Subject: [PATCH 2/3] ARM: Remove redundant ARCH_SPARSEMEM_DEFAULT setting
Date: Thu,  4 Jun 2015 18:58:37 -0700	[thread overview]
Message-ID: <1433469518-8472-3-git-send-email-gregory.0xf0@gmail.com> (raw)
In-Reply-To: <1433469518-8472-1-git-send-email-gregory.0xf0@gmail.com>

From: Kevin Cernekee <cernekee@gmail.com>

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.
