The commit 712b6aa8 [Nov7 linux-next via tip/auto-latest] ("intel_mid: Renamed *mrst* to *intel_mid*") adds a __cpuinit. We removed this a couple versions ago; we now want to remove the compat no-op stubs. Introducing new users is not what we want to see at this point in time, as it will break once the stubs are gone.

As Intel rolling out more SoC's after Moorestown, we need to re-structure the code in a way that is backward compatible and easy to expand. This patch implements a flexible way to support multiple boards and devices. This patch does not add any new functional support. It just refactors the existing code to increase the modularity and decrease the code duplication for supporting multiple soc's and boards. Currently intel-mid.c has both board and soc related code in one file. This patch moves the board related code to new files and let linker script to create SFI devite table following this: 1. Move the SFI device specific code to arch/x86/platform/intel-mid/device-libs/platform_<device>.* A new device file is added for every supported device. This code will get conditionally compiled by using corresponding device driver CONFIG option. 2. Move the device_ids location to .x86_intel_mid_dev.init section by using new sfi_device() macro. This patch was based on previous code from Sathyanarayanan Kuppuswamy.

mrst is used as common name to represent all intel_mid type soc's. But moorsetwon is just one of the intel_mid soc. So renamed them to use intel_mid. This patch mainly renames the variables and related functions that uses *mrst* prefix with *intel_mid*. To ensure that there are no functional changes, I have compared the objdump of related files before and after rename and found the only difference is symbol and name changes.

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/x86 uses of the __cpuinit macros from all C files. x86 only had the one __CPUINIT used in assembly files, and it wasn't paired off with a .previous or a __FINIT, so we can delete it directly w/o any corresponding additional change there.

Moorestown/Medfield platform does not have port 0x61 to report NMI status, nor does it have external NMI sources. The only NMI sources are from lapic, as results of perf counter overflow or IPI, e.g. NMI watchdog or spin lock debug. Reading port 0x61 on Moorestown will return 0xff which misled NMI handlers to false critical errors such memory parity error. The subsequent ioport access for NMI handling can also cause undefined behavior on Moorestown. This patch allows kernel process NMI due to watchdog or backrace dump without unnecessary hangs.

Moorestown systems crash on boot because the secondary CPU clockevent (apbt1) will fail to request irq#1, which does not have ioapic chip in its irq_desc[] entry. Background: Moorestown platform does not have ISA bus nor legacy IRQs. It reuses the range of legacy IRQs for regular device interrupts. The routing information of early system device IRQs (timers) are obtained from firmware provided SFI tables. We reuse/fake MP configuration table to facilitate IRQ setup with IOAPIC. Maintaining a 1:1 mapping of IOAPIC pin (RTE entry) and IRQ# makes routing information clean and easy to understand on Moorestown. Though optional. This patch allows SFI timer and vRTC IRQ to be treated as ISA IRQ so that pin2irq mapping will be 1:1. Also fixed MP table type and use macros to clearly set MP IRQ entries. As a result, apbt timer and RTC interrupts on Moorestown are within legacy IRQ range: # cat /proc/interrupts CPU0 CPU1 0: 11249 0 IO-APIC-edge apbt0 1: 0 12271 IO-APIC-edge apbt1 8: 887 0 IO-APIC-fasteoi dw_spi 13: 0 0 IO-APIC-fasteoi INTEL_MID_DMAC2 14: 0 0 IO-APIC-fasteoi rtc0 Further discussion of this patch can be found at: https://lkml.org/lkml/2010/6/10/70Suggested-by: N"Eric W.

When setting up the mpc_intsrc structure for vRTC's IRQ, we need to set its irqflag to level trigger, otherwise it will be taken as edge triggered and the vRTC IRQ will fire only once, as there is never a EOI issued from the IA core for it. The original code worked in previous kernel. This is because it was configured to level trigger type by luck. It fell into the default PCI trigger category which is level triggered.
