2011-04-13vm: fix vm_pgoff wrap in stack expansionLinus Torvalds
Commit 982134ba6261 ("mm: avoid wrapping vm_pgoff in mremap()") fixed the case of a expanding mapping causing vm_pgoff wrapping when you used mremap. But there was another case where we expand mappings hiding in plain sight: the automatic stack expansion. This fixes that case too. This one also found by Robert Święcki, using his nasty system call fuzzer tool. Good job.

2011-04-13avr32: add ATAG_BOARDINFOAndreas Bießmann
The ATAG_BOARDINFO is intended to hand over the information bd->bi_board_number from u-boot to the kernel. This piece of information can be used to implement some kind of board identification while booting the kernel. Therefore it is placed in .initdata section and can be accessed via the new symbol board_number only while initializing the kernel.

2011-04-13don't check platform_get_irq's return value against zeroUwe Kleine-König
platform_get_irq returns -ENXIO on failure, so !int_irq was probably always true. Better use (int)int_irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

2011-04-13avr32: init cannot ignore signals sent by force_sig_info()Matt Fleming
We can delete the code that checks to see if we're sending an ignored signal to init because force_sig_info() already handles this case. force_sig_info() will kill init even if the signal handler is SIG_DFL and the scenario described in the comment where init might "generate the same exception over and over again" cannot occur (force_sig_info() clears SIGNAL_UNKILLABLE to ensure that init will die). Also, the use of is_global_init() is not correct in the multhreaded case, as Oleg Nesterov explains, "is_global_init() is not right in theory, /sbin/init can be multithreaded. And, this doesn't cover the sub-namespace inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking closer I think you can simply remove this code." It seems this code was copied from arch/powerpc in March 2007 in commit 623b0355d5b1 "[AVR32] Clean up exception handling code" but the code was deleted from arch/powerpc in November 2009 in commit a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()" So catch up with powerpc and delete the bogus code.

2011-04-13USB: musb: blackfin: work around anomaly 05000450Mike Frysinger
DMA mode 1 data corruption anomaly on Blackfin systems. This issue is specific to the Blackfin silicon as the bug appears to be related to the connection of the musb ip to the bus/dma fabric. Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105) DMA mode 1 allows large size transfers to generate a single interrupt at the end of the entire transfer. The transfer is split up in packets of length specified in the Maximum Packet Size field for that endpoint. If the transfer size is not an integer multiple of the Maximum Packet Size, a short packet will be present at the end of the transfer. Under certain conditions this packet may be corrupted in the USB FIFO. Workaround: Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA mode 0 to transfer the short packet. As an example if your transfer size is 33168 bytes and Maximum Packet Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and the remainder (33168 mod 512) in DMA mode 0.

2011-04-13usb: musb: temporarily make it boolFelipe Balbi
Due to the recent changes to musb's glue layers, we can't compile musb-hdrc as a module - compilation will break due to undefined symbol musb_debug. In order to fix that, we need a big re-work of the debug support on the MUSB driver. Because that would mean a lot of new code coming into the -rc series, it's best to defer that to next merge window and for now just disable module support for MUSB. Once we get the refactor of the debugging support done, we can simply revert this patch and things will go back to normal again.

This patch fixes severe UBIFS bug: UBIFS oopses when we 'fsync()' an file on R/O-mounter file-system. We (the UBIFS authors) incorrectly thought that VFS would not propagate 'fsync()' down to the file-system if it is read-only, but this is not the case. It is easy to exploit this bug using the following simple perl script: use strict; use File::Sync qw(fsync sync); die "File path is not specified" if not defined $ARGV[0]; my $path = $ARGV[0]; open FILE, "<", "$path" or die "Cannot open $path: $!"; fsync(\*FILE) or die "cannot fsync $path: $!"; close FILE or die "Cannot close $path: $!"; Thanks to Reuben Dowle <Reuben.Dowle@navico.com> for reporting about this issue.

2011-04-13Input: add KEY_IMAGES specifically for AL Image BrowserJarod Wilson
Many media center remotes have buttons intended for jumping straight to one type of media browser or another -- commonly, images/photos/pictures, audio/music, television, and movies. At present, remotes with an images or photos or pictures button use any number of different keycodes which sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA, KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right. In my mind, KEY_MEDIA should be something more like a media center application launcher (and I'd like to standardize on that for things like the windows media center button on the mce remotes). KEY_CAMERA is used in a lot of webcams, and typically means "take a picture now". KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION might be the closest fit here, if you think "photo slide show", but it may well be more intended for "run application in full-screen presentation mode" or to launch something like magicpoint, I dunno. And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL Image Browser, the meaning of which I think is crystal-clear. I believe AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser by KEY_VIDEO, so I'm also adding appropriate comments next to those keys.

2011-04-13ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio()Eric Miao
This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup event. It is misinterpreted as a gpio irq not a PWER bitmask. Fixed this by converting the incorrect IRQ_TO_IRQ() to a correct version of irq_to_gpio(). Reported-by: Nick Bane <nickbane1@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
2011-04-13Btrfs: make uncache_state unconditionalChris Mason
The extent_io code can take cached pointers into the extent state trees, and these can make lookups much faster in common operations. The caching only happens when specific bits are set that prevent merging and splitting of the extent state. A help function was added to uncache the state, and it was testing the same set of conditionals. This can leak in very strange corner cases where the lock bit goes away unexpectedly. The uncaching should be unconditional. Once we have a ref on the extent we should always give it up. Signed-off-by: Chris Mason <chris.mason@oracle.com>

Change vddci as well as vddc when changing power modes on evergreen/ni. Also, properly set vddci on boot up for ni cards. The vbios only sets the limited clocks and voltages on boot until the mc ucode is loaded. This should fix stability problems on some btc cards.

2011-04-12drm/radeon/kms: clean up gart dummy page handlingAlex Deucher
As per Konrad's original patch, the dummy page used by the gart code and allocated in radeon_gart_init() was not freed properly in radeon_gart_fini(). At the same time r6xx and newer allocated and freed the dummy page on their own. So to do Konrad's patch one better, just remove the allocation and freeing of the dummy page in the r6xx, 7xx, evergreen, and ni code and allocate and free in the gart_init/fini() functions for all asics.
