I noticed that several global buffers are used by a few functions marked as __init functions. I assume that the code space used by these functions will be freed up when kernel initialization is completed, but can the associated global memory be freed up as well? An example can be found in arch/mips/mips-boards/generic/cmdline.c: char arcs_cmdline[COMMAND_LINE_SIZE]; char * __init prom_getcmdline(void); void __init prom_init_cmdline(void); arcs_cmdline is only used by these two functions and one other function marked as __init. This buffer is small, but it can apply to larger buffers as well. For example, in arch/mips/mips-boards/generic/printf.c, I think the functions putPromChar and getPromChar should be marked as __init functions, and the 1k buffer "buf" is never used after initialization. Can this 1k be recovered? I know kmalloc could normally be used in kernel code, but that won't work on initialization code used before kmalloc is initialized. Thanks. Gerald
