Hi,
I get the following UML compile error on linux-next-20080521 , 64bit box :
...
CC arch/um/sys-x86_64/ksyms.o
arch/um/sys-x86_64/ksyms.c:5: error: '__memcpy' undeclared here (not in a function)
arch/um/sys-x86_64/ksyms.c:5: warning: type defaults to 'int' in declaration of '__memcpy'
make[1]: *** [arch/um/sys-x86_64/ksyms.o] Error 1
make: *** [arch/um/sys-x86_64] Error 2
...
config is UM's defconfig.
Regards,
Gabriel

Does the patch below help? There's gcc-version-dependent logic in
include/asm-x86/string_64.h which decides whether to declare memcpy or
__memcpy and it looks like you're hitting that.

Yes is fixes this error , however I get now another one but this one seems to be an compiler bug.
...

...
This is gcc 4.3.0 ( with backports of some known fixed bugs ).
I try to build latest snapshot of gcc 4.3* later on today and try with this one.
