Subject[PATCH 1/2] x86/Kconfig: make SPARSEMEM default for 32-bit
Date
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.
