Message:

Attempt to fix ALSA on Linux kernels <= 2.6.17: use mmap not memalign for allocating pages. Use madvise or mprotect to separater VM area structs inside the kernel. Most SUP* functions work on cPages now (not cBytes anymore). The free functions take a cPages parameter which is used for munmap on Linux.
