2013-06-19perf: Add const qualifier to perf_pmu_register's 'name' argMischa Jonker

2013-06-18cgroup: disallow rename(2) if sane_behaviorTejun Heo
cgroup's rename(2) isn't a proper migration implementation - it can't move the cgroup to a different parent in the hierarchy. All it can do is swapping the name string for that cgroup. This isn't useful and can mislead users to think that cgroup supports proper cgroup-level migration.

2013-06-17USB: EHCI: tegra: fix circular module dependenciesStephen Warren
The Tegra EHCI driver directly calls various functions in the Tegra USB PHY driver. The reverse is also true; the PHY driver calls into the EHCI driver. This is problematic when the two are built as modules. The calls from the PHY to EHCI driver were originally added in commit bbdabdb "usb: add APIs to access host registers from Tegra PHY", for the following reasons: 1) The register being touched is an EHCI register, so logically only the EHCI driver should touch it. 2) (1) implies that some locking may be needed to correctly implement the r/m/w access to this shared register. 3) We were expecting to pass only the PHY register space to the Tegra PHY driver, and hence it would not have access to touch the shared registers. To solve this, that commit added functions in the EHCI driver to touch the shared register on behalf of the PHY driver. In practice, we ended up not having any locking in the implementaiton of those functions, and I've been led to believe this is safe. Equally, (3) did not happen either. Hence, it is possible for the PHY driver to touch the shared register directly. Given that, this patch moves the code to touch the shared register back into the PHY driver, to eliminate the module problems. If we actually need locking or co-ordination in the future, I propose we put the lock support into some pre-existing core module, or into a third separate module, in order to avoid the circular dependencies. I apologize for my contribution to code churn here.

2013-06-17USB: serial: increase the number of devices we supportGreg Kroah-Hartman
We had the limit of 255 USB to serial devices on one system for almost 15 years, with no complaints. But now it's time to move on from these tiny "baby" systems, and bump the number up to 512, which should last us a few more years: "512 is a nice number" -- Tobias Winter Note, this is still a static value, and uses up tty core memory with this many tty devices allocated.

2013-06-17USB: serial: make minor allocation dynamicGreg Kroah-Hartman
This moves the allocation of minor device numbers from a static array to be dynamic, using the idr interface. This means that you could potentially get "gaps" in a minor number range for a single USB serial device with multiple ports, but all should still work properly. We remove the 'minor' field from the usb_serial structure, as it no longer makes any sense for it (use the field in the usb_serial_port structure if you really want to know this number), and take the fact that we were overloading a number in this field to determine if we had initialized the minor numbers or not, and just use a flag variable instead. Note, we still have the limitation of 255 USB to serial devices in the system, as that is all we are registering with the TTY layer at this point in time.
