Documentation: kernel-parameters.txt cleanups
General cleanups to kernel-parameters.txt: - add missing $ARCH that are being used/referenced - alphabetize the parameter restrictions list - spell "IA-64" as listed in arch/ia64/Kconfig instead of "IA64" - remove trailing whitespace - use hyphen in 32-bit etc. Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
