[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.
