printk/sched: Introduce special printk_sched() for those awkward moments

2012-03-12T19:43:16Z

There's a few awkward printk()s inside of scheduler guts that people prefer to keep but really are rather deadlock prone. Fudge around it by storing the text in a per-cpu buffer and poll it using the existing printk_tick() handler. This will drop output when its more frequent than once a tick, however only the affinity thing could possible go that fast and for that just one should suffice to notify the admin he's done something silly..

dynamic_debug: make dynamic-debug supersede DEBUG ccflag

2012-01-24T20:46:44Z

If CONFIG_DYNAMIC_DEBUG is defined, honor it over DEBUG, so that pr_debug()s are controllable, instead of always-on. When DEBUG is also defined, change _DPRINTK_FLAGS_DEFAULT to enable printing by default. Also adding _DPRINTK_FLAGS_INCL_MODNAME would be nice, but there are numerous cases of pr_debug(NAME ": ...), which would result in double printing of module-name. So defer this until things settle.

printk: allocate kernel log buffer earlier

2011-05-25T15:39:48Z

On larger systems, because of the numerous ACPI, Bootmem and EFI messages, the static log buffer overflows before the larger one specified by the log_buf_len param is allocated. Minimize the overflow by allocating the new log buffer as soon as possible. On kernels without memblock, a later call to setup_log_buf from kernel/init.c is the fallback.
