    [PATCH] x86_64 merge: arch + asm · 0457d99a
    Andi Kleen authored
    This adds the x86_64 arch and asm directories and a Documentation/x86_64.
    
    It took a bit longer because I first had to make preemption and thread_info
    work and also found some other bugs while doing this. The port has been
    tested for a long time on UP.
    
    I'm not sure what I should describe.  A lot is based on i386 with
    a lot of cleanups. I wrote a paper about it for last year's OLS that describes
    most of the changes (ftp://ftp.firstfloor.org/pub/ak/x86_64.ps.gz). It is
    a bit outdated now, but should give a good overview.
    
    It currently has a completely cut'n'pasted from others+hacked 32bit
    emulation. I hope to clean that up in the future by merging the generic
    core of this with other 64bit archs.
    
    Thanks,
    -Andi
