kernel 2.6.11.11 and x86_64 arch

[Vanuxem Grégory <g.vanuxem@wanadoo.fr>]

Hi,

For information, here are some change on
the last stable kernel. A lot of work on
x86_64.



Cheers,

    [PATCH] x86_64: Don't look up struct page pointer of physical
address in iounmap
    
    It could be in a memory hole not mapped in mem_map and that causes the hash
    lookup to go off to nirvana.
    

    [PATCH] x86_64: When checking vmalloc mappings don't use pte_page
    
    The PTEs can point to ioremap mappings too, and these are often outside
    mem_map.  The NUMA hash page lookup functions cannot handle out of bounds
    accesses properly.
    
    [PATCH] x86_64: Add a guard page at the end of the 47bit address space
    
    This works around a bug in the AMD K8 CPUs.
    

    [PATCH] x86_64: Fix canonical checking for segment registers in ptrace
    
    Allowed user programs to set a non canonical segment base, which would cause
    oopses in the kernel later.
    

    [PATCH] x86_64: check if ptrace RIP is canonical
    
    This works around an AMD Erratum.
