Linux Assembler: which registers to preserve?

When calling an assembler routine from within a Win32
context, it is clear that the values of EAX, ECX, and EDX
don't have to be preserved (while e.g. EBX, EBP, and ...
have to be preserved).

Can anyone enlighten me, which registers have to be preserved
when calling an assembler routine from within a Linux context?

(context = c or c++ program)
