Dave Jones a64882e795 [PATCH] ACPI: fix sleeping whilst atomic warnings on resume 
This has been broken for months.  On resume, we call acpi_pci_link_set()
with interrupts off, so we get a warning when we try to do a kmalloc of non
atomic memory.  The actual allocation is just 2 long's (plus extra byte for
some reason I can't fathom), so a simple conversion to GFP_ATOMIC is
probably the safest way to fix this.

The error looks like this..

Debug: sleeping function called from invalid context at mm/slab.c:2486
in_atomic():0, irqs_disabled():1
