.h file and we no longer include asm/clkdev.h anywhere in the tree, we can remove it. Cc: Russell King Acked-by: Arnd Bergmann Cc: Acked-by: Geert Uytterhoeven [m68k] Signed-off-by: Stephen Boyd

sh: move generic-y of exported headers to uapi/asm/Kbuild

2017-07-11T12:33:51Z

Since commit fcc8487d477a ("uapi: export all headers under uapi directories"), all (and only) headers under uapi directories are exported, but asm-generic wrappers are still exceptions. To complete de-coupling the uapi from kernel headers, move generic-y of exported headers to uapi/asm/Kbuild. With this change, "make headers_install" will just need to parse uapi/asm/Kbuild to build up exported headers. Signed-off-by: Masahiro Yamada

signal: Remove non-uapi

2017-06-04T13:11:47Z

By moving the kernel side __SI_* defintions right next to the userspace ones we can kill the non-uapi versions of include include/asm-generic/siginfo.h and untangle the unholy mess of includes.

sched/cputime: Remove generic asm headers

2017-02-01T08:14:07Z

cputime_t is now only used by two architectures: * powerpc (when CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y) * s390 And since the core doesn't use it anymore, we don't need any arch support from the others. So we can remove their stub implementations. A final cleanup would be to provide an efficient pure arch implementation of cputime_to_nsec() for s390 and powerpc and finally remove include/linux/cputime.h .

locking/rwsem, sh: Drop superfluous arch specific implementation

2016-04-13T08:42:19Z

Since "locking, rwsem: drop explicit memory barriers" the arch specific code is basically same as the the generic one so we can drop the superfluous code.

sh: Use generic clkdev.h header

2016-03-17T19:45:13Z

The generic header file is almost equivalent to the SH one. The only difference is that the SH one supports allocating clkdev lookups early using bootmem allocators instead of the slabs. From what I can tell using visual inspection, the slab is initialized before any clkdev allocation is made under arch/sh. So let's remove the arch specific clkdev.h header and use the generic one instead. Signed-off-by: Stephen Boyd Signed-off-by: Rich Felker

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.
