2012-05-29lcd: add callbacks for early fb event blank supportInki Dae
This patchset adds early fb blank feature that a callback of lcd panel driver is called prior to specific fb driver's one. In the case of MIPI-DSI based video mode LCD Panel, for lcd power off, the power off commands should be transferred to lcd panel with display and mipi-dsi controller enabled because the commands is set to lcd panel at vsync porch period. and in opposite case, the callback of fb driver should be called prior to lcd panel driver's one because of same issue. Also if fb_blank mode is changed to FB_BLANK_POWERDOWN then display controller would be off(clock disable) but lcd panel would be still on. at this time, you could see some issue like sparkling on lcd panel because video clock to be delivered to ldi module of lcd panel was disabled. this issue could occurs for all lcd panels. The callback order is as the following: at fb_blank function of fbmem.c -> fb_notifier_call_chain(FB_EARLY_EVENT_BLANK) -> lcd panel driver's early_set_power() -> info->fbops->fb_blank() -> spcefic fb driver's fb_blank() -> fb_notifier_call_chain(FB_EVENT_BLANK) -> lcd panel driver's set_power() -> fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) if info->fops->fb_blank() was failed. fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) would be called to revert the effects of previous FB_EARLY_EVENT_BLANK call. and note that if early_set_power() of lcd_ops is NULL then early fb blank callback would be ignored. This patch: Add early_set_power and r_early_set_power callbacks. early_set_power callback is called prior to fb_blank() of fbmem.c and r_early_set_power callback is called if fb_blank() was failed to revert the effects of the early_set_power call of lcd panel driver.

2012-05-29mm/fs: route MADV_REMOVE to FALLOC_FL_PUNCH_HOLEHugh Dickins
Now tmpfs supports hole-punching via fallocate(), switch madvise_remove() to use do_fallocate() instead of vmtruncate_range(): which extends madvise(,,MADV_REMOVE) support from tmpfs to ext4, ocfs2 and xfs. There is one more user of vmtruncate_range() in our tree, staging/android's ashmem_shrink(): convert it to use do_fallocate() too (but if its unpinned areas are already unmapped - I don't know - then it would do better to use shmem_truncate_range() directly).

2012-05-29ACPI / PM: Make acpi_pm_device_sleep_state() follow the specificationRafael J. Wysocki
The comparison between the system sleep state being entered and the lowest system sleep state the given device may wake up from in acpi_pm_device_sleep_state() is reversed, because the specification (ACPI 5.0) says that for wakeup to work: "The sleeping state being entered must be less than or equal to the power state declared in element 1 of the _PRW object." In other words, the state returned by _PRW is the deepest (lowest-power) system sleep state the device is capable of waking up the system from. Moreover, acpi_pm_device_sleep_state() also should check if the wakeup capability is supported through ACPI, because in principle it may be done via native PCIe PME, for example, in which case _SxW should not be evaluated.

2012-05-29ACPI / PM: Make __acpi_bus_get_power() cover D3cold correctlyRafael J. Wysocki
After recent changes of the ACPI device power states definitions, if power resources are not used for the device's power management, the state returned by __acpi_bus_get_power() cannot exceed D3hot, because the return values of _PSC are 0 through 3. However, if the _PR3 method is not present for the device and _PS3 returns 3, we have to assume that the device is in D3cold, so the value returned by __acpi_bus_get_power() in that case should be 4. Similarly, acpi_power_get_inferred_state() should take the power resources for the D3hot state into account in general, so that it can return 3 if those resources are "on" or 4 (D3cold) otherwise. Fix the the above two issues and make sure that if both _PSC and _PR3 are present for the device, the power resources listed by _PR3 will be used to determine if the number 3 returned by _PSC is meant to represent D3cold or D3hot.

