The original implementation of MMC support for Akebono introduced a
new configuration symbol (MMC_SDHCI_OF_476GTR). This symbol has been
dropped in favour of using the generic platform driver however the
select for this symbol was mistakenly left in the platform
configuration.

The arch/powerpc/include/asm/linkage.h is being unintentionally exported
in the kernel headers since commit e1b5bb6d1236 (consolidate
cond_syscall and SYSCALL_ALIAS declarations) when

removed from the Kbuild file. This happens
