Revert "ipmi: add new IPMI nmi watchdog handling"

2007-05-14T22:24:24+00:00

This reverts commit f64da958dfc83335de1d2bef9d3868f30feb4e53.

Andi Kleen is unhappy with the changes, and they really do not seem
worth it.  IPMI could use DIE_NMI_IPI instead of the new callback, even
though that ends up having its own set of problems too, mainly because
the IPMI code cannot really know the NMI was from IPMI or not.

Manually fix up conflicts in arch/x86_64/kernel/traps.c and
drivers/char/ipmi/ipmi_watchdog.c.

IPMI: Add PPC openfirmware unregister

2007-05-12T17:55:40+00:00

When trying to load the ipmi_si module on a powerpc with no BMC (baseboard
management controller) the driver failes to load correctly, but doesn't
unregister itself from of_platform.  So, on a second modprobe the kernel
crashes.  This patch adds the missing unregister call.

IPMI: fix SI address space settings

2007-05-12T17:55:40+00:00

Fix a rather obvious error that Patrick found in the setup routines.  Need to
set the proper address space in the ACPI case.

[S390] Kconfig: menus with depends on HAS_IOMEM.

2007-05-10T13:46:07+00:00

Add "depends on HAS_IOMEM" to a number of menus to make them
disappear for s390 which does not have I/O memory.

no longer #include

2007-05-08T18:15:20+00:00

Include the new linux/kdebug.h instead of asm/kdebug.h.

Simply remove the asm/kdebug.h include if both had been included.

move die notifier handling to common code

2007-05-08T18:15:04+00:00

This patch moves the die notifier handling to common code.  Previous
various architectures had exactly the same code for it.  Note that the new
code is compiled unconditionally, this should be understood as an appel to
the other architecture maintainer to implement support for it aswell (aka
sprinkling a notify_die or two in the proper place)

arm had a notifiy_die that did something totally different, I renamed it to
arm_notify_die as part of the patch and made it static to the file it's
declared and used at.  avr32 used to pass slightly less information through
this interface and I brought it into line with the other architectures.

ipmi: add pci remove handling

2007-05-08T18:14:58+00:00

Add pci_remove handling to the driver, so it will clean up if
the device is hot-removed.

ipmi: add new IPMI nmi watchdog handling

2007-05-08T18:14:58+00:00

Convert over to the new NMI handling for getting IPMI watchdog timeouts via an
NMI.  This add config options to know if there is the ability to receive NMIs
and if it has an NMI post processing call.  Then it modifies the IPMI watchdog
to take advantage of this so that it can know if an NMI comes in.

It also adds testing that the IPMI NMI watchdog works.

ipmi: allow shared interrupts

2007-05-08T18:14:58+00:00

The IPMI driver used enable_irq and disable_irq when it got into situations
where it couldn't allocate memory; it did this to avoid having the interrupt
just lock the machine when it couldn't get memory to perform the transaction
to disable the interrupt.

This patch modifies the driver to not use disable_irq and enable_irq.  It
instead sends the messages to the BMC to perform this operation.  It also
makes sure interrupts are cleanly disabled when the interface is shut down and
cleans up some shutdown things that are no longer necessary.

ipmi: add powerpc openfirmware sensing

2007-05-08T18:14:58+00:00

Add support for of_platform_driver to the ipmi_si module.  When loading the
module, the driver will be registered to of_platform.  The driver will be
probed for all devices with the type ipmi.  It's supporting devices with
compatible settings ipmi-kcs, ipmi-smic and ipmi-bt.  Only ipmi-kcs could be
tested.
