careful with line 80 warnings. This one is better broken up the
following way:

printk(" [<%016lx>] %s%pS\n",
address, reliable ? "": "? ", (void *) address);

so that logically coherent pieces of code stay together. (the arguments
to the printk() function call in this case)

this too is done better in another way:

[N_EXCEPTION_STACKS ...
N_EXCEPTION_STACKS + DEBUG_STKSZ / EXCEPTION_STKSZ - 2] = "#DB[?]"

please use the standard multi-line comment format:

/*

i've applied your patches already to x86/cleanups, so please send a
delta patch against that branch to fix these few items up. You can pick
it up via:

http://people.redhat.com/mingo/tip.git/README

and do:

git-checkout tip/x86/cleanups

to check out that exact tree. (You might also want to work against
tip/master, which has the same changes.)
