* [PATCH] drivers/rtc/rtc-rs5c372.c: fix a NULL dereferenceAdrian Bunk2006-11-251-3/+3
| | | | | | | | | | | | | | The correct order is: NULL check before dereference This was a guaranteed NULL dereference with debugging enabled since rs5c372_sysfs_show_osc() does actually pass NULL... Spotted by the Coverity checker.

* [PATCH] rtc class locking bugfixesDavid Brownell2006-11-255-11/+24
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] rtc framework handles periodic irqsDavid Brownell2006-11-252-1/+13
| | | | | | | | | | | | | | | | The RTC framework has an irq_set_freq() method that should be used to manage the periodic IRQ frequency, but the current ioctl logic doesn't know how to do that. This patch teaches it how. This means that drivers implementing irq_set_freq() will automatically support RTC_IRQP_{READ,SET} ioctls; that logic doesn't need duplication within the driver.

* [PATCH] fuse: fix Oops in lookupMiklos Szeredi2006-11-251-14/+38
| | | | | | | | | | | | | | | | | | 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. Thanks to Russ Cox for the bug report and test filesystem.

* [PATCH] initramfs: handle more than one source dir or file listThomas Chou2006-11-252-2/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] x86_64: fix bad page state in process 'swapper'Mel Gorman2006-11-231-3/+3
| | | | | | | | | | | | | | | | | | | 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(). It has been boot tested on x86, x86_64, ppc64 and ia64. Signed-off-by: Mel Gorman <mel@csn.ul.ie> Acked-by: Andre Noll <maan@systemlinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* | | [AGP] Allocate AGP pages with GFP_DMA32 by defaultLinus Torvalds2006-11-222-2/+2

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.

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.

* | | Don't call "note_interrupt()" with irq descriptor lock heldLinus Torvalds2006-11-222-7/+3

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.
