-Subject: [PATCH] MIPS: Switch to the irq_stack in interrupts
-
-When enterring interrupt context via handle_int or except_vec_vi, switch
-to the irq_stack of the current CPU if it is not already in use.
-
-The current stack pointer is masked with the thread size and compared to
-the base or the irq stack. If it does not match then the stack pointer
-is set to the top of that stack, otherwise this is a nested irq being
-handled on the irq stack so the stack pointer should be left as it was.
-
-The in-use stack pointer is placed in the callee saved register s1. It
-will be saved to the stack when plat_irq_dispatch is invoked and can be
-restored once control returns here.
