We should amend that test for zombies to include the "dead" state as well.

Having necessary resources, I've decided to take over the maintenance of the defxx driver for the PDQ-based family of DEC FDDI controllers (the DEFEA for EISA and the DEFPA for PCI are the models currently handled). I've talked to Larry, the original author and the last maintainer of the code, and he's said he'd be happy about it. He's asked me to update his long-outdated contact information. Here is a patch to update the driver to the PCI version of the DMA API. The patch includes appropriate status and contact information updates.

From: Nathan Scott <nathans@sgi.com> XFS wants to use page->private as a bitmap of uptodate indicators for sub-page-sized blocks (which is one of the things ->provate was intended for). But someone needs to initialise ->private somewhere. best to do it in the page allocator, so the zeroness of a new page's ->private becomes a system-wide thing.

From: john stultz <johnstul@us.ibm.com> I've found a race in the mtrr ipi_handler() and set_mtrr() functions. Basically the server, set_mtrr() does the following: 1.1 initialize a flag 1.2 send ipi 1.3 waits for all cpus to check in 1.4 toggle flag 1.5 do stuff 1.6 wait for all cpus to check out 1.7 toggle flag again 1.8 return While the clients, running ipi_handler() do the following: 2.1 check in 2.2 wait for flag 2.3 do stuff 2.4 check out 2.5 wait for flag 2.6 return The problem is the flag is on the servers stack! So if 1.7 and 1.8 executes before 2.5 happens, the client's pointer to the flag becomes invalid (likely overwritten) which causes the client to never see the flag change, hanging the box. The patch fixes that by adding a final synchronisation step in which the controlling CPU waits for all the IPI'ed CPUs to complete.

From: Martin Pool <mbp@samba.org> ia64_mv_irq_desc returns a 'struct irq_desc', which had a forward declaration but did not actually exist. We're currently using a silly anonymous struct typedefed to irq_desc_t. Now add the structure name as well.

From: george anzinger <george@mvista.com> a) Fixes bug 858 (http://bugme.osdl.org/show_bug.cgi?id=858) The problem was caused by round off error in calculating the correct jiffies value in micro seconds to do the round up to jiffies. The fix is to do the round up AFTER conversion to jiffies, rather than before. This only affected the timeval to jiffies calculation. b) Changed the scale values to get the highest possible precision short of going to full 64-bit math. This is particularly useful in the scaling of the seconds part of time. The code now computes a trial value at compile time and adjusts the scaling if the result is less than 32 bits. c) Adds comments to time.h to remove (I hope) ALL the confusion that this file use to generate.

From: Peter Chubb <peterc@gelato.unsw.edu.au> Currently, do_setitimer() is used in several files, but doesn't appear in any header. Thus its declaration is repeated in some files, and its use causes a warning in others (because there is no declaration present). This patch: -- adds a couple of declarations to linux/times.h -- removes the (now duplicate) declarations from other files.

From: Ville Herva <vherva@niksula.hut.fi> NMI watchdog is nowadays supported on x86-64, too. The nmi-watchdog.txt document doesn't mention this. Here is a patch to add a few words on that.

From: jbarnes@sgi.com (Jesse Barnes) Currently, free_all_bootmem_core() assumes that the bdata for a given node will begin where the node's memory map begins. This isn't necessarily true on machines that use a virtual memory map (e.g. ia64 discontig machines), so we fix page to point to the first actual page of RAM on the node, which _does_ contain the bdata struct.

From: Andi Kleen <ak@muc.de> In some cases panic can be called with interrupts off. Don't trigger the NMI watchdog in this case when a panic= parameter is specified.

From: Matt Mackall <mpm@selenic.com> This only checks in the non-__ versions, as those are occassionally called inside things like kmap_atomic pairs which take a spinlock in with highmem. It's all conditional on CONFIG_DEBUG_SPINLOCK_SLEEP (which isn't quite the right name) so there's no overhead for normal builds.

cdrom_decode_status() can call cdrom_end_request() twice. The second call oopses because the first call destroyed the request. Fix it to only call cdrom_end_request() once. Jens has acked this change.

move_one_page() is awkward. It grabs an atomic_kmap of the source pte (because it needs to know if there's really a page there) and then it needs to allocate a pte for the dest. But it cannot allocate the dest pte while holding the src's atomic kmap. So it performs this little dance peeking at pagetables to predict if alloc_one_pte_map() might need to perform a pte page allocation. When I wrote this code I made it conditional on CONFIG_HIGHPTE. But that was bogus: even in the !CONFIG_HIGHPTE case, get_one_pte_map_nested() will run atomic_kmap() against the pte page, which disables preemption. Net effect: with CONFIG_HIGHMEM && !CONFIG_HIGHPTE we can end up performing a GFP_KERNEL pte page allocation while preemption is disabled. It triggers a might_sleep() warning and indeed is buggy. So the patch removes the conditionality: even in the !CONFIG_HIGHPTE case we still do the pagetable peek and drop the kmap if necessary. (Arguably, we shouldn't be performing the atomic_kmap() at all if !CONFIG_HIGHPTE: all it does is a pointless preemption disable). (Arguably, kmap_atomic() should not be disabling preemption if the target page is not highmem. But we're doing it anyway at present for consistency (ie: debug coverage) and because the filemap.c pagecache copying functions rely on kmap_atomic() disabling do_no_page() for all pages: see do_no_page()'s use of in_atomic()).

From: Oleg Drokin <green@namesys.com> This small patch fixes a savelinks problem on bigendian platforms, where savelinks were not working at all because of incorrect cpu->disk endianness conversion. Savelinks are used on reiserfs to remember "truncate" and "unlink" events so that if crash happens in the middle of truncate/unlink, we do not endup with lost or half truncated files.

From: Joe Thornber <thornber@sistina.com> Update the ioctl32 handlers for the 64-bit architectures to recognize the new Device-Mapper version 4 ioctls. The version 1 ioctls are still there. If/When the version 1 ioctls are removed, these same files will need to be updated again. I have been unable to test this patch yet, since I have not had any luck getting 2.6.0-test2 to compile on my ppc64 box (not a dm-related problem). But the patch is pretty trivial, so I'm pretty confident it will work. If anyone else can test this (on mips64, sparc64, parisc, or x86-64), let me know if you have any problems. [Kevin Corry]
