2010-05-20nvmap: fix unpin/pin race condition with RECLAIM_UNPINNED_VMAntti Hatala
_nvmap_handle_unpin needs to acquire the mru_vma_lock before decrementing the pin count, to ensure that a decrement to zero and insertion on the MRU VMA list appears atomic with respect to a second client calling _nvmap_handle_pin on the same handle; otherwise, the two clients race and the pin operation may trigger a BUG because the handle has a valid IOVMM area but is not located on any MRU VMA list. also, clean up some additional allocation-inside-spinlock issues; release the MRU VMA lock before calling tegra_iovmm_create_vm, and reacquire the lock after returning.

2010-05-17tegra mmc: enable MMC_UNSAFE_RESUME config for tegra_harmony_androidDeepesh Gujarathi
Normally, when the system goes into suspend, all the storage cards are removed and later re-enumerated upon resume. During re-enumeration the device name and number are not guaranteed to be the same as they were during bootup. This can cause data corruption on cards. When the MMC_UNSAFE_RESUME config is enabled, it will prevent kernel from unmounting the mmc cards before suspend. Upon resume the cards will still be using the same device id as they were before suspend. This change seems to fix a lot of mmc related issues that occur during LP0 transitions. partial fix for Bug 679959 Change-Id: Ib90f95ebbc81c5b6e9e83e740ece31f914a262eb Reviewed-on: http://git-master/r/1412 Reviewed-by: Narendra Damahe <ndamahe@nvidia.com> Tested-by: Narendra Damahe <ndamahe@nvidia.com> Reviewed-by: Gary King <gking@nvidia.com>

In SNDRV_PCM_TRIGGER_STOP state of the driver, if a buffer gets queued then it might not be returned back as it never gets rendered. In this scenario play_thread never exits as it keep on waiting for receiving all the buffers back from mixer before exiting. This is to solve bug 684393. In case of START->STOP->START scenario (happens in case of underruns), without closing the stream, there will not be any buffer loss as buffers are queued by application at appl_ptr and they remain there, once next START is called, they will be picked up for the playback.

2010-05-06tegra power: Fix gart suspend/resume operationstkasivajhula
Apply proper barriers to suspend/resume operations. The dmb() in suspend is required to prevent a race between the next ENTRY_ADDR write and the previous ENTRY_DATA read. The dsb+outer_sync() in resume() is needed to ensure that the writes and reads occur as expected.

2010-05-05fsl udc: Fix cable connect/disconnect checkingVenkat Moganty
On VBUS interrupt irq acknowledges the VBUS interrupt and schedules the work thread for powering/up down the USB phy and clocks based on the VBUS status. But, in the work thread instead of checking the VBUS status directly, rechecking the interrupt status which is already disabled. This is fixed by checking the vbus status only in the work thread for controlling the power up/down sequence. Due to the disconnect problem power numbers increased when there is no USB cable connected to the system.

2010-05-04tegra kbc: Fixing android boot if key is kept press during boot.Laxman Dewangan
Following changes are done: - Created the new workqueue for the kbc scan process. On default workqueue, the msleep() was not causing the schedule() to booting process. - If there is no entry in fifo then wait for the next scan to complete before re-reading the number of entries in the fifo. if there is no entry then rep key released. - Fixed timing calculation and size of the event entry array. - Fixed the debaunce count calculation from debaunce time from odm. Tested on whistler, with normal boot as well as with continous key pressed d the entire boot time.
