The EXPERT menu list was recently broken by the insertion of a kconfig symbol (EMBEDDED) at the beginning of the EXPERT list of kconfig items.

F15h CPUs may report a non-DRAM address when reporting an error address belonging to a CC6 state save area. Add a workaround to detect this condition and compute the actual DRAM address of the error as documented in the Revision Guide for AMD Family 15h Models 00h-0Fh Processors. Signed-off-by:

F15h and later use a portion of DRAM as a CC6 storage area. BIOS programs D18F1x[17C:140,7C:40] DRAM Base/Limit accordingly by subtracting the storage area from the DRAM limit setting. However, in order for edac to consider that part of DRAM too, we need to include it into the per-node range. Signed-off-by:

Now that the security modules can decide whether they support the dcache RCU walk or not it's possible to make selinux a bit more RCU friendly. The SELinux AVC and security server access decision code is RCU safe. A specific piece of the LSM audit code may not be RCU safe. This patch makes the VFS RCU walk retry if it would hit the non RCU safe chunk of code. It will normally just work under RCU. This is done simply by passing the VFS RCU state as a flag down into the avc_audit() code and returning ECHILD there if it would have an issue. Based-on-patch-by:

Now that the whole dcache_hash_bucket crap is gone, go all the way and also remove the weird locking layering violations for locking the hash buckets. Add hlist_bl_lock/unlock helpers to move the locking into the list abstraction instead of requiring each caller to open code it. After all allowing for the bit locks is the whole point of these helpers over the plain hlist variant. Signed-off-by:

When we are waiting for the bit-lock to be released, and are looping over the 'cpu_relax()' should not be doing anything else - otherwise we miss the point of trying to do the whole 'cpu_relax()'. Do the preemption enable/disable around the loop, rather than inside of it. Noticed when I was looking at the code generation for the dcache __d_drop usage, and the code just looked very odd.

After 57db4e8d changed eCryptfs to write-back caching, eCryptfs page writeback updates the lower inode times due to the use of vfs_write() on the lower file. To preserve inode metadata changes, such as 'cp -p' does with utimensat(), we need to flush all dirty pages early in ecryptfs_setattr() so that the user-updated lower inode metadata isn't clobbered later in writeback. https://bugzilla.kernel.org/show_bug.cgi?id=33372Reported-by:

When failing to read the lower file's crypto metadata during a lookup, eCryptfs must continue on without throwing an error. For example, there may be a plaintext file in the lower mount point that the user wants to delete through the eCryptfs mount. If an error is encountered while reading the metadata in lookup(), the eCryptfs inode's size could be incorrect. We must be sure to reread the plaintext inode size from the metadata when performing an open() or setattr(). The metadata is already being read in those paths, so this adds minimal performance overhead. This patch introduces a flag which will track whether or not the plaintext inode size has been read so that an incorrect i_size can be fixed in the open() or setattr() paths. https://bugs.launchpad.net/bugs/509180 Cc: <stable@kernel.org> Signed-off-by:

If our space cache is wrong, we do the right thing and free up everything that we loaded, however we don't reset the total_bitmaps counter or the thresholds or anything. So in btrfs_remove_free_space_cache make sure to call free_bitmap() if it's a bitmap, this will keep us from panicing when we check to make sure we don't have too many bitmaps. Thanks, Signed-off-by:

For any given lower inode, eCryptfs keeps only one lower file open and multiplexes all eCryptfs file operations through that lower file. The lower file was considered "persistent" and stayed open from the first lookup through the lifetime of the inode. This patch keeps the notion of a single, per-inode lower file, but adds reference counting around the lower file so that it is closed when not currently in use. If the reference count is at 0 when an operation (such as open, create, etc.) needs to use the lower file, a new lower file is opened. Since the file is no longer persistent, all references to the term persistent file are changed to lower file. Locking is added around the sections of code that opens the lower file and assign the pointer in the inode info, as well as the code the fputs the lower file when all eCryptfs users are done with it. This patch is needed to fix issues, when mounted on top of the NFSv3 client, where the lower file is left silly renamed until the eCryptfs inode is destroyed. Signed-off-by:

vfs_rmdir() already calls d_delete() on the lower dentry. That was being duplicated in ecryptfs_rmdir() and caused a NULL pointer dereference when NFSv3 was the lower filesystem. Signed-off-by:

The ahci_pmp_attach() & ahci_pmp_detach() unmask port irqs, but they are also called during port initialization, before ahci host irq handler is registered. On ce4100 platform, this sometimes triggers "irq 4: nobody cared" message when loading driver. Fixed this by not touching the register if the port is in frozen state, and mark all uninitialized port as frozen. Signed-off-by:
