x86, setup: Phoenix BIOS fixup is needed on Dell Inspiron Mini 1012
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. ] Signed-off-by: Gabor Gombas <gombasg@digikabel.hu> LKML-Reference: <201005241913.o4OJDIMM010877@imap1.linux-foundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: H.
