2012-10-09mm: kill vma flag VM_RESERVED and mm->reserved_vm counterKonstantin Khlebnikov
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

2007-07-30[SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.cDavid S. Miller
They are handled in a ->compat_ioctl() handler, so it's just noise when compat_ioctl.c warns which occurs when they are used on non-SBUS framebuffer devices. Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-22[SPARC]: Respect vm_page_prot in io_remap_page_range().David S. Miller

2006-01-17[SPARC]: Fix sbusfb build.David S. Miller
sbusfb_compat_ioctl() needs to return int, not long, as that is what the fb_ops->fb_compat_ioctl method prototype wants. Need to git rid of the "struct file *file" first argument to fbiogetputcmap() and fbiogscursor() to match calls done in sbusfb_compat_ioctl(). Signed-off-by: David S. Miller <davem@davemloft.net>
2006-01-17[PATCH] fix up sbuslib for new fb_comapt_ioctl prototypeChristoph Hellwig
After ages my fb ioctl prototype cleanup finally got in. Unfortunately the patch are so old that the sbus compat_ioctl helper didn't exist back then, so it's not covered. This patch should fix that issue. Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: "David S. Miller" <davem@davemloft.net> Cc: "Antonino A.

2005-11-12[SBUSFB]: implement ->compat_ioctlChristoph Hellwig
This patch adds a new function, sbusfb_compat_ioctl() to drivers/video/sbuslib.c and uses it as compat_ioctl in all sbus fb drivers This remove the last per-arch compat ioctl bits in arch/sparc64/kernel/ioctl32.c so it would be nice if people could test if this actually copiles and works and if yes apply it :) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
