2010-12-16PCI: Update MCP55 quirk to not affect non HyperTransport variantsNeil Horman1-0/+3
I wrote this quirk awhile ago to properly setup MCP55 chips on hypertransport busses so that interrupts reached whatever cpu happend to boot the kdump kernel. while that works well, it was recently shown to me that a a non-hypertransport variant of the MCP55 exists, and on those system the register that this quirk manipulates causes hangs if you write to it. Since the quirk was only meant to handle errors found on MCP55 chips that have a HT interface, this patch adds a filter to make sure the chip is an HT capable before making the needed register adjustment. This lets the broken MCP55s work with kdump while not breaking the non-HT variants. Resolves https://bugzilla.kernel.org/show_bug.cgi?id=23952 Tested successfully by the reporter and myself.

2010-12-08ARM: S3C24XX: Fix mess with gpio {set,get}_pull callbacksVasily Khoruzhick8-20/+81
Currently the {set,get}_pull callbacks of the s3c24xx_gpiocfg_default structure are initalized via s3c_gpio_{get,set}pull_1up. This results in a linker error when only CONFIG_CPU_S3C2442 is selected: arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f4): undefined reference to `s3c_gpio_getpull_1up' arch/arm/plat-s3c24xx/built-in.o:(.data+0x13f8): undefined reference to `s3c_gpio_setpull_1up' The s3c2442 has pulldowns instead of pullups compared to the s3c2440. The method of controlling them is the same though. So this patch modifies the existing s3c_gpio_{get,set}pull_1up helper functions to take an additional parameter deciding whether the pin has a pullup or pulldown. The s3c_gpio_{get,set}pull_1{down,up} functions then wrap that functions passing either S3C_GPIO_PULL_UP or S3C_GPIO_PULL_DOWN. Furthermore this patch sets up the s3c24xx_gpiocfg_default.{get,set}_pull fields in the s3c244{0,2}_map_io function to the new pulldown helper functions.

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.

Because it caused a chroot ttyname regression in 2.6.36. As of 2.6.36 ttyname does not work in a chroot. It has already been reported that screen breaks, and for me this breaks an automated distribution testsuite, that I need to preserve the ability to run the existing binaries on for several more years. glibc 2.11.3 which has a fix for this is not an option.

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>
