uml-stop-saving-process-fp-state.patch broke the UML/x86_64 build.
On x86_64, sys/ptrace.h has to be included before asm/ptrace.h.

Otherwise, the defines in asm/ptrace.h will ruin the parse of

sys/ptrace.h -

    asm/ptrace.h:

	#define PTRACE_GETREGS            12
    sys/ptrace.h:

	enum __ptrace_request

	{

	...

	   PTRACE_GETREGS = 12,

	...

	}
Also, errno.h was missing.