2012-05-29ACPI / PM: Generate wakeup events on fixed power buttonDaniel Drake
When the system is woken up by the ACPI fixed power button, currently there is no way of userspace becoming aware that the power button was pressed. OLPC would like to know this, so that we can respond appropriately. For example, if the system was woken up by a network packet, we know we can go back to sleep very quickly. But if the user explicitly woke the system with the power button, we're going to want to stay awake for a while. The wakeup count mechanism seems like a good fit for communicating this. Mark the fixed power button as wakeup-enabled, and increment its wakeup counter when the system is woken with the power button. (The wakeup counter is also incremented when the power button is pressed during system operation; this is already handled by an existing acpi-button codepath).

2012-05-29drm/i915: Reset last_retired_head when resetting ringChris Wilson
When we reset the ring control registers, including the HEAD and TAIL of the ring, we also need to reset associated state. In this instance, we were failing to reset the cached value of ring->last_retired_head and so upon the first request for more space following a resume would potentially (depending on a narrow race window) believe that the HEAD had advanced much further than reality. This is a regression from: commit a71d8d94525e8fd855c0466fb586ae1cb008f3a2 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Feb 15 11:25:36 2012 +0000 drm/i915: Record the tail at each request and use it to estimate the head Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: stable@vger.kernel.org # 3.4 Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2012-05-29mtd: nand: fix scan_read_raw_oobDmitry Maluka
It seems there is a bug in scan_read_raw_oob() in nand_bbt.c which should cause wrong functioning of NAND_BBT_SCANALLPAGES option. Artem: the patch did not apply and I had to amend it a bit. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Cc: stable@kernel.org
2012-05-29mtd: docg3 fix in-middle of blocks readsRobert Jarzmik
Corner case reads do not work, and return false data and ECC. This case is typically seen in a ubifs usage, with a read of type: - docg3 docg3: doc_read_oob(from=14882415, mode=1, data=(c30eca40:12), oob=( (null):0)) This results in the following reads: - docg3 docg3: doc_read_data_area(buf= (null), len=111) - docg3 docg3: doc_read_data_area(buf=c30eca40, len=12) - docg3 docg3: doc_read_data_area(buf= (null), len=389) - docg3 docg3: doc_read_data_area(buf= (null), len=0) - docg3 docg3: doc_read_data_area(buf= (null), len=16) If we suppose that the pages content is : - bytes 0 .. 111 : 0x0a - bytes 112 .. 255 : 0x0f Then the returned bytes will be : - 111 times 0x0a (correct) - 0x0a 2 times and 0x0f 10 times (incorrect, should be 0x0a,0x0f) - 0x0f 389 times (correct) - nothing - correct OOB The reason seams that the first 111 bytes read ends between the 2 docg3 planes, and that the first following read (in the 12 bytes sequence, read of 16 bit word) returns the byte of the rightmost plane duplicated in high and lower byte of the word. Fix this behaviour by ensuring that if the previous read ended up in-between the 2 planes, there will be a first 1 byte read to get back to the beginning of leftmost plane.

2012-05-28i7core: fix ranks information at the per-channel structMauro Carvalho Chehab
There is a flag at the per-channel struct that indicates if there are any 4R dimm on it. The way the presence of this flag were reported is not ok, as it might give the false idea that the channel were filled with 2R memories: [ 580.588701] EDAC DEBUG: get_dimm_config: Ch1 phy rd1, wr1 (0x063f7431): 2 ranks, UDIMMs [ 580.588704] EDAC DEBUG: get_dimm_config: dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400 (in this case, just one 1R memory is filled on channel 1) So, use a better way to represent the per-channel ranks information. After the patch, it will show: [ 2002.233978] EDAC DEBUG: get_dimm_config: Ch0 phy rd0, wr0 (0x063f7431): UDIMMs [ 2002.233982] EDAC DEBUG: get_dimm_config: dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400 [ 2002.233988] EDAC DEBUG: get_dimm_config: dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400 (in this case, there isn't any 4R memories) Reported-by: Borislav Petkov <borislav.petkov@amd.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
