Hello,
During make bzImage, I received the following:

init/main.o: In function 'start_kernel' init/main.o(.text.init+0x842): undefined reference to 'pgtable_cache_init'
make: *** [vmlinux] Error 1

Regards,
Frank

Hello,

Which architecture are you building for?

I've seen this as well on i386. It crops up when you are using HIGHMEM. In include/asm-i386/pgtable.h you declare pgtable_cache_init if HIGHMEM is on, or define it to the empty while loop if not. It really needs to be calling init_pae_pgd_cache instead though. Try this patch against 2.4.9-ac4. I don't know if changing the name of init_pae_pgd_cache was the Right Thing (tm) to do, but it worked for me. It's not getting called anywhere else anyways.

It got changed because we don't want to add multiple architecture specific functions to init/main.c, but rather have one generic call which any architecture can use for this type of thing.
