Subject[PATCH] mm: Remove duplicate definitions of MADV_FREE
Date
Commits 21f55b018ba5 ("arch/*/include/uapi/asm/mman.h: : let MADV_FREE
have same value for all architectures") and ef58978f1eaa ("mm: define
MADV_FREE for some arches") both defined MADV_FREE, but did not use the
same values. This results in build errors such as

./arch/alpha/include/uapi/asm/mman.h:53:0: error: "MADV_FREE" redefined
./arch/alpha/include/uapi/asm/mman.h:50:0: note:
this is the location of the previous definition

for the affected architectures.

Fixes: 21f55b018ba5 ("arch/*/include/uapi/asm/mman.h: : let MADV_FREE have same value for all architectures")
Fixes: ef58978f1eaa ("mm: define MADV_FREE for some arches")
