Changelog extract

* Correct error path in rmmod.c. Andrew Morton.
* Include latest Redhat alias list. Bill Nottingham.
* hppa and hppa64 support. Richard Hirst.
* Rework Makefiles for common 32/64 code. Keith Owens.
* Add parportmap. Adam J Richter, Keith Owens.
* Use GNU standards for cross compile. Maciej W. Rozycki.
* Fix bound check on generic_string. Bug reported by Jaroslav Kysela, different patch by Keith Owens.
* Warn instead of error for invalid MODULE_PARM. Keith Owens.

Notes:

(1) Persistent data is not on by default, you must run insmod with -e to support persistent data. If you are loading modules via modprobe and you want persistent data for all modules then you need

insmod_opt -e ""

in /etc/modules.conf.

(2) Current kernels do not support persistent data nor generic strings. You must apply patch-2.4.0-test13-pre2 to get kernel support for these features.

(3) No modules currently have persistent data. Module writers who want data to be persistent must make a one character change to their modules, read the above patch. Even then, the user must activate the persistent data, see note (1).

About Standard aliases:

...
alias ppp-compress-21 bsd_comp
...

Why bsd_comp is the standard alias?
/src/linux/Configure.help says that

The PPP Deflate compression method ("PPP Deflate compression",
above) is preferable to BSD-Compress, because it compresses better and is patent-free.

You should also have
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate

The number is the CPP option that was requested by pppd, which compression option is used is controlled by userspaqce, not the kernel.

ppp-compress-21 refers to PPP compression method 21, which happens to be BSD Compress. Deflate is 26 (and also 24, because it was assigned that
value in the draft RFC).

Aliasing ppp-compress-21 to anything other than bsd_comp would break PPP.
