Alexandre Ghiti e5c35fa040 riscv: Map the kernel with correct permissions the first time ... For 64-bit kernels, we map all the kernel with write and execute permissions and afterwards remove writability from text and executability from data. For 32-bit kernels, the kernel mapping resides in the linear mapping, so we map all the linear mapping as writable and executable and afterwards we remove those properties for unused memory and kernel mapping as described above. Change this behavior to directly map the kernel with correct permissions and avoid going through the whole mapping to fix the permissions. At the same time, this fixes an issue introduced by commit 2bfc6cd81b ("riscv: Move kernel mapping outside of linear mapping") as reported here https://github.com/starfive-tech/linux/issues/17.
