[PATCH 0/5] x86,vdso: Restore a bunch of section headers

From: Andy Lutomirski
Date: Wed Jun 18 2014 - 19:01:42 EST


This series makes me sad. It brings the 64-bit vdso back above 4kB,
like it was in 3.15. It's also just silly, but it seems to be
needed to keep binutils happy when debugging the vdso.

Patch 5 isn't really necessary, and is likely not 3.16 material.
It's useful for testing the rest of this series, though.

Andy Lutomirski (5):
x86,vdso: Discard the __bug_table section
x86,vdso2c: Use better macros for ELF bitness
x86,vdso: Improve the fake section headers
x86,vdso: Remove some redundant in-memory section headers
x86,vdso: Create .build-id links for unstripped vdso files
