Subject: Problem with kernel 2.6.15's build target .tmp_vmlinux1

Greetings,

I've run into a problem building 2.6.15. Starting with my 2.6.14
.config file, I ran oldconfig to generate a .config for 2.6.15.
Running "make" results in:

LD .tmp_vmlinux1
kernel/built-in.o: In function `do_exit':
: undefined reference to `exit_io_context'
mm/built-in.o: In function `generic_write_checks':
: undefined reference to `bdev_read_only'
mm/built-in.o: In function `__generic_file_aio_write_nolock':
: undefined reference to `bdev_read_only'
mm/built-in.o: In function `__alloc_pages':
: undefined reference to `blk_congestion_wait'
mm/built-in.o: In function `__alloc_pages':
: undefined reference to `blk_congestion_wait'

Makefile indicates that KALLSYMS is involved in building this target,
so here are two combinations of KALLSYMS settings that result in the
same problem:

CONFIG_KALLSYMS=y
# CONFIG_KALLSYMS is not set
# CONFIG_KALLSYMS is not set

CONFIG_KALLSYMS=y
# CONFIG_KALLSYMS_ALL is not set
CONFIG_KALLSYMS_EXTRA_PASS=y

Makefile mentions that the maintainers are working on problems with
kallsyms, which is why I'm reporting this problem.

If you need any more info (such as a copy of .config), let me know.

Regards,

David
