    [PATCH] IPMI driver updates · 41556780
    Corey Minyard authored
    Some people found some bugs and some missing functions in the IPMI driver,
    so I have patching things together for the next release.  The attached
    patch moves to version 33 of the driver and contains:
    
    * SMBIOS table support for specifying register spacing.  This allows
      non-contiguous registers to be specified and some machines do
      this.
    * ACPI table updates to support all the possible register sizes and
      bit offsets into the registers for the IPMI information.
    * Support for command line parameters to specify register
      spacing, sizes, and bit offsets.
    * Support for power control with IPMI.  This allows a halt to
      power down a machine with IPMI.
    * A fix for a race condition with interrupts enabled on an
      SMP machine.  A lock was released then reclaimed, but
      there was code later that assumed that had not happened.
    * A fix for protecting the driver against bad responses from
      the controller chip.  In the past, the driver had assumed that
      the controller chip would not give it bad data.  This has
      turned out to be a bad assumption
    * ACPI interrupt handlers now return a return value, adjust
      accordingly.
    
    Thank you to all the people who helped me with this.
