Only x86 and x86_64 use arch_align_stack(), all other subarches have:
#define arch_align_stack(x) (x)
So, if this definition is found, UML's own arch_align_stack() should be
skipped.

s390 needs to change some parts of arch/um/kernel/ptrace.c. Thus, the code
regarding PEEKUSER and POKEUSER are shifted to arch/um/sys-<subarch>/ptrace.c.
Also s390 debug registers need to be updated, when singlestepping is switched
on / off. Thus, setting/resetting of singlestepping is centralized in the new
function set_singlestep(), which also inserts the macro
SUBARCH_SET_SINGLESTEP(mode), if defined.
Finally, s390 has the "ieee_instruction_pointer" in its
registers, which also is allowed to be read via
ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0);
To implement this feature, sys_ptrace inserts the macro
SUBARCH_PTRACE_SPECIAL, if defined.

This change from March 3rd causes the partition parsing code to ignore
partitions which have a signature byte of zero. Turns out that more people
have such partitions than we expected, and their device numbering is coming up
wrong in post-2.6.11 kernels.

There's a slight bug in the routines in that if the period requires dt,
then the routine will unconditionally set it. DT may only be set if
Wide is also set, so this turns back on the wide bit.
For domain validation to work correctly, we need to observe the wide bit
absolutely.

on ppc64, we made the decision of enforcing the presence of an

The code in unflatten_device_tree knows that get_property is written to
only return with lenp equal to 1 when also returning a valid pointer.
The gcc 3.3.3 compiler is not able to prove this to itself, so it warns
about a possible uninitialized pointer dereference:
.../arch/ppc64/kernel/prom.c: In function `unflatten_device_tree':
.../arch/ppc64/kernel/prom.c:828:
warning: `p' might be used uninitialized in this function
