I see this:
CPU0
7: 104068 INTC TWL4030-PIH
12: 4 INTC DMA
37: 1408 INTC gp timer
56: 313486 INTC i2c_omap
61: 0 INTC i2c_omap
74: 42 INTC serial
77: 93 INTC ehci_hcd:usb2
83: 66 INTC mmc0
86: 12 INTC mmc1
92: 1 INTC musb_hdrc
336: 809 GPIO eth0
378: 0 twl4030 twl4030_usb
384: 0 twl4030 mmc0
I believe the interrupts tagged "twl4030" are chained interrupts. Having
looked at the code, these interrupts are not chained the usual way
because they require i2c communication, which in turn requires a context
allowed to sleep, so they are dispatched by a kernel thread.
