Hi Matt, Thanks for submitting this. A happy OpenWRT/WireGuard user has reported to me that this patch set frees ~1300 bytes of stack on a small MIPS router. This kind of savings should allow me to reintroduce my crypto operations to be on the stack, rather than the conditional MIPS kmallocing, wh

2016-12-02 Thread Matt Redfearn
This series adds a separate stack for each CPU wihin the system to use when handling IRQs. Previously IRQs were handled on the kernel stack of the current task. If that task was deep down a call stack at the point of the interrupt, and handling the interrupt required a deep IRQ stack, then there w
