[uClinux-dev] [PATCH] m68k: make syscall_trace_enter/leave exist for non-MMU classic m68k types

[gerg]

From: Greg Ungerer <gerg at uclinux.org>

The assembler entry code calls directly to the syscall_trace_enter() and
syscall_trace_leave() functions. But currently they are conditionaly
compiled out for the non-MMU classic m68k CPU types (so 68328 for example),
resulting in a link error:

LD vmlinux
arch/m68k/platform/68328/built-in.o: In function `do_trace':
(.text+0x1c): undefined reference to `syscall_trace_enter'
arch/m68k/platform/68328/built-in.o: In function `do_trace':
(.text+0x4c): undefined reference to `syscall_trace_leave'

Change the conditional check that includes these functions to be true for
the !defined(CONFIG_MMU) case as well.

Hmm, should add syscall_trace support to M68KCLASSIC/MMU...

Gr{oetje,eeting}s,

That would be nice :-)
