Subject: [RFC] x86: Cleanup prose of Documentation/i386/IO-APIC.txt

I'm doing a couple of cleanups to Documentation/i386/IO-APIC.txt
and I have a problem with this line, which is supposed to compute
a sample pirq= kernel parameter:

   echo -n pirq=; echo `scanpci | grep T_L | cut -c56-` | sed 's/ /,/g'

The 'scanpci' command used to be part of xutils and/or XFree86.
Xorg implements "Xorg -scanpci" but the output is different and it won't
run while X is running.

Firstly I propose using the $( ) construct rather than backticks, since
it is easier to read:

   echo -n pirq=; echo $( scanpci | grep T_L | cut -c56- ) | sed 's/ /,/g'

Inside the backtics, instead of scanpci, I could do:

   lspci -v | grep IRQ | sed -e 's/.* IRQ \(\w\+\)/\1/'

Is this an acceptable substitution?

Nick.
