Hi-

I began by wanting to see "mem=exactmap" listed in
Documentation/kernel-parameters.txt, and then it just
grew from there.

Change summary:
 kernel-parameters.txt |   32 ++++++++++++++++++++++++--------
 1 files changed, 24 insertions(+), 8 deletions(-)

. add IP_PNP kernel parameter category (was just "PNP")

. change occurrences of "ix86" to "IA-32" (not that I care,
  but the file says that IA-32 is for i386 family stuff)

. [ARM only] change "keep_initrd" to "keepinitrd" as used in
  source code

. add some missing kernel parameters

. add "mem=exactmap"

Patch is against 2.4.19, but 2.4.20-pre7 and same-ac don't
contain any changes to Documentation/kernel-parameters.txt.

Comments or corrections before I ask Marcelo to apply it?

Thanks,
~Randy
