2017-07-04ovl: generalize ovl_create_workdir()Amir Goldstein
Pass in the subdir name to create and specify if subdir is persistent or if it should be cleaned up on every mount. Move fallback to readonly mount on failure to create dir and print of error message into the helper. This function is going to be used for creating the persistent 'index' dir under workbasedir.

2017-07-04ovl: get exclusive ownership on upper/work dirsAmir Goldstein
Bad things can happen if several concurrent overlay mounts try to use the same upperdir/workdir path. Try to get the 'inuse' advisory lock on upperdir and workdir. Fail mount if another overlay mount instance or another user holds the 'inuse' lock on these directories. Note that this provides no protection for concurrent overlay mount that use overlapping (i.e. descendant) upper/work dirs.

2017-07-04vfs: introduce inode 'inuse' lockAmir Goldstein
Added an i_state flag I_INUSE and helpers to set/clear/test the bit. The 'inuse' lock is an 'advisory' inode lock, that can be used to extend exclusive create protection beyond parent->i_mutex lock among cooperating users. This is going to be used by overlayfs to get exclusive ownership on upper and work dirs among overlayfs mounts.

2017-07-04ovl: use ovl_inode mutex to synchronize concurrent copy upAmir Goldstein
Use the new ovl_inode mutex to synchonize concurrent copy up instead of the super block copy up workqueue. Moving the synchronization object from the overlay dentry to the overlay inode is needed for synchonizing concurrent copy up of lower hardlinks to the same upper inode.

2017-07-04ovl: fix nlink leak in ovl_rename()Amir Goldstein
This patch fixes an overlay inode nlink leak in the case where ovl_rename() renames over a non-dir.

2017-07-04ACPI / scan: Indicate to platform when hot remove returns busyLee, Chun-Yi
In hotplug logic, it always indicates non-specific failure to platform through _OST when handing ACPI hot-remove event failed. Then platform terminates the hot-remove process but it can not identify the reason. Base on current hot-remove code, there have two situations that it returns busy: - OSPM try to offline an individual device, but the device offline function returns "busy". - When the ejection event is applied to an "not offlined yet" container. OSPM sends a kobject change event to userspace and returns "busy". Both of them will returns -EBUSY to ACPI device hotplug function. Then, the hotplug function indicates non-specific failure to platform just like for any other error, e.g. -ENODEV or -EIO. The benefit to the platform for identifying the OS "busy" state is that it can use a different approach to handle the "busy" instead of simply terminating the hot-remove operation for an unknown reason. For example, the platform can wait for a while and then re-trigger hot-remove.

2017-07-04ACPI: SPCR: Workaround for APM X-Gene 8250 UART 32-alignment errataLoc Ho
APM X-Gene verion 1 and 2 have an 8250 UART with its register aligned to 32-bit. In addition, the latest released BIOS encodes the access field as 8-bit access instead 32-bit access. This causes no console with ACPI boot as the console will not match X-Gene UART port due to the lack of mmio32 option.

2017-07-04ACPI: SPCR: Use access width to determine mmio usageLoc Ho
The current SPCR code does not check the access width of the MMIO, and uses a default of 8bit register accesses. This prevents devices that only do 16 or 32bit register accesses from working. By simply checking this field and setting the MMIO string appropriately, this issue can be corrected. To prevent any legacy issues, the code will default to 8bit accesses if the value is anything but 16 or 32.
