crypto/nx/nx-842: Fix handling of vmalloc addresses The powerpc specific nx-842 compression driver does not currently handle translating a vmalloc address to a physical address. The current driver uses __pa() for all addresses which does not properly handle vmalloc addresses and thus causes a failure since we do not pass a proper physical address to the hypervisor. This patch adds a routine to convert an address to a physical address by checking for vmalloc addresses and handling them properly.
