printk.c: use unsigned ints instead of longs for logbuf index

2008-02-06T18:41:04+00:00

Stop using unsigned _longs_ for printk buffer indexes.  Log buffer is way
smaller than 2 gigabytes and unsigned ints will work too .  Indeed, they do
work nicely on all 32-bit platforms where longs and ints are the same.

With this patch, we have following size savings on amd64:

   text    data     bss     dec     hex filename
   5997     313   17736   24046    5dee 2.6.23.1.t64/kernel/printk.o
   5858     313   17700   23871    5d3f 2.6.23.1.printk.t64/kernel/printk.o

debug: turn ignore_loglevel into an early param

2008-01-31T21:45:23+00:00

i was debugging early crashes and wondered where all the printks
went. The reason: ignore_loglevel_setup() was not called yet ...

x86: make early printk selectable on 64-bit as well

2008-01-30T12:33:06+00:00

Enable CONFIG_EMBEDDED to select CONFIG_EARLY_PRINTK on 64-bit as well.

saves ~2K:

printk: use ktime_get()

2008-01-25T20:08:34+00:00

printk timestamps: use ktime_get().

Some platforms have a functioning clocksource function only after
they are done with early bootup, so delay this until out of
SYSTEM_BOOTING state.

it's also inherently safe now, as any bugs in this area will be
caught by the printk recursion checks.

sched: fix CONFIG_PRINT_TIME's reliance on sched_clock()

Stefano Brivio reported weird printk timestamp behavior during
CPU frequency changes:

  http://bugzilla.kernel.org/show_bug.cgi?id=9475

fix CONFIG_PRINT_TIME's reliance on sched_clock() and use cpu_clock()
instead.
