Add full driver model support for the IPMI driver. It links in the proper bus and device support. It adds an "ipmi" driver interface that has each BMC discovered by the driver (as a device). These BMCs appear in the devices/platform directory. If there are multiple interfaces to the same BMC, the driver should discover this and will only have one BMC entry. The BMC entry will have pointers to each interface device that connects to it. The device information (statistics and config information) has not yet been ported over to the driver model from proc, that will come later. This work was based on work by Yani Ioannou. I basically rewrote it using that code as a guide, but he still deserves credit :).

Modify the PCI hanling code for the IPMI driver to use the new method of tables and registering, and adds more generic PCI handling for IPMI. Unfortunately, this required a rather large rework of the way the driver did detection so it would be more event-driven.

At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide default register spacings in try_init_acpi() if the register spacing was set to zero, similar to code in other routines. Unfortunately, another patch was simultaneously added that exits early from try_init_acpi() if the register spacings are set to zero, circumventing the new defaults. This patch removes the early exit code and some incorrect comments that aren't present in other common code snippets.

With Andi Kleen's x86_64 patch to use DMI, and my ia64 to use DMI, there is now a new CONFIG_DMI option which takes the place of CONFIG_X86 to denote the availability of the DMI functions. Make the IPMI driver use CONFIG_DMI instead. Tested on ia64 2.6.15 kernel plus the previous patch, on a Dell PowerEdge 7250 Itanium2 server, and it now autodetects the IPMI KCS driver as expected.

While doing some testing I discovered that if the BIOS on a board does not properly setup the DMI information it leads to a panic in the IPMI code. The panic is due to dereferencing a pointer which is not initialized. The pointer is initialized in port_setup() and/or mem_setup() and used in init_one_smi() and cleanup_one_si(), however if either port_setup() or mem_setup() return ENODEV the pointer does not get initialized.

We must poll for responses to commands when interrupts aren't in use. The default poll interval is based on using a kernel timer, which varies with HZ. For character-based interfaces like KCS and SMIC though, that can be way too slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve the sensor list). This creates a low-priority kernel thread to poll more often. If the state machine is idle, so is the kernel thread. But if there's an active command, it polls quite rapidly. This decrease a firmware flash time from 15 minutes to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge x8x system. The timer-based polling remains, to ensure some amount of responsiveness even under high user process CPU load. Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to ensure safe stoppage.

BMCs can get into ERROR0 state while flashing new firmware, particularly while the BMC is erasing the next flash block, which may take a just under 2 seconds on a Dell PowerEdge 2800 (1.75 seconds typical), during which time the single-threaded firmware may not be able to process new commands. In particular, clearing OBF may not take effect immediately. We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to actually be clear before proceeding. This introduces a new return value from the LLDD's event loop, SI_SM_CALL_WITH_TICK_DELAY. This means the calling thread/timer should schedule_timeout() at least 1 tick, rather than busy-wait. This is a longer delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

Some commands, on some system BMCs, don't respond at at all. This is seen on Dell PowerEdge x6xx and x7xx systems with IPMI 1.0 BT controllers when a "Get SDR" command is issued, with a length field of 0x3A, which happens to be the length of about SDR entries. If another length is passed, this command succeeds. This patch adds general infrastructure for receiving commands before they're passed down to the low-level drivers, such that they can be completed immediately, or modified, prior to being sent to ->start_transaction().

Make the OEM0 Data Available handler work for pre-IPMI 1.5 systems from Dell too.

A number of small changes for the various system interface drivers, consolidated from a number of patches from Matt Domsch. Clear B2H_ATN and drain the BMC message buffer on command timeout. This prevents further commands from failing after a timeout. Add bt_debug and smic_debug module parameters, expose them in sysfs. This lets you enable and disable debugging messages at runtime. Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed to ->event() after jiffies wrap-around. The BT driver had caught this, but didn't know how to fix it. Now all calls to ->event() use a sane value for time. Increase timeout for commands handed to the BT driver from 2 seconds to 5 seconds. This is necessary particularly when the previous command was a "Clear SEL", as that command completes, yet the BMC isn't really ready to handle another command yet. Silence BT debugging messages which were being printed on the console. Increase SMIC timeout form 1/10s to 2s. This is needed on Dell PowerEdge 2650 and PowerEdge 750 with ERA/O cards to allow commands to complete without timing out. Adds kcs_debug module param, to match behavior of BT and SMIC. This also prevents messages from being sent to the console unless explicitly requested.

The ipmi driver does not have a way to handle firmware-generated events which have the OEM[012] Data Available flags set. In such a case, the SMS_ATN bit may never get cleared by firmware, leaving the driver looping infinitely but never able to make any progress. This patch first simplifies storage and use of the data returned from an IPMI Get Device ID command. It then creates a new per-OEM handler hook, which should know how to handle events with the OEM[012] Data Available flags set. It then uses this to implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which are susceptable to setting the OEM[012] Data Available flags when the driver can't handle it.

`gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files).

Enable interrupts for a BT interface. There is a specific register that needs to be set up to enable interrupts that also must be modified to clear the irq. Also, don't reset the BMC on a BT interface. That's probably not a good idea as the BMC may be performing other important functions and a reset should only be a last resort. Also, that register is also used to enable/disable interrupts to the BT; modifying it may screw up the interrupts.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
