e100ae92a6 [TIPC]: Disallow config operations that aren't supported in certain modes.
This change provides user-friendly feedback when TIPC is unable to perform
certain configuration operations that don't work properly in certain modes.
(In particular, any reconfiguration request that would temporarily take TIPC
from network mode to standalone mode, or from standalone mode to not running
mode, is disallowed.)

3ac90216ab [TIPC] Fix for NULL pointer dereference
This fixes a bug spotted by the coverity checker, bug id #366. If
(mod(seqno - prev) != 1) we set buf to NULL, dereference it in the for
case, and set it to whatever value happes to be at adress 0+next, if it
happens to be non-zero, we even stay in the loop. It seems that the author
intended to break there.

260082471e [TIPC]: Links now validate destination node specified by incoming messages.
This fix prevents link flopping and name table inconsistency problems arising
when a node is assigned a different <Z.C.N> value than it used previously.
(Changing the <Z.C.N> value causes other nodes to have two link endpoints
sending to the same MAC address using two different destination <Z.C.N> values,
requiring the receiving node to filter out the unwanted messages.)

fcc18e83e1 [PATCH] uclinux: use PER_LINUX_32BIT in binfmt_flat
binfmt_flat.c calls set_personality with PER_LINUX as the personality.
On the arm architecture this results in the program running in 26bit
usermode.  PER_LINUX_32BIT should be used instead.  This doesn't affect
other architectures that use binfmt_flat.

623f523cc0 [PATCH] m68knommu: improve syscall entry and fix strace
Here is a patch to the system call handling for 5307/5272/etc to:

- fix the strace support (one tested the wrong bit)
- make all system calls a little bit faster by inlining set_esp0 and
  supporting ENOSYS out of the critical path.
- remove extraneous spaces

7bf9a37d8d [PATCH] m68knommu: force stack alignment on ColdFire
This patch solve a bug triggered by execvp (this function use calloc to
store the argument list and gcc 3.4.x align the stack to word, not to dword).
This situation aren't related to signal handling and all 2.6.x have the bug.
On ColdFire targets we must force the stack to be aligned.
