Hi all,
Why does this doc: https://www.kernel.org/doc/Documentation/x86/x86_64/mm.txt
not contain entries for the IRQ and SOFTIRQ stack? Are those stacks dynamically allocated in one of the areas in this table? Or is the doc just outdated? Would it be valuable to update it?
I'm not sure that document would be the best place to document the separate IRQ and NMI stacks. It may make sense to create a separate document about the entry and exit code, which also documents the different stacks. At least, I suspect the stacks make most sense when the mechanism that jumps around between them is documented in the same place. I may be wrong, of course :) -- All Rights Reversed.
