drm/panfrost: Handle page mapping failure
When mapping the pages of a BO, either a heap type at page fault time or else a non-heap BO at object creation time, if the ARM page table mapping function fails, we unmap what had been mapped so far and bail out.

Miller <davem@davemloft.net> 2014-11-16dcbnl : Disable software interrupts before taking dcb_lockAnish Bhatt Solves possible lockup issues that can be seen from firmware DCB agents calling into the DCB app api. DCB firmware event queues can be tied in with NAPI so that dcb events are generated in softIRQ context. This can results in calls to dcb_*app() functions which try to take the dcb_lock. If the the event triggers while we also have the dcb_lock because lldpad or some other agent happened to be issuing a get/set command we could see a cpu lockup. This code was not originally written with firmware agents in mind, hence grabbing dcb_lock from softIRQ context was not considered.

Miller <davem@davemloft.net> 2014-07-30dcbnl : Fix misleading dcb_app->priority explanationAnish Bhatt Current explanation of dcb_app->priority is wrong. It says priority is expected to be a 3-bit unsigned integer which is only true when working with DCBx-IEEE. Use of dcb_app->priority by DCBx-CEE expects it to be 802.1p user priority bitmap. Updated accordingly This affects the cxgb4 driver, but I will post those changes as part of a larger changeset shortly.
