Subject: [S390] fix sparsemem related compile error with allnoconfig on s390
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=97195d6b411fec8e33aa55b6a7c3dde7984d65ca;p=deliverable%2Flinux.git

[S390] fix sparsemem related compile error with allnoconfig on s390

On s390 make allnoconfig fails with the following build error:

arch/s390/mm/init.c: In function 'show_mem':
arch/s390/mm/init.c:55: error: implicit declaration of function 'pfn_valid'
make[1]: *** [arch/s390/mm/init.o] Error 1
make: *** [arch/s390/mm] Error 2

This problem can by fixed ensuring that ARCH_SELECT_MEMORY_MODEL
is always turned on.
