OK, I guess I gave too much credit :)
This gives 4 options, 4K, 8K, 16K, and 32K.
4K is for the embedded guys, but they might want even less.
32K is enought for 9 RAID1 and RAID0 volumes.
64K seams like overkill too me. But if anyone wants/needs it,
I'll add it in. Same for smaller buffers.
Now to work on using a boot param, and reducing after
booting with dmesg. That'll take me a while I'm sure.

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.

IMO, it would be nice to add a test here whether the CONFIG_PRINTK_BUF_LEN
value is really set as a power of two, eg.:
#if (LOG_BUF_LEN & LOG_BUF_MASK)
#error CONFIG_PRINTK_BUF_LEN must be a power of two
#endif
(above works with egcs-2.91.66)

I couldn't figure out how to do it in the config,
forgot about preprocessing. But Alan wants a menu
option instead.
Anyone who uses the embedded systems want
a different default? Let me know and I'll
put it in the default config files.
I'm sure a small hand held with fixed devices
doesn't need even a 8K buffer. Just don't know
which ones.
