ARM: 8979/1: Remove redundant ARCH_SPARSEMEM_DEFAULT setting
Browse files Browse the repository at this point in the history 
If ARCH_SPARSEMEM_ENABLE=y and ARCH_{FLATMEM,DISCONTIGMEM}_ENABLE=n,
then the logic in mm/Kconfig already makes CONFIG_SPARSEMEM the only
choice.  This is true for all of the existing ARM users of
ARCH_SPARSEMEM_ENABLE.

Forcing ARCH_SPARSEMEM_DEFAULT=y if ARCH_SPARSEMEM_ENABLE=y prevents
us from ever defaulting to FLATMEM, so we should remove this setting.
