- get_user() __gu_val should be unsigned long (same as with i386 patch) - __copy_to_user() et.al. didn't have proper type checking - documented the casts in __copy_tofrom_user() calls with __force. Signed-off-by:

Someone thought it would be clever if proc code ignores removal of non-existent entries. Hence, we missed that /proc/net/stat/ip_conntrack is never removed on module removal or init failure. Found by nfsim. Signed-off-by: -

Somehow parport_pc.c ended up with mixed old-style and new-style module parameters, but mixing them is not allowed. Use module_param() instead of MODULE_PARM() -- cannot be mixed. Signed-off-by:

sparc32 had a conflicting _exit, removed the line from asm- sparc/unistd.h.

The latter hunk of the forwarded patch has already been applied, so please apply the patch as it appears in the un-forwarded part. I've taken some liberties in adding the Acked/Signed-off lines in what I hope is an agreeable way.

Chris Newport and Thomas Bogendoerfer have been working to get the sun4d port functional again. This patch updates 2.6.10-rc3 to a current snapshot of their work. It does the following 3 things: (1) add sun4d hook to sbus_bus_ranges_init() (2) fix up pgd_offset() call in sun4d iommu code (3) fix up sun4d's definition of current Signed-off-by:

Converted to true 4levels. The address space per process is expanded to 47bits now, the supported physical address space is 46bits. Lmbench fork/exit numbers are down a few percent because it has to walk much more pagetables, but some planned future optimizations will hopefully recover it. See Documentation/x86_64/mm.txt for more details on the memory map. Signed-off-by:

Nick Piggin authored
Add a temporary "fallback" header so architectures can run with the 4level patgetables patch without modification. All architectures should be converted to use the folding headers (include/asm-generic/pgtable-nop?d.h) as soon as possible, and the fallback header removed. Make all architectures include the fallback header, except i386, because that architecture has earlier been converted to use pgtable-nopmd.h under the 3 level system, which is not compatible with the fallback header.

Extend the Linux MM to 4level page tables. This is the core patch for mm/*, fs/*, include/linux/* It breaks all architectures, which will be fixed in separate patches. The conversion is quite straight forward. All the functions walking the page table hierarchy have been changed to deal with another level at the top. The additional level is called pml4. mm/memory.c has changed a lot because it did most of the heavy lifting here. Most of the changes here are extensions of the previous code. Signed-off-by:

Generic headers to fold the 4-level pagetable into 3 levels. Signed-off-by:

Nick Piggin authored
Rename clear_page_tables to clear_page_range. clear_page_range takes byte ranges, and aggressively frees page table pages. Maybe useful to control page table memory consumption on 4-level architectures (and even 3 level ones). Possible downsides are: - flush_tlb_pgtables gets called more often (only a problem for sparc64 AFAIKS). - the opportunistic "expand to fill PGDIR_SIZE hole" logic that ensures something actually gets done under the old system is still in place. This could sometimes make unmapping small regions more inefficient. There are some other solutions to look at if this is the case though. Signed-off-by:
