Commit d3ce88431892b703b04769566338a89eda6b0477 (MIPS: Fix modpost
error in modules attepting to use virt_addr_valid()) in 3.8-rc3 broke
the 64-bit MIPS build:
LD init/built-in.o
kernel/built-in.o: In function `memory_bm_free':
snapshot.c:(.text+0x3c76c): undefined reference to `__virt_addr_valid'
snapshot.c:(.text+0x3c800): undefined reference to `__virt_addr_valid'
kernel/built-in.o: In function `snapshot_write_next':
(.text+0x3e094): undefined reference to `__virt_addr_valid'
kernel/built-in.o: In function `snapshot_write_next':
(.text+0x3e468): undefined reference to `__virt_addr_valid'
Fix by providing __virt_addr_valid also when CONFIG_32BIT is not set.
