Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ARM: rockchip: fix kernel hang during smp initialization<br /> <br /> In order to bring up secondary CPUs main CPU write trampoline<br /> code to SRAM. The trampoline code is written while secondary<br /> CPUs are powered on (at least that true for RK3188 CPU).<br /> Sometimes that leads to kernel hang. Probably because secondary<br /> CPU execute trampoline code while kernel doesn&amp;#39;t expect.<br /> <br /> The patch moves SRAM initialization step to the point where all<br /> secondary CPUs are powered down.<br /> <br /> That fixes rarely hangs on RK3188:<br /> [ 0.091568] CPU0: thread -1, cpu 0, socket 0, mpidr 80000000<br /> [ 0.091996] rockchip_smp_prepare_cpus: ncores 4
