The patch titled
x86_64: Pass -32 to the assembler when compiling the 32bit vsyscall pages
has been added to the -mm tree. Its filename is
x86_64-pass-32-to-the-assembler-when-compiling.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: "Andi Kleen" <ak@xxxxxxx>
This quietens warnings and actually fixes a bug. The unwind tables would
come out wrong without -32, causing pthread cancellation during them to
crash in the gcc runtime.
The problem seems to only happen with newer binutils (it doesn't happen
with 2.16.91.0.2 but happens wit 2.16.91.0.5)
Thanks to Brian Baker @ HP for test case and initial analysis.
