CRIS: Drop support for the CRIS port

2018-03-16T09:56:05Z

The port was added back in 2000 so it's no longer even a good source of inspiration for newer ports (if it ever was) The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008. Coupled with time and working developer board hardware being in low supply, it's time to drop the port from Linux. So long and thanks for all the fish!

Pull clk updates from Stephen Boyd: "The core framework has a handful of patches this time around, mostly due to the clk rate protection support added by Jerome Brunet. This feature will allow consumers to lock in a certain rate on the output of a clk so that things like audio playback don't hear pops when the clk frequency changes due to shared parent clks changing rates. Currently the clk API doesn't guarantee the rate of a clk stays at the rate you request after clk_set_rate() is called, so this new API will allow drivers to express that requirement. Beyond this, the core got some debugfs pretty printing patches and a couple minor non-critical fixes. Looking outside of the core framework diff we have some new driver additions and the removal of a legacy TI clk driver. Both of these hit high in the dirstat. Also, the removal of the asm-generic/clkdev.h file causes small one-liners in all the architecture Kbuild files. Overall, the driver diff seems to be the normal stuff that comes all the time to fix little problems here and there and to support new hardware.

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

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

2017-07-09T18:43:24Z

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. Also, move "generic-y += kprobes.h", "generic-y += emergency-restart.h" up in order to keep the entries sorted. 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.

kprobes: move kprobe declarations to asm-generic/kprobes.h

2017-02-28T02:43:45Z

Often all is needed is these small helpers, instead of compiler.h or a full kprobes.h. This is important for asm helpers, in fact even some asm/kprobes.h make use of these helpers... instead just keep a generic asm file with helpers useful for asm code with the least amount of clutter as possible. Likewise we need now to also address what to do about this file for both when architectures have CONFIG_HAVE_KPROBES, and when they do not. Then for when architectures have CONFIG_HAVE_KPROBES but have disabled CONFIG_KPROBES. Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES, this means most architecture code cannot include asm/kprobes.h safely. Correct this and add guards for architectures missing them. Additionally provide architectures that not have kprobes support with the default asm-generic solution. This lets us force asm/kprobes.h on the header include/linux/kprobes.h always, but most importantly we can now safely include just asm/kprobes.h on architecture code without bringing the full kitchen sink of header files. Two architectures already provided a guard against CONFIG_KPROBES on its kprobes.h: sh, arch. The rest of the architectures needed gaurds added. We avoid including any not-needed headers on asm/kprobes.h unless kprobes have been enabled. In a subsequent atomic change we can try now to remove compiler.h from include/linux/kprobes.h. During this sweep I've also identified a few architectures defining a common macro needed for both kprobes and ftrace, that of the definition of the breakput instruction up. Some refer to this as BREAKPOINT_INSTRUCTION. This must be kept outside of the #ifdef CONFIG_KPROBES guard.

Given that the arch does not add its own implementations, simply use the asm-generic/current.h (generic-y) header instead of duplicating code.

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 .
