  "title": "ARM: rockchip: fix kernel hang during smp initialization",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  ARM: rockchip: fix kernel hang during smp initialization  In order to bring up secondary CPUs main CPU write trampoline code to SRAM. The trampoline code is written while secondary CPUs are powered on (at least that true for RK3188 CPU). Sometimes that leads to kernel hang. Probably because secondary CPU execute trampoline code while kernel doesn\u0027t expect.  The patch moves SRAM initialization step to the point where all secondary CPUs are powered down.  That fixes rarely hangs on RK3188: [    0.091568] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000 [    0.091996] rockchip_smp_prepare_cpus: ncores 4",
