    x86: optimize page faults like all other achitectures and kill notifier cruft · 74a0b576
    Christoph Hellwig authored
    x86(-64) are the last architectures still using the page fault notifier
    cruft for the kprobes page fault hook.  This patch converts them to the
    proper direct calls, and removes the now unused pagefault notifier bits
    aswell as the cruft in kprobes.c that was related to this mess.
    
    I know Andi didn't really like this, but all other architecture maintainers
    agreed the direct calls are much better and besides the obvious cruft
    removal a common way of dealing with kprobes across architectures is
    important aswell.
