  • 07cdb7843   [MIPS] fix sparse warning about setup_early_printk() ... Browse Code »

    This patch fixes the following sparse warning:

    <<<<<<<<

    arch/mips/kernel/early_printk.c:35:13: warning: symbol 'setup_early_printk'
    was not declared. Should it be static?

    <<<<<<<<

    The fix is to define a prototype of the setup_early_printk() function and
    to include the appropriate header into arch/mips/kernel/early_printk.c.

    [Ralf: Sorted includes again]

  • 69331af79   Fixes and cleanups for earlyprintk aka boot console ... Browse Code »

    The console subsystem already has an idea of a boot console, using the
    CON_BOOT flag. The implementation has some flaws though. The major
    problem is that presence of a boot console makes register_console() ignore
    any other console devices (unless explicitly specified on the kernel
    command line).

    This patch fixes the console selection code to *not* consider a boot
    console a full-featured one, so the first non-boot console registering will
    become the default console instead. This way the unregister call for the
    boot console in the register_console() function actually triggers and the
    handover from the boot console to the real console device works smoothly.
    Added a printk for the handover, so you know which console device the
    output goes to when the boot console stops printing messages.

    The disable_early_printk() call is obsolete with that patch, explicitly
    disabling the early console isn't needed any more as it works automagically
    with that patch.

    I've walked through the tree, dropped all disable_early_printk() instances
    found below arch/ and tagged the consoles with CON_BOOT if needed. The
    code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf).

    Changes to last version: Rediffed against -rc3, adapted to mips cleanups by
    Ralf, fixed "udbg-immortal" cmd line arg on powerpc.
