commit: ea17e7414bc62e8d3bde8d08e3df1d921c518c17 From: H. Peter Anvin <[email protected]> Date: Thu, 24 May 2012 07:01:38 -0700 Subject: x86, relocs: Add jiffies and jiffies_64 to the relative whitelist
The symbol jiffies is created in the linker script as an alias to jiffies_64. Unfortunately this is done outside any section, and apparently GNU ld 2.21 doesn't carry the section with it, so we end up with an absolute symbol and therefore a broken kernel. Add jiffies and jiffies_64 to the whitelist. The most disturbing bit with this discovery is that it shows that we have had multiple linker bugs in this area crossing multiple generations, and have been silently building bad kernels for some time.
