[PATCH v2 0/5] x86,vdso: Restore a bunch of section headers

[Andy Lutomirski]

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.

Only patch 5 changed from v1:
 - Fix for old binutils.
 - Pass --build-id, since normal binutils may not have it on by default.

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
