From: Jake Moilanen <moilanen@austin.ibm.com> In xics_get_irq(), for a real-to-virt irq lookup, go down the slowpath by looking through the entire virt_irq_to_real_map array if take a miss on the radix tree. This is possible, when an interrupt is taken before the driver has called request_irq() (eg IDE).

From: Anton Blanchard <anton@samba.org> - Merge some whitespace differences with the ameslab tree - We check for CPU_MASK_ALL in xics to send irqs to all cpus. In some cases CPU_MASK_ALL is smaller than the cpumask (eg NR_CPUS == 32 and cpumask is a long), so we mask it here to be consistent.

From: Linas Vepstas <linas@austin.ibm.com> This patch fixes multiple EEH-related bugs: - Fixes the eeh_check_failure() usage in an interrupt context. This routine is now safe to use in an interrupt. The fix was to build a cache of IO addresses and check that, instead of using the pci routines. - Merges in Olof Johansson's sizeof patch when checking for failure - Adds EEH tests to array/string reads - Fixes bugs with address resolution (some i/o addresses were handled incorrectly, resulting in EEH errors slipping by undetected.) - Adds EEH support to the PCI Hotplug system (so that devices that get added/removed get properly registered with the EEH subsystem.) - Fixes improper use of /proc filesystem. - Adds some misc statistics. While merging Linas' patch I also converted the proc usage to seq_single, used per cpu variables for the stats and removed the eeh-force-off option.

From: Linda Xie <lxiep@us.ibm.com> The changes in this patch are for multifunction cards insertions/removals and bug fixes: 1. fix up new nodes' linux_phandle field. 2. new nodes' phb, devfn(and so on) need to be fixed even the nodes don't have "interrupts". 3. change of_remove_node to non-recurisve func. The recursions will be done by the caller. 4. add a new function -- of_finish_dynamic_node_interrupts()

From: Rick Lindsley <ricklind@us.ibm.com> Fix bug #2230. I've corresponded with the submitter and he did find a real bug -- when we were merging I/O requests we didn't always take the oldest request start time, which would cause a couple of the calculations like wait time and average queue size to be too small. He found it mathematically but having done so, I think logic and inspection makes it easy to verify.

On a really small memory machine (or one with a monstrous kernel memory leak) we can end up calling blk_congestion_wait() before the waitqueue_heads are set up.

From: Matt Mackall <mpm@selenic.com> This piece of the THREAD_SIZE cleanup got dropped. If you make THREAD_SIZE > 8k, the init thread overlaps the .init section and gets smashed. I've gone ahead and killed INIT_THREAD_SIZE throughout as it wasn't doing much. This also saves 4k when we use 4k stacks. Please apply. Couple more minor pieces remaining.

keventd and friends are currently holding /dev/console open three times. It's all inherited from init. Steal the relevant parts of daemonize() to fix that up.

From: Manfred Spraul <manfred@colorfullife.com> print_objinfo() dumps the first few characters of an interesting object for debugging. It used the wrong object len (including debug padding, instead of just the data area), which could cause an oops if DEBUG_PAGEALLOC is enabled.

From: BlaisorBlade <blaisorblade_spam@yahoo.it>, and me - remove unused `file *' arg from do_write_mem() - Add checking for copy_from_user() failures in do_write_mem() - Return correct value from kmem writes() when a fault is encountered. A write()-style syscall's return values are: 0 when nothing was written and there was no error (someone tried to write zero bytes) >0: the number of bytes copied, whether or not there was an error. Userspace detects errors by noting that the write() return value is less than was requested. <0: there was an error and no bytes were copied

From: Chris Mason <mason@suse.com> reiserfs_file_write() can use stale metadata after a schedule. Two reiserfs_file_write bugs, where items can change during a schedule.

Andrew Morton authored
From: Chris Mason <mason@suse.com> Make sure reiserfs uses a reasonable number when restarting long unbounded transactions (creating holes or deleting files). Without this patch, the number of blocks requested grows with each transaction restart, until it hits MAX_BATCH_COUNT and starts forcing commits with every new transaction. Oleg Drokin tracked this bug down

From: Chris Mason <mason@suse.com> From: Jeff Mahoney <jeffm@suse.de> fsstress manages to setup a sequence of events that allow an attempt to perform direct-io on a tail. bh_result->b_page == NULL, which causes the PageLocked and PageWriteback checks to perform a NULL deref, causing the oops.

From: James Simmons <jsimmons@infradead.org> This patch merges two of the drawing functions. The patch uses aligned transfers when possible even on displays where the characters are not byte align. Tested on my my laptop for 12 bit width fonts and 8 bit wide fonts. It works very nicely.

There's no point in calling mark_page_accessed() here. The page is never on the LRU so all mark_page_accessed() will do is to set PG_referenced, which we immediately clear again.

Add a debug check for workqueues nested more than three deep via the direct-run-workqueue() path.
-
Andrew Morton authored
Because keventd is a resource which is shared between unrelated parts of the kernel it is possible for one person's workqueue handler to accidentally call another person's flush_scheduled_work(). thockin managed it by calling mntput() from a workqueue handler. It deadlocks. It's simple enough to fix: teach flush_scheduled_work() to go direct when it discovers that the calling thread is the one which should be running the work. Note that this can cause recursion. The depth of that recursion is equal to the number of currently-queued works which themselves want to call flush_scheduled_work(). If this ever exceeds three I'll eat my hat.

From: Stephen Smalley <sds@epoch.ncsc.mil> This patch fixes a bug in the SELinux compute_av code; the current code yields the right access computation but can cause unnecessary (but harmless) processing to occur when transition permission wasn't granted in the first place by the TE configuration. Thanks to Chad Hanson of TCS for reporting the bug.

From: Sam Ravnborg <sam@ravnborg.org> modpost or to be more specific sumversion.c was not behaving correct when used with O= and MODULE_VERSION was used. Previously it failed to use local .h when calculation the md-sum in case of a O= build. The following patch introduces the following: - A generic get_next_line() - Check that the topmost part of the directory matches - Using strrch when checking for file with suffix .o - Use NOFAIL for allocations in sumversion - Avoid memory leak in new_module The generic get_next_line will pay off when Andreas implmentation of storing symbol addresses in a seperate file is introduced.
