| |
2.6.34-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gabor Gombas <gombasg@digikabel.hu>
commit 3d6e77a3ddb8e4156b89f4273ff8c7d37abaf781 upstream.
The low-memory corruption checker triggers during suspend/resume, so we need to reserve the low 64k. Don't be fooled that the BIOS identifies itself as "Dell Inc.", it's still Phoenix BIOS.
[ hpa: I think we blacklist almost every BIOS in existence. We should either change this to a whitelist or just make it unconditional. ]
