    [PATCH] Dynamic hugepage addresses for ppc64
    
    Paulus, I think this is now a reasonable candidate for the post-2.6.13
    queue.
    
    Relax address restrictions for hugepages on ppc64
    
    Presently, 64-bit applications on ppc64 may only use hugepages in the
    address region from 1-1.5T.  Furthermore, if hugepages are enabled in
    the kernel config, they may only use hugepages and never normal pages
    in this area.  This patch relaxes this restriction, allowing any
    address to be used with hugepages, but with a 1TB granularity.  That
    is if you map a hugepage anywhere in the region 1TB-2TB, that entire
    area will be reserved exclusively for hugepages for the remainder of
    the process's lifetime.  This works analagously to hugepages in 32-bit
    applications, where hugepages can be mapped anywhere, but with 256MB
    (mmu segment) granularity.
    
    This patch applies on top of the four level pagetable patch
    (http://patchwork.ozlabs.org/linuxppc64/patch?id=1936).

    If both CONFIG_XMON and CONFIG_XMON_DEFAULT is enabled in the .config,

    [PATCH] ppc64: Remove redundant abs_to_phys() macro
    
    abs_to_phys() is a macro that turns out to do nothing, and also has the
    unfortunate property that it's not the inverse of phys_to_abs() on iSeries.
    
    The following is for my benefit as much as everyone else.
    
    With CONFIG_MSCHUNKS enabled, the lmb code is changed such that it keeps
    a physbase variable for each lmb region. This is used to take the possibly
    discontiguous lmb regions and present them as a contiguous address space
    beginning from zero.
    
    In this context each lmb region's base address is its "absolute" base
    address, and its physbase is it's "physical" address (from Linux's point of
    view). The abs_to_phys() macro does the mapping from "absolute" to "physical".
    
    Note: This is not related to the iSeries mapping of physical to absolute
    (ie. Hypervisor) addresses which is maintained with the msChunks structure.
    And the msChunks structure is not controlled via CONFIG_MSCHUNKS.
    
    Once upon a time you could compile for non-iSeries with CONFIG_MSCHUNKS
    enabled. But these days CONFIG_MSCHUNKS depends on CONFIG_PPC_ISERIES, so
    for non-iSeries code abs_to_phys() is a no-op.
    
    On iSeries we always have one lmb region which spans from 0 to
    systemcfg->physicalMemorySize (arch/ppc64/kernel/iSeries_setup.c line 383).
    This region has a base (ie. absolute) address of 0, and a physbase address
    of 0 (as calculated in lmb_analyze() (arch/ppc64/kernel/lmb.c line 144)).
    
    On iSeries, abs_to_phys(aa) is defined as lmb_abs_to_phys(aa), which finds
    the lmb region containing aa (and there's only one, ie. 0), and then does:
    
     return lmb.memory.region[0].physbase + (aa - lmb.memory.region[0].base)
    
    physbase == base == 0, so you're left with "return aa".
    
    So remove abs_to_phys(), and lmb_abs_to_phys() which is the implementation
    of abs_to_phys() for iSeries.

    [PATCH] ppc64: Remove redundant use of pointers in lmb code
    
    The lmb code is all written to use a pointer to an lmb struct. But it's always
    the same lmb struct, called "lmb". So we take the address of lmb, call it
    _lmb and then start using _lmb->foo everywhere, which is silly.
    
    This patch removes the _lmb pointers and replaces them with direct references
    to the one "lmb" struct. We do the same for some _mem and _rsv pointers which
    point to lmb.memory and lmb.reserved respectively.
    
    This patch looks quite busy, but it's basically just:
    s/_lmb->/lmb./g
    s/_mem->/lmb.memory./g
    s/_rsv->/lmb.reserved./g
    s/_rsv/&lmb.reserved/g

    for now, but set them from the constant values.
    
    Replace msChunks_entry typedef with regular u32.
    
    Simplify msChunks_alloc() to manipulate klimit directly, rather than via
    a parameter.

    The firmware_features field of struct cpu_spec should really be a separate
    variable as the firmware features do not depend on the chip and the
    bitmask is constructed independently.  By removing it, we save 112 bytes
    from the cpu_specs array and we access the bitmask directly instead of via
    the cur_cpu_spec pointer.

    [PATCH] Move variables in ppc64 head.S from .data to .bss
    
    The ppc64 head.S defines several zero-initialized structures, such as
    the empty_zero_page and the kernel top-level pagetable.  Currently
    they are defined to be in the data section.  However, they're not used
    until after the bss is cleared, so this patch moves them to the bss,
    saving two and a half pages from the vmlinux.

    [PATCH] Fix apparent code overlap in ppc64 head.S
    
    An #if/#else construct near the top of ppc64's head.S appears to
    create overlapping sections of code for iSeries and pSeries (i.e. one
    thing on iSeries and something different in the same place on
    pSeries).  In fact, checking the various absolute offsets, it doesn't.
    This patch unravels the #ifdefs to make it more obvious what's going
    on.  This accomplishes another microstep towards a single kernel image
    which can boot both iSeries and pSeries.

    [PATCH] Move iSeries and common vectors into unused space in head.S
    
    In the ppc64 kernel head.S there is currently quite a lot of unused
    space between the naca (at fixed address 0x4000) and the fwnmi data
    area (at fixed address 0x7000).  This patch moves various exception
    vectors and support code into this region to use the wasted space.
    
    The functions load_up_fpu and load_up_altivec are moved down as well,
    since they are essentially continuations of the fp_unavailable_common
    and altivec_unavailable_common vectors, respectively.
    
    Likewise, the fwnmi vectors themselves are moved down into this area,
    because while the location of the fwnmi data area is fixed by the RPA,
    the vectors themselves can be anywhere sufficiently low.

    [PATCH] Remove NACA fixed address constraint
    
    Comments in head.S suggest that the iSeries naca has a fixed address,
    because tools expect to find it there.  The only tool which appears to
    access the naca is addRamDisk, but both the in-kernel version and the
    version used in RHEL and SuSE in fact locate the NACA the same way as
    the hypervisor does, by following the pointer in the hvReleaseData
    structure.
    
    Since the requirement for a fixed address seems to be obsolete, this
    patch removes the naca from head.S and replaces it with a normal C
    initializer.
    
    For good measure, it removes an old version of addRamDisk.c which was
    sitting, unused, in the ppc32 tree.

    [PATCH] ppc64: change duplicate Kconfig menu "General setup" to "Bus Options"
    
    arch/ppc64/Kconfig defines a "General setup" menu, but also sources
    init/Kconfig which also defines a "General setup" menu.  Both of these
    menus appear at the top level of make menuconfig.  Having two menus with
    the same name is confusing.  This patch renames the ppc64/Kconfig menu to
    be "Bus Options" and moves options in this menu which are not bus related
    to the end of the "Platform support" menu.
    
    There are many variations among architectures on the exact naming of the
    "Bus Options" menu.  I chose to use the simplest one, which is also used
    in arch/ppc/Kconfig.

    [PATCH] Four level pagetables for ppc64
    
    Implement 4-level pagetables for ppc64
    
    This patch implements full four-level page tables for ppc64, thereby
    extending the usable user address range to 44 bits (16T).
    
    The patch uses a full page for the tables at the bottom and top level,
    and a quarter page for the intermediate levels.  It uses full 64-bit
    pointers at every level, thus also increasing the addressable range of
    physical memory.  This patch also tweaks the VSID allocation to allow
    matching range for user addresses (this halves the number of available
    contexts) and adds some #if and BUILD_BUG sanity checks.
