2009-06-24ACPI: Rename ACPI processor device bus IDZhao Yakui
Some BIOS re-use the same processor bus id in different scope: \_SB.SCK0.CPU0 \_SB.SCK1.CPU0 But the (deprecated) /proc/acpi/ interface assumes the bus-id's are unique, resulting in an OOPS when the processor driver is loaded: WARNING: at fs/proc/generic.c:590 proc_register+0x148/0x180() Hardware name: Sunrise Ridge proc_dir_entry 'processor/CPU0' already registered Call Trace: [<ffffffff8023f7ef>] warn_slowpath+0xb1/0xe5 [<ffffffff8036243b>] ? ida_get_new_above+0x190/0x1b1 [<ffffffff803625a8>] ? idr_pre_get+0x5f/0x75 [<ffffffff8030b2f6>] proc_register+0x148/0x180 [<ffffffff8030b4ff>] proc_mkdir_mode+0x3d/0x52 [<ffffffff8030b525>] proc_mkdir+0x11/0x13 [<ffffffffa0014b89>] acpi_processor_start+0x755/0x9bc [processor] Rename the processor device bus id. And the new bus id will be generated as the following format: CPU+ CPU ID For example: If the cpu ID is 5, then the bus ID will be "CPU5". If the CPU ID is 10, then the bus ID will be "CPUA". Yes, this will change the directory names seen in /proc/acpi/processor/* on some systems. Before this patch, those directory names where totally arbitrary strings based on the interal AML device strings. http://bugzilla.kernel.org/show_bug.cgi?id=13612 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-06-23ACPI: Add the reference count to avoid unloading ACPI video bus twiceZhao Yakui
Sometimes both acpi video and i915 driver are compiled as modules. And there exists the strict dependency between the two drivers. The acpi video bus will be unloaded in course of unloading the i915 driver. If we unload the acpi video driver, then the kernel oops will be triggered. Add the reference count to avoid unloading the ACPI video bus twice. The reference count should be checked before unregistering the acpi video bus. If the reference count is already zero, it won't unregister it again. And after the acpi video bus is already unregistered, the reference count will be set to zero. http://bugzilla.kernel.org/show_bug.cgi?id=13396 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-06-23ACPI: fix a deadlock in hotplug caseZhang Rui
we used to run the hotplug code in keventd_wq. But when hot removing the ACPI battery device, power_supply_unregister invokes flush_scheduled_work. This causes a deadlock. i.e 1. When dock is unplugged, all the hotplug code is run on kevent_wq. 2. the hotplug code removes all the child devices of dock device. 3. removing the child device may invoke flush_scheduled_work 4. flush_scheduled_work waits until all the work on kevent_wq to be finished, while this will never be true because the hotplug code is running on keventd_wq... Introduce a new workqueue for hotplug in this patch. http://bugzilla.kernel.org/show_bug.cgi?id=13533 Tested-by: Paul Martin <pm@debian.org> Tested-by: Vojtech Gondzala <vojtech.gondzala@gmail.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Reviewed-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-06-23mm: fix handling of pagesets for downed cpusDimitri Sivanich
After downing/upping a cpu, an attempt to set /proc/sys/vm/percpu_pagelist_fraction results in an oops in percpu_pagelist_fraction_sysctl_handler(). If a processor is downed then we need to set the pageset pointer back to the boot pageset. Updates of the high water marks should not access pagesets of unpopulated zones (those pointer go to the boot pagesets which would be no longer functional if their size would be increased beyond zero).

2009-06-23rmap: fixup page_referenced() for nommu systemsMike Frysinger
After the recent changes that went into mm/vmscan.c to overhaul stuff, we ended up with these warnings on no-mmu systems: mm/vmscan.c: In function `shrink_page_list': mm/vmscan.c:580: warning: unused variable `vm_flags' mm/vmscan.c: In function `shrink_active_list': mm/vmscan.c:1294: warning: `vm_flags' may be used uninitialized in this function mm/vmscan.c:1242: note: `vm_flags' was declared here This is because the no-mmu function defines page_referenced() to work on the first argument only (the page). It does not clear the vm_flags given to it because for no-mmu systems, they never actually get utilized. Since that is no longer strictly true, we need to set vm_flags to 0 like everyone else so gcc can do proper dead code elimination without annoying us with unused warnings.

2009-06-23mm: pass mm to grab_swap_tokenHugh Dickins
If a kthread happens to use get_user_pages() on an mm (as KSM does), there's a chance that it will end up trying to read in a swap page, then oops in grab_swap_token() because the kthread has no mm: GUP passes down the right mm, so grab_swap_token() ought to be using it. We have not identified a stronger case than KSM's daemon (not yet in mainline), but the issue must have come up before, since RHEL has included a fix for this for years (though a different fix, they just back out of grab_swap_token if current->mm is unset: which is what we first proposed, but using the right mm here seems more correct).

2009-06-23mm: don't rely on flags coincidenceHugh Dickins
Indeed FOLL_WRITE matches FAULT_FLAG_WRITE, matches GUP_FLAGS_WRITE, and it's tempting to devise a set of Grand Unified Paging flags; but not today. So until then, let's rely upon the compiler to spot the coincidence, "rather than have that subtle dependency and a comment for it" - as you remarked in another context yesterday.

Fixes a build error: clamp_align() should be moved as well, since it's only used by v4l_bound_align_image(). I'm attaching an alternate version that fixes this. Labeled the endif too.

2009-06-23V4L/DVB (11913): cx231xx: TRY_FMT should not actually set anythingTrent Piepho
In the TRY_FMT handler the function get_scale() is called to find what the scaler hardware will produce for a requested size. The problem is that get_scale(struct cx231xx *dev, ..., unsigned int *vscale, unsigned int *hscale) saves the calculated scale values into both the pointer arguments and into dev's hscale and vscale fields. TRY_FMT shouldn't actually change anything in the device state. The code to in get_scale() that writes to dev->[hv]scale can just be deleted. In all cases when dev's fields should be modified, get_scale() was called with get_scale(dev, ..., &dev->hscale, &dev->vscale), so dev was getting updated anyway. This didn't actually cause a problem because nothing ever actually made use of the hscale and vscale fields. I changed cx231xx_resolution_set() to use those fields rather than re-calculate them with a call to get_scale(). Updating [hv]scale in cx231xx_resolution_set() isn't necessary because every call of cx231xx_resolution_set() was already preceded by a call to get_scale() or setting the [hv]scale fields, so they will be always be up-to-date w.r.t. width and height. Removing the call to get_scale() from cx231xx_resolution_set() allowed making get_scale() a static function, which is a good thing for something with such a short name. There is already another function with the same name in the em28xx driver, but that one is static.

2009-06-23V4L/DVB (11912): em28xx: Use v4l bounding/alignment functionTrent Piepho
The v4l function has a better algorithm for aligning image size. It appears that the em2800 can only scale by 50% or 100%, i.e. the only heights supported might be 240 and 480. In that case the old code would set any height other than 240 to 480. Request 240 get 240, but request 239 and then you get 480. Change it to round to the nearest supported value.
