2015-09-14usb: gadget: fix possible regression introduced with ep->claimedRobert Baldyga
This patch fixes possible regression introduced by patch reworking endpoint claiming mechanism. It restores setring ep->driver_data to NULL in usb_ep_autoconfig_reset(), which was removed by patch commit cc476b42a39d.

2015-09-14thermal: power_allocator: don't require tzp to be present for the thermal zoneJavi Merino
Thermal zones created using thermal_zone_device_create() may not have tzp. As the governor gets its parameters from there, allocate it while the governor is bound to the thermal zone so that it can operate in it. In this case, tzp is freed when the thermal zone switches to another governor.

2015-09-14thermal: power_allocator: relax the requirement of two passive trip pointsJavi Merino
The power allocator governor currently requires that the thermal zone has at least two passive trip points. If there aren't, the governor refuses to bind to the thermal zone. This commit relaxes that requirement. Now the governor will bind to all thermal zones regardless of how many trip points they have.

2015-09-14thermal: power_allocator: relax the requirement of a sustainable_power in tzpJavi Merino
The power allocator governor currently requires that a sustainable power is passed as part of the thermal zone's thermal zone parameters. If that parameter is not provided, it doesn't register with the thermal zone. While this parameter is strongly recommended for optimal performance, it doesn't need to be mandatory. Relax the requirement and allow the governor to bind to thermal zones that don't provide it by estimating it from the cooling devices' power model.

2015-09-14arm64: pgtable: use a single bit for PTE_WRITE regardless of DBMWill Deacon
Depending on CONFIG_ARM64_HW_AFDBM, we use either bit 57 or 51 of the pte to represent PTE_WRITE. Given that bit 51 is reserved prior to ARMv8.1, we can just use that bit regardless of the config option. That also matches what happens if a kernel configured with ARM64_HW_AFDBM=y is run on a CPU without the DBM functionality.

2015-09-14arm64: Fix the pte_hw_dirty() check when AF/DBM is enabledCatalin Marinas
Commit 2f4b829c625e ("arm64: Add support for hardware updates of the access and dirty pte bits") introduced support for handling hardware updates of the access flag and dirty status. The PTE is automatically dirtied in hardware (if supported) by clearing the PTE_RDONLY bit when the PTE_DBM/PTE_WRITE bit is set. The pte_hw_dirty() macro was added to detect a hardware dirtied pte. The pte_dirty() macro checks for both software PTE_DIRTY and pte_hw_dirty(). Functions like pte_modify() clear the PTE_RDONLY bit since it is meant to be set in set_pte_at() when written to memory. In such cases, pte_hw_dirty() would return true even though such pte is clean. This patch changes pte_hw_dirty() to test the PTE_DBM/PTE_WRITE bit together with PTE_RDONLY.

While the following commit: 37868fe113 ("x86/ldt: Make modify_ldt synchronous") added a nice comment explaining that Xen needs page-aligned whole page chunks for guest descriptor tables, it then nevertheless used kzalloc() on the small size path. As I'm unaware of guarantees for kmalloc(PAGE_SIZE, ) to return page-aligned memory blocks, I believe this needs to be switched back to __get_free_page() (or better get_zeroed_page()).

2015-09-14drm/vmwgfx: Map the fifo as cachedThomas Hellstrom
On the guest kernel side, previously the FIFO has been mapped write- combined. This has worked since VMs up to now has not honored the mapping type and mapped the FIFO cached anyway. Since the FIFO is accessed cached by the CPU on the virtual device side, this leads to inconsistent mappings once the guest starts to honor the mapping types. So ask for cached mappings when we map the FIFO. We do this by using ioremap_cache() instead of ioremap_wc(), and remove the MTRR setup. On the TTM side, MOBs, GMRs and VRAM buffers are already requesting cached mappings for kernel- and user-space.

2015-09-14drm/vmwgfx: Fix up user_dmabuf refcountingThomas Hellstrom
If user space calls unreference on a user_dmabuf it will typically kill the struct ttm_base_object member which is responsible for the user-space visibility. However the dmabuf part may still be alive and refcounted. In some situations, like for shared guest-backed surface referencing/opening, the driver may try to reference the struct ttm_base_object member again, causing an immediate kernel warning and a later kernel NULL pointer dereference. Fix this by always maintaining a reference on the struct ttm_base_object member, in situations where it might subsequently be referenced.
