2008-10-03softirq, warning fix: correct a format to avoid a warningFrederic Weisbecker
Last -tip gives this warning: kernel/softirq.c: Dans la fonction «__do_softirq» : kernel/softirq.c:216: attention : format «%ld» expects type «long int», but argument 2 has type «int» This patch corrects the format type, and a small mistake in the "softirq" word.

2008-09-05drivers/mmc/card/block.c: fix refcount leak in mmc_block_open()Andrew Morton
mmc_block_open() increments md->usage although it returns with -EROFS when default mounting a MMC/SD card with write protect switch on. This reference counting bug prevents /dev/mmcblkX from being released on card removal, and situation worsen with reinsertion until the minor number range runs out.

2008-09-05forcedeth: fix kexec regressionRafael J. Wysocki
Fix regression tracked as http://bugzilla.kernel.org/show_bug.cgi?id=11361 and caused by commit f735a2a1a4f2a0f5cd823ce323e82675990469e2 ("[netdrvr] forcedeth: setup wake-on-lan before shutting down") that makes network adapters integrated into the NVidia MCP55 chipsets fail to work in kexeced kernels. The problem appears to be that if the adapter is put into D3_hot during ->shutdown(), it cannot be brought back into D0 after kexec (ref. http://marc.info/?l=linux-kernel&m=121900062814967&w=4). Therefore, only put forcedeth into D3 during ->shutdown() if the system is to be powered off. Signed-off-by: Rafael J.

2008-09-05sched: fix process time monotonicityBalbir Singh
Spencer reported a problem where utime and stime were going negative despite the fixes in commit b27f03d4bdc145a09fb7b0c0e004b29f1ee555fa. The suspected reason for the problem is that signal_struct maintains it's own utime and stime (of exited tasks), these are not updated using the new task_utime() routine, hence sig->utime can go backwards and cause the same problem to occur (sig->utime, adds tsk->utime and not task_utime()). This patch fixes the problem TODO: using max(task->prev_utime, derived utime) works for now, but a more generic solution is to implement cputime_max() and use the cputime_gt() function for comparison.

2008-09-05i2c: fix i2c-sh_mobile timing issuesMagnus Damm
This patch teaches the i2c-sh_mobile driver to make use of wait irqs. Without this patch only dte irqs are used which may lead to overruns and cases of missing stop and extra bytes being read on the i2c bus. Use of wait irqs forces the hardware to pause and wait until the cpu is ready. Polling is also reworked in this patch to fix ms delay issues.

2008-09-05sh: resume_kernel fix for kernel oops built with CONFIG_BKL_PREEMPT=y.Carmelo Amoroso
This patch fixes a problem within the SH implementation of resume_kernel code, that implements in assembly the bulk of preempt_schedule_irq function without taking care of the extra code needed to handle the BKL preemptible. The patch basically consists of removing this asm code and calling the common C implementation (see kernel/sched.c) as other archs do. Another change is the missing 'cli' macro invocation at the beginning of the resume_kernel.

2008-09-04V4L/DVB (8870): gspca: Fix dark room problem with sonixb.Hans de Goede
When using the sonixb driver in a dark room and given that the autoexposure algorithm starts with a setting most suitable for daylight, the picture produced by the cam may actually be 100% black leading to a avg_lum value of 0, so an avg_lum value of 0 does not always signal an exposure settings change (which it normally does). This patch adds a check for the really black image case and stops dropping all frames as invalid in this case.

to gspca. This patch makes gspca claim the USB-ID for sn9c101/2 cams with a TAS5110C1B sensor even if both gspca and sn9c102 are enabled, as these cams are much better supported under gspca (and extensively tested with gspca). It also removes an usb-id from sn9c102 for one more unsupported bridge sensor combo.

2008-09-04fujitsu-laptop: fix regression for P8010 in 2.6.27-rcJonathan Woithe
The following patch (based on a patch from Stephen Gildea) fixes a regression with the LCD brightness keys on Fujitsu P8010 laptops which was observed with the 2.6.27-rc series (basically they stopped working due to changes within the fujitsu-laptop and video modules). Please apply to 2.6.27-rc and acpi git. A more complete solution for this laptop will be included in an upcoming patch, hopefully for 2.6.28. In the meantime this restores most functionality for P8010 users.

2008-09-04PCI: fix pbus_size_mem() resource alignment for CardBus controllersLinus Torvalds
Commit 884525655d07fdee9245716b998ecdc45cdd8007 ("PCI: clean up resource alignment management") changed the resource handling to mark how a resource was aligned on a per-resource basis. Thus, instead of looking at the resource number to determine whether it was a bridge resource or a regular resource (they have different alignment rules), we should just ask the resource for its alignment directly. The reason this broke only cardbus resources was that for the other types of resources, the old way of deciding alignment actually still happened to work. But CardBus bridge resources had been changed by commit 934b7024f0ed29003c95cef447d92737ab86dc4f ("Fix cardbus resource allocation") to look more like regular resources than PCI bridge resources from an alignment handling standpoint.

2008-09-03x86: Change warning message in TSC calibration.Alok N Kataria
When calibration against PIT fails, the warning that we print is misleading. In a virtualized environment the VM may get descheduled while calibration or, the check in PIT calibration may fail due to other virtualization overheads. The warning message explicitly assumes that calibration failed due to SMI's which may not be the case. Change that to something proper.
