Switching some ICU interrupts to +the second VPE results in a hang. Currently, the vsmp_init_secondary() +function is responsible for enabling these interrupts.

Each VPE has an independent +instance of the ICU. The mapping of the ICU interrupts is shown below: +SW0(IP0) - IPI call, +SW1(IP1) - IPI resched, +HW0(IP2) - ICU 0-31, +HW1(IP3) - ICU 32-63, +HW2(IP4) - ICU 64-95, +HW3(IP5) - ICU 96-127, +HW4(IP6) - ICU 128-159, +HW5(IP7) - timer. + +This patch enables all interrupt lines on the second VPE. + +This problem affects multithreaded SoCs with a custom interrupt controller. +SOCs with 1004Kc core and newer use the MIPS GIC.
