Hi all,
I need the following two changes to get my favourite uml config
to compile (and run):
make ARCH=um SUBARCH=i386 KCONFIG_ALLCONFIG=mini.config allnoconfig
with mini.config:
CONFIG_BINFMT_ELF=y
CONFIG_BLK_DEV_INITRD=y
CONFIG_INITRAMFS_SOURCE="../initramfs"
CONFIG_EMBEDDED=y
CONFIG_KALLSYMS=y
CONFIG_PRINTK=y
CONFIG_BUG=y
CONFIG_SLOB=y
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
CONFIG_XTERM_CHAN=y
CONFIG_PROC_FS=y
CONFIG_SYSFS=y
Please review/comment (or create a better patch for this yourself!).
(If you need one:)

Yeah, this needs fixing, but I think we need a different fix.

Try the one below - it's a bit larger, but perhaps cleaner and more
future-proof.

Hi,
This approach is indeed a lot cleaner.
I need the following on top of this patch to get it to
compile for my configs. I have compiled for x86_64 for
SLOB/SLUB/SLAB. I have verified that the kernels run
fine for i386 for SLOB/SLUB/SLAB.

The only comment I have on the patch is that it introduces
spurious whitespace at the end of arch/um/include/um_malloc.h
