7873def499 m68k: Check syscall_trace_enter() return code
[ Upstream commit 2ca8a1de4437f21562e57f9ac123914747a8e7a1 ]

Check return code of syscall_trace_enter(), and skip syscall
if -1. Return code will be left at what had been set by
ptrace or seccomp (in regs->d0).

No regression seen in testing with strace on ARAnyM.

3ad3cbe305 m68k/coldfire: Use CONFIG_PREEMPTION
CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT.
Both PREEMPT and PREEMPT_RT require the same functionality which today
depends on CONFIG_PREEMPT.

Switch the entry code over to use CONFIG_PREEMPTION.

ece9ae6515 m68k: fix crufty ColdFire intro comments
Quite a few of the ColdFire specific support files have a pathname in the
title comments of the file. These files have moved around a bit over the
years, and most are no longer accurate. Remove the pathname and fix the
comments to include at least a short description of the files contents.

f86b9e0383 m68k: move coldfire platform code
Move the m68k ColdFire platform support code directory to be with the
existing m68k platforms. Although the ColdFire is not a platform as such,
we have always kept all its support together. No reason to change that
as this time.
