Pull module_init replacement part one from Paul Gortmaker: "Replace module_init with equivalent device_initcall in non modules. This series of commits converts non-modular code that is using the module_init() call to hook itself into the system to instead use device_initcall(). The conversion is a runtime no-op, since module_init actually becomes __initcall in the non-modular case, and that in turn gets mapped onto device_initcall. A couple files show a larger negative diffstat, representing ones that had a module_exit function that we remove here vs previously relying on the linker to dispose of it. We make this conversion now, so that we can relocate module_init from init.h into module.h in the future. The files changed here are just limited to those that would otherwise have to add module.h to obviously non-modular code, in order to avoid a compile fail, as testing has shown" * tag 'module_init-device_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: MIPS: don't use module_init in non-modular cobalt/mtd.c file drivers/leds: don't use module_init in non-modular leds-cobalt-raq.c cris: don't use module_init for non-modular core eeprom.c code tty/metag_da: Avoid module_init/module_exit in non-modular code drivers/clk: don't use module_init in clk-nomadik.c which is non-modular xtensa: don't use module_init for non-modular core network.c code sh: don't use module_init in non-modular psw.c code mn10300: don't use module_init in non-modular flash.c code parisc64: don't use module_init for non-modular core perf code parisc: don't use module_init for non-modular core pdc_cons code cris: don't use module_init for non-modular core intmem.c code ia64: don't use module_init in non-modular sim/simscsi.c code ia64: don't use module_init for non-modular core kernel/mca.c code arm: don't use module_init in non-modular mach-vexpress/spc.c code powerpc: don't use module_init in non-modular 83xx suspend code powerpc: use device_initcall for registering rtc devices x86: don't use module_init in non-modular devicetree.c code x86: don't use module_init in non-modular intel_mid_vrtc.c

x86: don't use module_init in non-modular intel_mid_vrtc.c

2015-06-16T18:12:29+00:00

The X86_INTEL_MID option is bool, and hence this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of device_initcall directly in this change means that the runtime impact is zero -- it will remain at level 6 in initcall ordering.

x86/irq: Convert IOAPIC to use hierarchical irqdomain interfaces

2015-04-24T13:36:51+00:00

Convert IOAPIC driver to support and use hierarchical irqdomain interfaces. It's a little big, but would break bisecting if we split it into multiple patches. Fold in a patch from Andy Shevchenko to make it bisectable. http://lkml.org/lkml/2014/12/10/622 Signed-off-by: Jiang Liu Tested-by: Joerg Roedel Cc: Konrad Rzeszutek Wilk Cc: Sander Eikelenboom Cc: David Vrabel Cc: Tony Luck Cc: Joerg Roedel Cc: Greg Kroah-Hartman Cc: Andy Shevchenko Cc: sfi-devel@simplefirmware.org Cc: Bjorn Helgaas Cc: Benjamin Herrenschmidt Cc: Rafael J.

x86/irq: Prepare IOAPIC interfaces to support hierarchical irqdomains

2015-04-24T13:36:51+00:00

Introduce helper functions to manipulate struct irq_alloc_info for IOAPIC. Also add an extra parameter to IOAPIC interfaces to prepare for hierarchical irqdomain. Function mp_set_gsi_attr() will be removed once we have switched to hierarchical irqdomains.

x86/intel-mid: Delay initialization of APB timer

2015-04-24T13:36:51+00:00

MID has no PIC, but depending on the platform it requires the abt_timer, which is connected to irq0. The timer is set up at late_time_init(). But, looking at the MID code it seems, that there is no reason to do so. The only code which might need the timer working is the TSC calibration code, but thats a non issue on MID as that is using its own empty calibration function. And check_timer() is not invoked either because MID has no PIC and therefor no legacy irqs. So if you look at intel_mid_time_init() then you'll see that in the ARAT case the timer setup is skipped already. So until the point where x86_init.timers.setup_percpu_clockev() is called for the boot cpu nothing really needs a timer on MID. According to the MID code the apbt horror is only used for moorestown. Medfield and later use the local apic timer without the apbt nonsense. The best thing we can do is to drop moorestown support and get rid of that apbt nonsense alltogether. I don't think anyone deeply cares about it not being supported from 3.18 on. The number of devices which sport a moorestown should be pretty limited and the only relevant use case of those is to act as a pocket heater with short battery life time. Its pretty pointless to update kernels on pocket heaters except for bragging reasons. If someone at Intel really thinks that we need to keep moorestown alive for other than documentary and sentimental reasons, then we can move the apbt setup to x86_init.timers.setup_percpu_clockev(). At that point the IOAPIC is setup already, so it should just work.

x86, intel-mid: remove Intel MID specific serial support

2015-03-07T02:25:18+00:00

Since we have a native 8250 driver carrying the Intel MID serial devices the specific support is not needed anymore. This patch removes it for Intel MID.
