[IA64] Tighten up unw_unwind_to_user check
Detect user space by the unwind frame with predicate PRED_USER_STACK
set, instead of a user space IP. Tighten up the last ditch check for
running off the top of the kernel stack.
Based on a suggestion by David Mosberger, reworked to fit the current
tree. This survives my stress test which used to break 2.6.9 kernels.
Unlike 2.6.11, the stress test now unwinds to the correct point, so
gdb can get the user space registers.

[PATCH] ia64: force all kernel sections into one and the same segment
Older versions of the linker do not handle cross-segment segment-relative
relocations properly. This becomes a real problem when the linker decides
to put .text and .text.init into different segments (for whatever reasons)
because in that case, broken linkers will produce a broken unwind section,
which can cause nasty Heisenbugs, where, for example, unwinding may or may
not work depending on the exact value of the IP in a function.
[Backport of Keith Owens' 2.6 change]
Thanks!
Bjorn
