2014-03-31MIPS: SEAD3: Don't use module_init in non-modular sead3-mtd.c codePaul Gortmaker
The sead3-mtd.o is built for obj-y -- and hence this code is always present. It will never be modular, so using module_init as an alias for __initcall can be somewhat 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. We also fix a missing semicolon, which this change uncovers.

Loongson-1 is a 32-bit MIPS CPU and Loongson-2/3 are 64-bit MIPS CPUs, and both Loongson-2/3 has the same PRID IMP filed (0x6300).

2014-03-31watchdog: Fix Elan SC520 dependenciesJean Delvare
Anyone using a system based on an AMD Elan SC520 processor would be building a dedicated kernel for it, so we can make the sc520_wdt driver depend on MELAN. SC520_CPUFREQ already depends on MELAN so it makes things more consistent. It also makes kernel configuration for every other x86 user easier.

2014-03-31watchdog: it87_wdt: Work around non-working CIR interruptsMarc van der Wal
On some hardware platforms, the it87_wdt watchdog resets the machine despite the watchdog daemon running and writing to /dev/watchdog. This is due to Consumer IR buffer underrun interrupts being used as triggers to reset the timer. On some buggy hardware implementations such as the iEi AFL-12A-N270 single-board computer, this method does not work. However, resetting the timer by writing its original timeout value in its configuration register over and over again suppresses the unwanted reboots. Add a module option (nocir), 0 by default in order not to break existing setups. Setting it to 1 enables the workaround. Fixes bug #42801 <https://bugzilla.kernel.org/show_bug.cgi?id=42801>. Tested primarily on Linux 3.5.7, applies cleanly on Linux 3.13.5.
