Subject: [IA64] get back PT_IA_64_UNWIND program header
X-Git-Tag: v2.6.23-rc4~124^2~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9bf77d0e20d08f4fd5f3b14e50dce3bb21df03ac;p=linux-2.6

[IA64] get back PT_IA_64_UNWIND program header

Explicitly put the unwind section into its own program-header.  This
used to be unnecessary (probably because binutils did it for us), but
with current binutils (e.g., v2.17.50.20070804) we won't get
the PT_IA_64_UNWIND header without this patch which will break
unwinding in a debugger and simulators such as Ski.
