[PATCH] uml: small fixes left over from rc4

Browse Source 
Some changes that I sent in didn't make 2.6.12-rc4 for some reason.  This
adds them back.  We have
	an x86_64 definition of TOP_ADDR
	a reimplementation of the x86_64 csum_partial_copy_from_user
	some syntax fixes in arch/um/kernel/ptrace.c
	removal of a CFLAGS definition in the x86_64 Makefile
	some include changes in the x86_64 ptrace.c and user-offsets.h
	a syntax fix in elf-x86_64.h
Also moved an include in the i386 and x86_64 Makefiles to make the symlinks
work, and some small fixes from Al Viro.
