This should allow the printk buffer to be sized during config.
The default size is still 16K. It could use some checking to
insure power-of-2, but CML1 doesn't have a way to
do it that I see. All the architectures should be
covered, and all the default files also have it.

It gets added in the kernel hacking section.

Having 8 software raid volumes most of the kernel hardware
detection messages get lost. Having to edit kernel/printk.c
before/after every kernel change is a mess and easy to forget.

I'm gouing to work on a resizing buffer, that drops to 4K or
8K after dmesg is called with the right switch.

Patch against 2.4.3-ac2 since it has more arch supported.

The embedded systems like arm, might want to change
the default size to something smaller for their arch,
whiuch is easier with this patch.

+Printk buffer size
+CONFIG_PRINTK_BUF_LEN
+  Printk buffer size in K bytes. This should be a power of 2.
+  The 2.2.x kernels used a default of 8. The 2.4.x kernels
+  use a default of 16. Systems with many Software-RAID volumes
+  should increase since the md.o drivers have a lot of printk
+  output during boot.
