[PATCH v1 4/4] ACPI: OSL: Use GFP_KERNEL for work item allocations

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

After the recent modification changing the ACPI SCI interrupt handler
into a threaded one, the SCI interrupt handler code does not run in
interrupt context any more and acpi_os_execute(), that may be invoked
by it, need not use GFP_ATOMIC for allocating work items.

Make it use GFP_KERNEL instead.
