[PATCH] ia64/Kconfig

[PATCH] ia64/Kconfig

[Bjorn Helgaas]

This Kconfig patch basically just makes ia64 look a little more like i386:
	- moves system type above processor type
	- moves PM & ACPI to a new top-level menu
	- moves PCI/PCMCIA to a new top-level menu

Anyone still running itanium processor nowadays? :-)

Yeah baby!  In fact, I'm writing this mail on a Bug^WBig Sur box right
now.  :)  A dual 733 MHz Merced isn't half bad as a desktop, though
it's a bit loud.

Indeed, the Merced came with either 2MB or 4MB caches ... implying that
on some carefully chosen workloads it just might outperform a McKinley ;-)

I really doubt it though.
