Previous reset code leaded to computer hard lockup (need to unplug the power too reboot the computer) on various configuration. This patch change the reset code to avoid hard lockup. The GPU reset is failing most of the time but at least user can log in remotely or properly shutdown the computer. Two issues were leading to hard lockup : - Writting to the scratch register lead to hard lockup most likely because the write back mecanism is in fuzy state after GPU lockup. - Resetting the GPU memory controller and not reinitializing it after leaded to hard lockup. We did only reinitialize in case of successfull reset thus unsuccessfull reset quickly leaded to hard lockup.

Convert most AGP chipset to use scratch page as default entries. This help avoiding GPU querying 0 address and trigger computer fault. With KMS and memory manager we bind/unbind AGP memory constantly and it seems that some GPU are still doing AGP traffic even after GPU report being idle with the memory segment. Tested (radeon GPU KMS + Xorg + compiz + glxgears + quake3) on : - SIS 1039:0001 & 1039:0003 - Intel 865 8086:2571 Compile tested for other bridges V2 enable scratch page on uninorth V3 fix unbound check in uninorth insert memory (Michel Dänzer) V4 rebase on top of drm-next branch with the lastest intel AGP changeset (stable should use version V3 of the patch) Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: Dave Airlie <airlied@redhat.com>

On fault the driver is given the opportunity to perform any operation it sees fit in order to place the buffer into a CPU visible area of memory. This patch doesn't break TTM users, nouveau, vmwgfx and radeon should keep working properly. Future patch will take advantage of this infrastructure and remove the old path from TTM once driver are converted. V2 return VM_FAULT_NOPAGE if callback return -EBUSY or -ERESTARTSYS V3 balance io_mem_reserve and io_mem_free call, fault_reserve_notify is responsible to perform any necessary task for mapping to succeed V4 minor cleanup, atomic_t -> bool as member is protected by reserve mecanism from concurent access V5 the callback is now responsible for iomapping the bo and providing a virtual address this simplify TTM and will allow to get rid of TTM_MEMTYPE_FLAG_NEEDS_IOREMAP V6 use the bus addr data to decide to ioremap or this isn't needed but we don't necesarily need to ioremap in the callback but still allow driver to use static mapping Signed-off-by: Jerome Glisse <jglisse@redhat.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

The recent anon_vma fixes cause many anonymous pages to end up in the parent process anon_vma, even when the page is exclusively owned by the current process. Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

Since tmpfs has no persistent storage, it pins all its dentries in memory so they have d_count=1 when other file systems would have d_count=0. ->lookup is only used to create new dentries. If the caller doesn't instantiate it, it's freed immediately at dput(). ->readdir reads directly from the dcache and depends on the dentries being hashed. When an ecryptfs mount is mounted, it associates the lower file and dentry with the ecryptfs files as they're accessed. When it's umounted and destroys all the in-memory ecryptfs inodes, it fput's the lower_files and d_drop's the lower_dentries. Commit 4981e081 added this and a d_delete in 2008 and several months later commit caeeeecf removed the d_delete. I believe the d_drop() needs to be removed as well. The d_drop effectively hides any file that has been accessed via ecryptfs from the underlying tmpfs since it depends on it being hashed for it to be accessible. I've removed the d_drop on my development node and see no ill effects with basic testing on both tmpfs and persistent storage. As a side effect, after ecryptfs d_drops the dentries on tmpfs, tmpfs BUGs on umount. This is due to the dentries being unhashed. tmpfs->kill_sb is kill_litter_super which calls d_genocide to drop the reference pinning the dentry. It skips unhashed and negative dentries, but shrink_dcache_for_umount_subtree doesn't. Since those dentries still have an elevated d_count, we get a BUG(). This patch removes the d_drop call and fixes both issues.

If the lower file system driver has extended attributes disabled, ecryptfs' own access functions return -ENOSYS instead of -EOPNOTSUPP.

Create a getattr handler for eCryptfs symlinks that is capable of reading the lower target and decrypting its path. Prior to this patch, a stat's st_size field would represent the strlen of the encrypted path, while readlink() would return the strlen of the decrypted path. This could lead to confusion in some userspace applications, since the two values should be equal. https://bugs.launchpad.net/bugs/524919Reported-by: Loïc Minier <loic.minier@canonical.com> Cc: stable@kernel.org Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
