printk: robustify printk

2009-11-10T00:52:43+00:00

commit b845b517b5e3706a3729f6ea83b88ab85f0725b0 upstream.

Avoid deadlocks against rq->lock and xtime_lock by deferring the klogd
wakeup by polling from the timer tick.

introduce lower_32_bits() macro

2008-07-30T16:41:46+00:00

The file kernel.h contains the upper_32_bits macro.  This patch adds the
other part, the lower_32_bits macro.  Its first use will be in the driver
for AMD IOMMU.

printk ratelimiting rewrite

2008-07-25T17:53:29+00:00

All ratelimit user use same jiffies and burst params, so some messages
(callbacks) will be lost.

For example:
a call printk_ratelimit(5 * HZ, 1)
b call printk_ratelimit(5 * HZ, 1) before the 5*HZ timeout of a, then b will
will be supressed.

- rewrite __ratelimit, and use a ratelimit_state as parameter.  Thanks for
  hints from andrew.

- Add WARN_ON_RATELIMIT, update rcupreempt.h

- remove __printk_ratelimit

- use __ratelimit in net_ratelimit

Move _RET_IP_ and _THIS_IP_ to include/linux/kernel.h

2008-07-05T20:10:50+00:00

These two macros are useful beyond lock debugging. Moved definitions from
include/linux/debug_locks.h to include/linux/kernel.h, so code that needs
them does not have to include the former, which would have been a less
intuitive choice of a header.

x86, generic: mark early_printk as asmlinkage

2008-06-18T11:11:01+00:00

It's not explicitly marked as asmlinkage, but invoked from x86_32
startup code with parameters on stack.

No other architectures define early_printk and none of them are affected
by this change, since defines asmlinkage as empty token.

lib: create common ascii hex array

2008-05-15T02:11:14+00:00

Add a common hex array in hexdump.c so everyone can use it.

Add a common hi/lo helper to avoid the shifting masking that is
done to get the upper and lower nibbles of a byte value.

Pull the pack_hex_byte helper from kgdb as it is opencoded many
places in the tree that will be consolidated.
