Subject[PATCH] extend the limits for command line
Hello!

(I resend this because I get no feedback.)

Testing UML on my project, I hit the limit for command line with something like
this:

default \
mem=64M \
ubda=COW,/data/UML4/roots/ROOT1 \
ubdb=SWAP \
ubdc=CONF.tar \
${HSSTR} \
eth0=daemon,fe:fd:39:bd:cc:d7,,/data/UML4/conf/example1/socks/SW1
eth1=daemon,fe:fd:01:01:01:12,,/data/UML4/conf/example1/socks/SW2
eth2=daemon,fe:fd:01:01:01:99,,/data/UML4/conf/example1/socks/SW4
eth3=daemon,fe:fd:01:01:01:03,,/data/UML4/conf/example1/socks/SW5
eth4=daemon,fe:fd:01:01:01:04,,/data/UML4/conf/example1/socks/SW6
eth5=daemon,fe:fd:01:01:01:81,,/data/UML4/conf/example1/socks/SW8p1
eth6=daemon,fe:fd:3f:a9:35:e2,,/data/UML4/conf/EXTERN/E1 \
con=null \
ssl0=port:9101 \
umid=example1-pc1 \
@pc1@


Patch to extend the limits (buffer and number of args/envs) is attached.
Please consider including it because UML is intended to be run with such
long lines.
I'm open to other alternatives as a Kconfig entry for this.

Thank you!
