Juergen Gross 77089467fc platform/x86/dell: add buffer allocation/free functions for SMI calls ... The dcdbas driver is used to call SMI handlers for both, dcdbas and dell-smbios-smm. Both drivers allocate a buffer for communicating with the SMI handler. The physical buffer address is then passed to the called SMI handler via %ebx. Unfortunately this doesn't work when running in Xen dom0, as the physical address obtained via virt_to_phys() is only a guest physical address, and not a machine physical address as needed by SMI. The problem in dcdbas is easy to correct, as dcdbas is using dma_alloc_coherent() for allocating the buffer, and the machine physical address is available via the DMA address returned in the DMA handle. In order to avoid duplicating the buffer allocation code in dell-smbios-smm, add a generic buffer allocation function to dcdbas and use it for both drivers. This is especially fine regarding driver dependencies, as dell-smbios-smm is already calling dcdbas to generate the SMI request.
