#     powerpc: disable support for relative ksymtab references
#     
#     The newly added code that emits ksymtab entries as pairs of 32-bit
#     relative references interacts poorly with the way powerpc lays out its
#     address space: when a module exports a per-CPU variable, the primary
#     module region covering the ksymtab entry -and thus the 32-bit relative
#     reference- is too far away from the actual per-CPU variable's base
#     address (to which the per-CPU offsets are applied to obtain the
#     respective address of each CPU's copy), resulting in corruption when the
#     module loader attempts to resolve symbol references of modules that are
#     loaded on top and link to the exported per-CPU symbol.
#     
#     So let's disable this feature on powerpc.  Even though it implements
#     CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so
#     KASLR kernels (which are the main target of the feature) do not exist on
#     powerpc anyway.
