Subject: [PATCH 1/2] x86/Kconfig: make SPARSEMEM default for 32-bit
Date: Wed, 24 Apr 2019 16:24:11 +0300 [thread overview]
Message-ID: <1556112252-9339-2-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1556112252-9339-1-git-send-email-rppt@linux.ibm.com>
Sparsemem has been a default memory model for x86-64 for over a decade
since the commit b263295dbffd ("x86: 64-bit, make sparsemem vmemmap the
only memory model").
Make it the default for 32-bit NUMA systems (if there any left) as well.
Signed-off-by: Mike Rapoport <rppt@linux.ibm.com>
