    sparc64: Fix crash with /proc/iomem · 192d7a46
    Mikulas Patocka authored
    When you compile kernel on Sparc64 with heap memory checking and type
    "cat /proc/iomem", you get a crash, because pointers in struct
    resource are uninitialized.
    Most code fills struct resource with zeros, so I assume that it is
    responsibility of the caller of request_resource to initialized it,
    not the responsibility of request_resource functuion.
    After 2.6.29 is out, there could be a check for uninitialized fields
    added to request_resource to avoid crashes like this.
