sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:34Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

Merge tag 'powerpc-4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

2017-02-22T18:30:38Z

Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for direct mapped LPC on POWER9, giving Linux direct access to devices that may be on there such as a UART. - Memory hotplug support for the Power9 Radix MMU. - Add new AUX vectors describing the processor's cache geometry, to be used by glibc. - The ability for a guest to ask the hypervisor to resize the guest's hash table, and in addition support for doing so automatically when memory is hotplugged into/out-of the guest. This allows the hash table to be sized based on the current memory usage of the guest, rather than the maximum possible memory usage. - Implementation of optprobes (kprobe optimisation) for powerpc. In addition there's the topic branch shared with the KVM tree, which includes support for guests to use the Radix MMU on Power9.

m68k/mac: Clean up interrupt debug macros and printk statements

2017-02-09T13:18:19Z

Mac interrupt code has been debugged. The Penguin deficiencies that still cause unhandled interrupts aren't fixable here. Besides, interrupts are fast and frequent and these printk statements were never really useful IMO. Remove them. Signed-off-by: Finn Thain Signed-off-by: Geert Uytterhoeven

m68k/mac: Remove SHUTUP_SONIC interrupt hack

2017-02-09T13:18:19Z

In macints.c there is some startup code which disables the SONIC interrupt in an attempt to avoid an unhandled slot interrupt, which would be fatal. This only works on those machines where the SONIC device is on-board. When the mac_sonic driver is built-in, there's little point in doing this, because the device will be initialized a few seconds later anyway. But when mac_sonic is a module, the window for an unhandled interrupt is longer. Either way, we've already run the gauntlet for 5 or 10 seconds by the time we get around to disabling this particular device. It's only by sheer luck that we got this far. Really, this is too little too late. The general problem of unhandled early interrupts also affects other devices on other models. There are better ways to resolve this problem. 1) When using the Penguin bootloader, boot Mac OS with extensions disabled (by holding down the shift key at startup or by use of the Extensions Manager control panel). The Penguin docs already contain this advice, as it is always effective. 2) Have the Penguin bootloader disable the device. It already attempts to disable slot interrupts. But since some hardware cannot mask slot interrupts, Penguin should probably close the relevant device drivers. 3) Use Emile instead of Penguin. AFAIK the boot ROM never enables network device interrupts and hence they don't need to be disabled. Remove this hack. It requires maintenance and it doesn't solve the problem. It improves the odds for a few models, but so does setting CONFIG_MAC_SONIC=y. Signed-off-by: Finn Thain Reviewed-by: Laurent Vivier Signed-off-by: Geert Uytterhoeven

m68k/mac: Improve NMI handler

2017-02-09T13:18:18Z

mac_nmi_handler() is useless in its present form and locks up my PowerBook 180. Let's throw out the dead code and make it do something useful: print a register dump and a stack trace. mac_debug_handler() is also dead code. Remove it along with its static data.
