The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the sample period of a running perf_event. Consequently, when calculating the next event period, the new period will only be considered after the previous one has overflowed.
This patch changes the calculation of the remaining event ticks so that they are offset if the period has changed.
See commit 3581fe0ef37c ("ARM: 7556/1: perf: fix updated event period in response to PERF_EVENT_IOC_PERIOD") for details.

struct ufs_dev_cmd is the main container that supports device management commands. In the case of a read descriptor request, we assume that the proper space was allocated in dev_cmd to hold the returning descriptor.
This is no longer true, as there are flows that doesn't use dev_cmd for device management requests, and was wrong in the first place.

Enabling sysfs attribute bridge_hostnotify triggers a series of udev events for the MAC addresses of all currently connected peers. In case no VLAN is set for a peer, the device reports the corresponding MAC addresses with VLAN ID 4096. This currently results in attribute VLAN=4096 for all non-VLAN interfaces in the initial series of events after host-notify is enabled.
Instead, no VLAN attribute should be reported in the udev event for non-VLAN interfaces.
Only the initial events face this issue. For dynamic changes that are reported later, the device uses a validity flag.
This also changes the code so that it now sets the VLAN attribute for MAC addresses with VID 0. On Linux, no qeth interface will ever be registered with VID 0: Linux kernel registers VID 0 on all network interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0. Peers with other OSs could register MACs with VID 0.

Some chips have attributes which exist on more than one page but the attribute is not presently marked as paged. This causes the attributes to be generated with the same label, which makes it impossible for userspace to tell them apart.
Marking all such attributes as paged would result in the page suffix being added regardless of whether they were present on more than one page or not, which might break existing setups. Therefore, we add a second check which treats the attribute as paged, even if not marked as such, if it is present on multiple pages.
