+m68k: enabled software emulation of separate supervisor/user stack
|
|
|
+
|
|
|
+Recent Coldfires have separate supervisor and user stack pointers, but
|
|
|
+since older Coldfires didn't have that, the Linux kernel has a kind of
|
|
|
+emulation mechanism for those pointers.
|
|
|
+
|
|
|
+Apparently, according to the Kconfig.cpu file, the 5208 is supposed to
|
|
|
+support such separate pointers, but Qemu doesn't implement it. So we
|
|
|
+cheat a bit here and force the usage of emulated separate stack
|
|
|
+pointers.
