Hi,
Today I try to make MIPS kernel, and get this error:
cc -c -O2 -pipe -fno-strict-aliasing -march=mips32 -std=c99 -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes
-Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -nostdinc -I.

Where is vm_contig_grow_cache(3, 0, MIPS_KSEG0_LARGEST_PHYS) defined?
I found vm_contig_grow_cache in sys/vm/vm_contig.c, but they wont only one argument.
