Fix kernel oops due to machine check occuring in init_chipset_siimage() on PPC 44x platforms. These 32-bit CPUs have 36-bit physical address and PCI I/O and memory spaces are mapped beyond 4 GB; arch/ppc/ code has a fixup in ioremap() that creates an illusion of the PCI I/O and memory resources being mapped below 4 GB, while arch/powerpc/ code got rid of this fixup with PPC 44x having instead CONFIG_RESOURCES_64BIT=y -- this causes the resources to be truncated to 32-bit 'unsigned long' type in this driver, and so non-existant memory being ioremap'ed and then accessed... Thanks to Valentine Barshak for providing an initial patch and explanations. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> |
