Hi Greg,

Picked up these MIPS IRQ stack patches from LEDE source tree,
for your consideration for stable 4.9.

Cherry-picked and build tested on v4.9.20 for
ARCH=mips + allmodconfig.

Felix Fietkau (1):
  MIPS: Lantiq: Fix cascaded IRQ setup

Matt Redfearn (6):
  MIPS: Introduce irq_stack
  MIPS: Stack unwinding while on IRQ stack
  MIPS: Only change $28 to thread_info if coming from user mode
  MIPS: Switch to the irq_stack in interrupts
  MIPS: Select HAVE_IRQ_EXIT_ON_IRQ_STACK
  MIPS: IRQ Stack: Fix erroneous jal to plat_irq_dispatch
