With all Linux ABIs using the expected Linux kABI to indicate syscalls errors, there is no need to replicate the INLINE_SYSCALL. The generic Linux sysdep.h includes errno.h even for !__ASSEMBLER__, which is ok now and it allows cleanup some archaic code that assume otherwise. Checked with a build against all affected ABIs.
