    Subject[PATCH v3 0/3] vmalloc kernel mapping and relocatable kernel
    Date
    This patchset originally implemented relocatable kernel support but now
    also moves the kernel mapping into the vmalloc zone.

    The first patch explains why we need to move the kernel into vmalloc
    zone (instead of memcpying it around). That patch should ease KASLR
    implementation a lot.

    The second patch allows to build relocatable kernels but is not selected
    by default.

    The third patch takes advantage of an already existing powerpc script
    that checks relocations at compile-time, and uses it for riscv.

    Alexandre Ghiti (3):
    riscv: Move kernel mapping to vmalloc zone
    riscv: Introduce CONFIG_RELOCATABLE
    arch, scripts: Add script to check relocations at compile time
