Subject: [PATCH 1/2] ARM: Remove redundant ARCH_SPARSEMEM_DEFAULT setting
Date: Wed, 6 May 2020 16:50:08 -0700 [thread overview]
Message-ID: <20200506235009.25023-2-f.fainelli@gmail.com> (raw)
In-Reply-To: <20200506235009.25023-1-f.fainelli@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.
