Damn.. Posted a wrong version of the patch ;-(
Here is the one with warning message included.

Subject: [PATCH] mm: nobootmem: avoid type warning about alignment value

Building ARM with NO_BOOTMEM generates below warning.

mm/nobootmem.c: In function ?__free_pages_memory?:
mm/nobootmem.c:88:11: warning: comparison of distinct pointer types lacks a cast

Using min_t to find the correct alignment avoids the warning.
