Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc
Pull sparc updates from David Miller:
1) Debugging builds on 32-bit sparc need to handle the R_SPARC_DISP32
relocation, not just 64-bit sparc. From Andreas Larsson.
2) Wei Yongjun noticed that module_alloc() on sparc can return an
error pointer, but that's not allowed. module_alloc() should
return only a valid pointer, or NULL.
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
sparc: fix the return value of module_alloc()
sparc32: Enable the relocation target R_SPARC_DISP32 for sparc32
