2006-11-26V4L/DVB (4849): Add missing spin_unlock to saa6588 decoder driverIra Snyder
Sparse noticed a lock imbalance in read_from_buf(). Further inspection shows that the lock should not be held when the function exits. This adds a spin_unlock_irqrestore(), so that every exit path of the read_from_buf() function is consistent. The unlock was missing on an error path. Signed-off-by: Ira W.

2006-11-25[PATCH] uml: make execvp safe for our usagePaolo 'Blaisorblade' Giarrusso
Reimplement execvp for our purposes - after we call fork() it is fundamentally unsafe to use the kernel allocator - current is not valid there. So we simply pass to our modified execvp() a preallocated buffer. This fixes a real bug and works very well in testing (I've seen indirectly warning messages from the forked thread - they went on the pipe connected to its stdout and where read as a number by UML, when calling read_output(). I verified the obtained number corresponded to "BUG:"). The added use of __cant_sleep() is not a new bug since __cant_sleep() is already used in the same function - passing an atomicity parameter would be better but it would require huge change, stating that this function must not be called in atomic context and can sleep is a better idea (will make sure of this gradually).

2006-11-25[PATCH] usb: ati remote memleak fixMariusz Kozlowski
This is a bug. When checking for ati_remote->outbuf we free freeing ati_remote->inbuf so we end up freeing ati_remote->inbuf twice. Also the checks for 'ati_remote->inbuf != NULL' and 'ati_remote->outbuf != NULL' are redundant as usb_buffer_free() does this.

2006-11-25[PATCH] Enforce "unsigned long flags;" when spinlockingAlexey Dobriyan
Make it break or warn if you pass to spin_lock_irqsave() and friends something different from "unsigned long flags;". Suprisingly large amount of these was caught by recent commit c53421b18f205c5f97c604ae55c6a921f034b0f6 and others. Idea is largely from FRV typechecking. Suggestions from Andrew Morton. All stupid typos in first version fixed. Passes allmodconfig on i386, x86_64, alpha, arm as well as my usual config. Note #1: checking with sparse is still needed, because a driver can save and pass around flags or something. So far patch is very intrusive. Note #2: techically, we should break only if sizeof(flags) < sizeof(unsigned long), however, the more pain for getting suspicious code into kernel, the better.

2006-11-25[PATCH] rtc class locking bugfixesDavid Brownell
I got a lockdep warning when running "rtctest" so I though it'd be good to see what was up. - The warning was for rtc->irq_task_lock, gotten from rtc_update_irq() by irq handlerss ... but in a handful of other cases, grabbed without blocking IRQs. - Some callers to rtc_update_irq() were not ensuring IRQs were blocked, yet the routine expects that; make sure all callers block IRQs. It would appear that RTC API tests haven't been part of anyone's kernel regression test suite recently, at least not with lockdep running.

2006-11-25[PATCH] rtc framework handles periodic irqsDavid Brownell

2006-11-25[PATCH] fuse: fix Oops in lookupMiklos Szeredi
Fix bug in certain error paths of lookup routines. The request object was reused for sending FORGET, which is illegal. This bug could cause an Oops in 2.6.18. In earlier versions it might silently corrupt memory, but this is very unlikely. These error paths are never triggered by libfuse, so this wasn't noticed even with the 2.6.18 kernel, only with a filesystem using the raw kernel interface.

Fix bug 7401. Handle more than one source dir or file list to the initramfs gen scripts. The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple space-separated sources in order to allow unprivileged users to build an image. There are two bugs in the current implementation that prevent this from working. First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it obviously can't open. Second, gen_initramfs_list.sh -l outputs multiple definitions for deps_initramfs -- one for each argument.

2006-11-23[PATCH] x86_64: fix bad page state in process 'swapper'Mel Gorman
find_min_pfn_for_node() and find_min_pfn_with_active_regions() both depend on a sorted early_node_map[]. However, sort_node_map() is being called after fin_min_pfn_with_active_regions() in free_area_init_nodes(). In most cases, this is ok, but on at least one x86_64, the SRAT table caused the E820 ranges to be registered out of order. This gave the wrong values for the min PFN range resulting in some pages not being initialised. This patch sorts the early_node_map in find_min_pfn_for_node().

2006-11-22[AGP] Allocate AGP pages with GFP_DMA32 by defaultLinus Torvalds
Not all graphic page remappers support physical addresses over the 4GB mark for remapping, so while some do (the AMD64 GART always did, and I just fixed the i965 to do so properly), we're safest off just forcing GFP_DMA32 allocations to make sure graphics pages get allocated in the low 32-bit address space by default. AGP sub-drivers that really care, and can do better, could just choose to implement their own allocator (or we could add another "64-bit safe" default allocator for their use), but quite frankly, you're not likely to care in practice. So for now, this trivial change means that we won't be allocating pages that we can't map correctly by mistake on x86-64. [ On traditional 32-bit x86, this could never happen, because GFP_KERNEL would never allocate any highmem memory anyway ] Acked-by: Andi Kleen <ak@suse.de> Acked-by: Dave Jones <davej@redhat.com> Cc: Eric Anholt <eric@anholt.net> Cc: Keith Packard <keithp@keithp.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-11-22[AGP] Fix intel 965 AGP memory mapping functionLinus Torvalds
This introduces a i965-specific "mask_memory()" function that knows about the extended physical addresses that the i965 supports. This allows us to correctly map in physical memory in the >4GB range into the GTT. Also simplify/clean-up the i965 case for the aperture sizing by just returning the fixed 512kB size from "fetch_size()". We don't really care that not all of the aperture may be visible - the only thing that cares about the aperture size is the Intel "stolen memory" calculation, which depends on the fixed size.

2006-11-22Don't call "note_interrupt()" with irq descriptor lock heldLinus Torvalds
This reverts commit f72fa707604c015a6625e80f269506032d5430dc, and solves the problem that it tried to fix by simply making "__do_IRQ()" call the note_interrupt() function without the lock held, the way everybody else does. It should be noted that all interrupt handling code must never allow the descriptor actors to be entered "recursively" (that's why we do all the magic IRQ_PENDING stuff in the first place), so there actually is exclusion at that much higher level, even in the absense of locking.
