Cover letter [0/3] i386 stack handling updates
This is a series of patches to improve i386 stack handling in several manners. The net result is to improve system stability via IRQ stacks while remaining memory efficient and to improve stack debugging.
[1/3] dynamically allocate irq stacks
This conserves memory while using IRQ stacks.
[2/3] make irqstacks unconditional, while retaining 4/8k stack selection
This makes IRQ stacks the standard for mainline.
[3/3] DEBUG_STACK option enabling vmalloc()'ed stacks and __pa checks
Stack debugging option using vmalloc() to establish guard pages.
