2015-09-14usb: musb: ensure in peripheral mode when checking sessionBin Liu1-0/+1
The change ensures otg is not in a A- state when checking for VBUS in peripheral mode. musb_start() where VBUS checking is in can be called in many situations. One example is in babble recovery routine, in which otg is transitioning from A-HOST to A-WAIT-BCON, but VBUS discharge takes time, so musb->is_active could be set to 1 due to this improper checking, then it causes musb_bus_suspend() failed which leads to warning log message flooding.

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.

2015-09-14arm64: pgtable: use a single bit for PTE_WRITE regardless of DBMWill Deacon1-5/+1
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 Marinas1-2/+2
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.

2015-09-14drm/vmwgfx: Map the fifo as cachedThomas Hellstrom2-9/+2
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 Hellstrom6-17/+39
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.

2015-09-13thermal: db8500_cpufreq_cooling: Fix module autoload for OF platform driverLuis de Bethencourt1-0/+1
This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt <[email protected]> Signed-off-by: Eduardo Valentin <[email protected]>
2015-09-13thermal: cpu_cooling: Add MAINTAINERS entryViresh Kumar1-0/+10
None of the patches are reaching Viresh or Daniel directly as get_maintainers doesn't report us as maintainers. Looks like file header or history of commits isn't able to do that properly. Add a separate entry for cpu_cooling driver in MAINTAINERS.
