2007-02-12[WATCHDOG] timers cleanupJiri Slaby
- Use timer macros to set function and data members and to modify expiration time. - Use DEFINE_TIMER for single (platform dependent) watchdog timers and do not init them at run-time in these cases. - del_timer_sync is common in most cases -- we want to wait for timer function if it's still running.

2007-01-09[WATCHDOG] pcwd_usb.c - get heartbeat from dip switchesWim Van Sebroeck
The PCWD cards normally use the heartbeat that is set via the dip-switches of the card. There are only 3 switches, thus 8 combinations that each have a certain heartbeat. The card can however be programmed with a heartbeat from 1 till 65535 seconds. This is what our driver does: it programs the heartbeat on the card. There are however a lot of people that don't know that we set the heartbeat of the watchdog card to the value provided by the heartbeat module parameter. Instead they think that the heartbeat value is the same as set by the dip-switches. This patch changes the driver so that at startup you can take the heartbeat from the dip-switches. You do this by setting the heartbeat module parameter to 0. This patch also makes this the default behaviour. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2006-12-16Fix up mm/mincore.c error value casesLinus Torvalds
Hugh Dickins correctly points out that mincore() is actually _supposed_ to fail on an unmapped hole in the user address space, rather than return valid ("empty") information about the hole. This just simplifies the problem further (I had been misled by our previous confusing and complicated way of doing mincore()). Also, in the unlikely situation that we can't allocate a temporary kernel buffer, we should actually return EAGAIN, not ENOMEM, to keep the "unmapped hole" and "allocation failure" error cases separate. Finally, add a comment about our stupid historical lack of support for anonymous mappings. I'll fix that if somebody reminds me after 2.6.20 is out.

2006-12-16Make workqueue bit operations work on "atomic_long_t"Linus Torvalds
On architectures where the atomicity of the bit operations is handled by external means (ie a separate spinlock to protect concurrent accesses), just doing a direct assignment on the workqueue data field (as done by commit 4594bf159f1962cec3b727954b7c598b07e2e737) can cause the assignment to be lost due to lack of serialization with the bitops on the same word. So we need to serialize the assignment with the locks on those architectures (notably older ARM chips, PA-RISC and sparc32). So rather than using an "unsigned long", let's use "atomic_long_t", which already has a safe assignment operation (atomic_long_set()) on such architectures. This requires that the atomic operations use the same atomicity locks as the bit operations do, but that is largely the case anyway. Sparc32 will probably need fixing. Architectures (including modern ARM with LL/SC) that implement sane atomic operations for SMP won't see any of this matter.

2006-12-16Fix incorrect user space access locking in mincore()Linus Torvalds
Doug Chapman noticed that mincore() will doa "copy_to_user()" of the result while holding the mmap semaphore for reading, which is a big no-no. While a recursive read-lock on a semaphore in the case of a page fault happens to work, we don't actually allow them due to deadlock schenarios with writers due to fairness issues. Doug and Marcel sent in a patch to fix it, but I decided to just rewrite the mess instead - not just fixing the locking problem, but making the code smaller and (imho) much easier to understand.

2006-12-16[PATCH] pata_via: Cable detect errorAlan
The UDMA66 VIA hardware has no controller side cable detect bits we can use. This patch minimally fixes the problem by reporting unknown in this case and using drive side detection. The old drivers/ide code does some additional tricks but those aren't appropriate now we are in -rc. Without this update UDMA66 via controllers run slowly. They don't fail so it's a borderline call whether this is -rc material or not. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
