We consistently switched from kmalloc() to vmalloc() in module decompression to prevent potential memory allocation failures with large modules, however vmalloc() is not as memory-efficient and fast as kmalloc(). Since we don't know in general the size of the workspace required by the decompression algorithm, it is more reasonable to use kvmalloc() consistently, also considering that we don't have special memory requirements here.
