    parisc: Initialize the fault vector earlier in the boot process. · 4182d0cd
    Helge Deller authored
    A fault vector on parisc needs to be 2K aligned.  Furthermore the
    checksum of the fault vector needs to sum up to 0 which is being
    calculated and written at runtime.
    
    Up to now we aligned both PA20 and PA11 fault vectors on the same 4K
    page in order to easily write the checksum after having mapped the
    kernel read-only (by mapping this page only as read-write).
    But when we want to map the kernel text and data on huge pages this
    makes things harder.
    So, simplify it by aligning both fault vectors on 2K boundries and write
    the checksum before we map the page read-only.
