2006-06-25[PATCH] Clean up and refactor i386 sub-architecture setupJeremy Fitzhardinge
Clean up and refactor i386 sub-architecture setup. This change moves all the code from the asm-i386/mach-*/setup_arch_pre/post.h headers, into arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to setup_arch.h, and contains only things which should be in header files. It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.

2006-06-25[PATCH] Allow migration of mlocked pagesChristoph Lameter
Hugh clarified the role of VM_LOCKED. So we can now implement page migration for mlocked pages. Allow the migration of mlocked pages. This means that try_to_unmap must unmap mlocked pages in the migration case.

2006-06-25[PATCH] page migration: Support a vma migration functionChristoph Lameter
Hooks for calling vma specific migration functions With this patch a vma may define a vma->vm_ops->migrate function. That function may perform page migration on its own (some vmas may not contain page structs and therefore cannot be handled by regular page migration. Pages in a vma may require special preparatory treatment before migration is possible etc) . Only mmap_sem is held when the migration function is called. The migrate() function gets passed two sets of nodemasks describing the source and the target of the migration. The flags parameter either contains MPOL_MF_MOVE which means that only pages used exclusively by the specified mm should be moved or MPOL_MF_MOVE_ALL which means that pages shared with other processes should also be moved. The migration function returns 0 on success or an error condition. An error condition will prevent regular page migration from occurring. On its own this patch cannot be included since there are no users for this functionality. But it seems that the uncached allocator will need this functionality at some point.

2006-06-25[PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHMChristoph Lameter
Remove VM_LOCKED before remap_pfn range from device drivers and get rid of VM_SHM. remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not place pages on the LRU. The pages are therefore never subject to swap anyways. Remove all the vm_flags settings before calling remap_pfn_range. After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

2006-06-25[PATCH] AOP_TRUNCATED_PAGE victims in read_pages() belong in the LRUZach Brown
AOP_TRUNCATED_PAGE victims in read_pages() belong in the LRU Nick Piggin rightly pointed out that the introduction of AOP_TRUNCATED_PAGE to read_pages() was wrong to leave A_T_P victim pages in the page cache but not put them in the LRU. Failing to do so hid them from the VM. A_T_P just means that the aop method unlocked the page rather than performing IO. It would be very rare that the page was truncated between the unlock and testing A_T_P. So we leave the pages in the LRU for likely reuse soon rather than backing them back out of the page cache. We do this by matching the behaviour before the A_T_P introduction which added pages to the LRU regardless of what ->readpage() did. This doesn't include the unrelated cleanup in Nick's initial fix which changed read_pages() to return void to match its only caller's behaviour of ignoring errors.

2006-06-24Revert "[PATCH] usb: drivers/usb/core/devio.c dereferences a userspace pointer"Linus Torvalds
This reverts commit 786dc1d3d7333f269e17d742886eac2188a2d9cc. As Al so eloquently points out, the patch is crap. The old code was fine, the new code was bogus. It never dereferenced a user pointer, the "->" operator was to an array member, which gives the _address_ of the member (in user space), not an actual dereference at all.

Patch from Daniel Jacobowitz In order for userspace to find saved coprocessor registers, move them from struct rt_sigframe into struct ucontext. Also allow space for glibc's sigset_t, so that userspace and kernelspace can use the same ucontext layout. Define the magic numbers for iWMMXt in the header file for easier reference. Include the size of the coprocessor data in the magic numbers. Also define magic numbers and layout for VFP, not yet saved.
