[Bug 1915027] [NEW] RISC-V 64, CPUs do ilegal 0x00 write with SMP

Subject: [Bug 1915027] [NEW] RISC-V 64, CPUs do ilegal 0x00 write with SMP
Date: Mon, 08 Feb 2021 15:09:00 -0000

Public bug reported:

When QEMU is runt like this:

qemu-system-riscv64 -d unimp,guest_errors -smp 8

Other harts will do a illegal write on address 0x00.

This could be mostly (i think) because the initial assembly code is only
loaded on the first hart and the others do a mess because there is no
code to execute.
