2010-12-07MN10300: Fix interrupt mask alteration function call name in gdbstubDavid Howells3-3/+6

2010-12-07cifs: allow calling cifs_build_path_to_root on incomplete cifs_sbJeff Layton3-5/+6
It's possible that cifs_mount will call cifs_build_path_to_root on a newly instantiated cifs_sb. In that case, it's likely that the master_tlink pointer has not yet been instantiated. Fix this by having cifs_build_path_to_root take a cifsTconInfo pointer as well, and have the caller pass that in.

2010-12-07cifs: fix check of error return from is_path_accessableJeff Layton1-1/+1
This function will return 0 if everything went ok. Commit 9d002df4 however added a block of code after the following check for rc == -EREMOTE. With that change and when rc == 0, doing the "goto mount_fail_check" here skips that code, leaving the tlink_tree and master_tlink pointer unpopulated. That causes an oops later in cifs_root_iget.

2010-12-07ALSA: hda - Always allow basic audio irrespective of ELD infoAnssi Hannula1-9/+7
Commit bbbe33900d1f3c added functionality to restrict PCM parameters based on ELD info (derived from EDID data) of the audio sink. However, according to CEA-861-D no SAD is needed for basic audio (32/44.1/48kHz stereo 16-bit audio), which is instead indicated with a basic audio flag in the CEA EDID Extension. The flag is not present in ELD. However, as all audio capable sinks are required to support basic audio, we can assume it to be always available. Fix allowed audio formats with sinks that have SADs (Short Audio Descriptors) which do not completely overlap with the basic audio formats (there are no reports of affected devices so far) by always assuming that basic audio is supported.

2010-12-07ALSA: hda - Do not wrongly restrict min_channels based on ELDAnssi Hannula2-5/+0
Commit bbbe33900d1f3c added functionality to restrict PCM parameters based on ELD info (derived from EDID data) of the audio sink. However, it wrongly assumes that the bits 0-2 of the first byte of CEA Short Audio Descriptors mean a supported number of channels. In reality, they mean the maximum number of channels (as per CEA-861-D 7.5.2). This means that the channel count can only be used to restrict max_channels, not min_channels. Restricting min_channels causes us to deny opening the device in stereo mode if the sink only has SADs that declare larger numbers of channels (like Primare SP32 AV Processor does). Fix that by not restricting min_channels based on ELD information.

2010-12-07autofs4 - remove ioctl mutex (bz23142)Ian Kent1-11/+1
With the recent changes to remove the BKL a mutex was added to the ioctl entry point for calls to the old ioctl interface. This mutex needs to be removed because of the need for the expire ioctl to call back to the daemon to perform a umount and receive a completion status (via another ioctl). This should be fine as the new ioctl interface uses much of the same code and it has been used without a mutex for around a year without issue, as was the original intention.

2010-12-06PM / Hibernate: Fix memory corruption related to swapRafael J. Wysocki5-22/+30
There is a problem that swap pages allocated before the creation of a hibernation image can be released and used for storing the contents of different memory pages while the image is being saved. Since the kernel stored in the image doesn't know of that, it causes memory corruption to occur after resume from hibernation, especially on systems with relatively small RAM that need to swap often. This issue can be addressed by keeping the GFP_IOFS bits clear in gfp_allowed_mask during the entire hibernation, including the saving of the image, until the system is finally turned off or the hibernation is aborted. Unfortunately, for this purpose it's necessary to rework the way in which the hibernate and suspend code manipulates gfp_allowed_mask. This change is based on an earlier patch from Hugh Dickins.

2010-12-06PM / Hibernate: Use async I/O when reading compressed hibernation imageBojan Smojver1-15/+38
This is a fix for reading LZO compressed image using async I/O. Essentially, instead of having just one page into which we keep reading blocks from swap, we allocate enough of them to cover the largest compressed size and then let block I/O pick them all up. Once we have them all (and here we wait), we decompress them, as usual. Obviously, the very first block we still pick up synchronously, because we need to know the size of the lot before we pick up the rest. Also fixed the copyright line, which I've forgotten before.

This is due to the typo in the for_each_sg() loop where the scatterlist pointer is used for obtaining the DMA buffer address and _not_ the SG list iterator. As a result all received data will be written only into the first DMA buffer while reading. While writing the data from the first DMA buffer is send to the device multiple times.

2010-12-04parisc: KittyHawk LCD fixGuy Martin1-4/+13
K class aka KittyHawk don't have LED support on their LCD. Installing HP-UX confirmed this. The current led_wq fills the LCD with black characters each time it runs. The patch prevents the led_wq workqueue and its proc entry to be created for KittyHawk machines. It also increase min_cmd_delay as currently, one character out of two is lost when a string is sent to the LCD.

2010-12-04parisc: convert the rest of the irq handlers to simple/percpuJames Bottomley6-11/+12
The generic conversion eliminates the spurious no_ack and no_end routines, converts all the cascaded handlers to handle_simple_irq() and makes iosapic use a modified handle_percpu_irq() to become the same as the CPU irq's. This isn't an essential change, but it eliminates the mask/unmask overhead of handle_level_irq().

2010-12-04parisc: fix dino/gsc interruptsJames Bottomley1-1/+1
The essential problem we're currently having is that dino (and gsc) is a cascaded CPU interrupt. Under the old __do_IRQ() handler, our CPU interrupts basically did an ack followed by an end. In the new scheme, we replaced them with level handlers which do a mask, an ack and then an unmask (but no end). Instead, with the renaming of end to eoi, we actually want to call the percpu flow handlers, because they actually have all the characteristics we want. This patch does the conversion and gets my C360 booting again. Signed-off-by: James Bottomley <James.Bottomley@suse.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
